The Most Common Factors Associated With Mold Growth And Where To Look


Black mold can be a fatal problem if not taken care of. However, it is better to take preventive measures rather than waiting for it to occur and then seeking for cure. Following are the factors that can cause mold to grow in your surroundings.

Humidity

It means the percentage of water content in the air is a vital nourishing factor for molds. It favors the growth of black mold. If the relative humidity level is greater than 55 percent, your indoor environment has the perfect conditions for the promotion of its growth.

Flooding

Black mold also gets favorable growth conditions after an area is flooded. What makes flooded areas more immune to such hosts is that draining them out can take days and that gives it sufficient time for growth.

Leaky Roofs

The water stains that commonly occur in apartments should be alarming enough. A check should be kept in the upper flows for signs of water leakage or pipe damage.

Humidifiers

The use of humidifiers can be dangerous if it is abused. So, if you have some humidifiers at your place, ensure that your relative humidity (RH) level remains within sixty percent. To ensure this, installation of a relative humidity sensor is required. One of the best humidity sensors switches off the humidifiers itself if the relative humidity level exceeds the limit. Thus, black molds can be avoided.

Damp Spaces

Such spaces are often ignored during the daily cleaning of the house and are considered nothing more than storage places. However, it is such places that have cooler temperature. This means condensation. Obviously, condensation being the source of water droplets favors mold growth.

Houseplants

The more plants you have, the more you will water them. The more you water them, the more of the water would be evaporated. The more the process of evaporation occurs, the more the amount of moisture will enter your environment. Thus, it will provide favorable conditions for black mold.

Fading Wall Paint

If you see your wallpaper peeling out, it is not because the tape wasn't good enough. The water seeping through your walls is always the major reason.

Blocked Gutters

Indoors drying appliances: Appliances that generate steam if placed inside the house can affect the relative humidity level. Once it shoots, the prevention of such colonies becomes tough. So, placing such appliances outside might do the trick.

Bathrooms

This is no accumulation of dirt; it is pure colony of fungi, and proper measures have to be adopted in order to relieve oneself from it.

Wireless Humidity and Temperature Sensor: 5 Common Uses for Environmental Sensors


1. Temperature and Humidity: You can monitor critical temperatures continuously and in real time with a system that wirelessly monitors the temperature of equipment (cold or hot) anywhere in your building such as: kitchens, laboratories, pharmacies, nursing and medical stations as well as off-site facilities. The system can page, e-mail and visually alert any computer screen the moment food, lab samples, pharmaceuticals or other temperature sensitive items are outside the prescribed parameters. Wireless humidity and temperature sensors allow flexibility, reduce wiring cost and transmit data up to 100 feet without the use of a repeater. The unit is battery powered using two AA batteries and it uses a 418 MHz transmitter so you can change the location of the sensors without worrying about extra labor costs.

2. Barometric pressure: The wireless sensor system also provides Web-based monitoring humidity, and barometric pressure in critical HVAC and refrigeration applications. The compact wireless "end devices" mount on the wall in clean rooms, laboratories, museums, computer server rooms, warehouses, and any remote facility. You can select one end device to serve as an internal or external sensor, in order to monitor temperature and humidity both inside and outside a climate-controlled facility. Another bonus is that these devices are designed for harsh environments such as outdoor weather, HVAC ducts, freezers and refrigerators.

3. Water Detection Sensors: These detection sensors have a remote monitoring system which uses an 802.11 Wi-Fi network of water leak detection in pipelines, agricultural fields, server rooms and more and is available with various other applications.

4. CO2 Sensors: With these sensors you can monitor the CO2 levels continuously and in real time. It is a system that uses your existing Wi-Fi network and is ideal for indoor air quality, HVAC management, environmental surveillance, greenhouses, and incubators. You will receive a page, e-mail and visual alert on any computer screen whenever your measurements are outside the prescribed parameters, making your home and/or workplace safer.

5. PH Sensors: This sensor is ideal for storage applications where continuous pH monitoring is required such as: health care, food storage and inside a laboratory. As with the CO2 sensors, you will receive a page, e-mail and visually alert on any computer screen whenever your measurements are outside the prescribed parameters.

Just some of the various reasons to install them, environmental sensors are easy to add to your life, take up little space, and work effectively to make your work easier, safer and more effective.

Fibre Optic Sensors - Common Applications and Types


Fibre optic sensors are used within a wide range of different industries. Fundamentally they utilise fibre optics to remotely sense and are frequently used due to their small size and also the fact that no power is needed to operate the sensor. There are two major types of fibre optic sensor, intrinsic and extrinsic; the former uses optical fibre as the actual sensor element whilst the latter use fibres to relay signals from the sensor to a processing unit.

Intrinsic fibre optic sensors utilise the properties of glass and the fibre geometry to measure a number of different quantities. Essentially they measure how light passes through the sensing fibre; then convert this light behaviour into a unit, such as pressure or temperature. They can be used in a variety of different situations; here are just four of the common types of fibre optic sensor used today.

• Strain sensing is a frequent application for this type of sensor as they are capable of measuring mechanical strain directly. This is measured through the ways the geometric properties of the fibre change under strain; this is manifested as a change to the light refractive properties of the fibre.
• Temperature sensing is carried by a practically identical sensor set up. The one difference is that to assess the temperature, the expansion or contraction of the fibre is measured. In this instance, instead of mechanical strain being the force, it is how the fibre is directly affected by changes in temperature that is measured.
• Pressure sensing can be carried out through the same measurement of expansion and contraction. Typically, a fibre will be inserted into a rigid steel tube with a diaphragm at the end. This diaphragm, coupled to the fibre acts as the sensor.
• Sensors are also used to measure humidity. These are slightly different from other sensors as they do not take their measurements from the direct strain placed upon the fibre. Instead, a special coating capable of absorbing and releasing water vapour is used; this coating is attached to the fibre and as it either expands or contracts in correlation to the water vapour it holds, it strains the fibre, changing its refractive properties and subsequently provides a measurement.

These four uses for fibre optic sensors are just some of the most common. Today sensors are used throughout the world in a variety of industries, from biomedical applications and aircraft to petroleum drilling sites.




In a wide variety of industries fibre optic sensors are used as a reliable and agile sensing solution. It is the specific properties of fibre optics and their ability to work remotely without power that makes them popular for a range of industrial and medical applications.

Seven Common Questions About Home Weather Stations (And Their Answers)


Have you ever started a conversation with a comment about the weather?

Has an unexpected weather change created havoc in your garden, pond or aviary, or even damaged your home?

Have you ever noticed that the weather you experienced during your day was different to that reported by your nearest official weather station?

Have you ever left home wearing clothing that was too warm or cool for the day's weather?

Or would you just like to know a little more about your local weather than you can find out from TV or the internet?

A "yes" answer to any of those questions suggests that you could benefit from owning your own home weather station.

Now is a great time to get a weather station of your own. Recent improvements mean they have never before been so powerful, so easy to use and install, or so well priced.

I'm sure you'd like to know more, so here are some answers to the seven most commonly asked questions about home weather stations:

1. What is a Home Weather Station?

A modern home weather station consists of one or more sensors which collect data on temperature, humidity, air pressure, rainfall, and wind direction and speed from around your home. This information is transferred to a receiver/display console located in the comfort of your home, and updated frequently. The cost and usefulness rises with the number of sensors used.

2. A friend had a weather station and there were cables everywhere. Why would I want that?

No problems there. Older home weather stations sent data along thin cables, but you will have no difficulty in finding suitable units which use radio to transmit the weather information, over effective ranges of 330 feet or more. No wires, no holes in the roof or wall.

3. How difficult are they to set up?

With a little preplanning, it takes little time or effort to get a home weather station up and running. Once you have chosen the positions for the sensors and receiver, and checked that they are in contact with each other, all you need is some very basic ability with a drill and screwdriver.

4. How reliable are home weather stations, and what do they cost?

Home weather stations vary from a simple temperature recorder to multi sensor arrays. Costs start from less than US$30 for the simplest models with a single sensor, up to around $5-600 for a quality home weather center. More specialized units, designed more for commercial and agricultural uses, run up to $3,000. As in most things, you get what you pay for, and you can expect a $500 model to be stronger and more reliable than something from the lower end of the price range.

Nevertheless, with a little bit of preparation and maintenance, you can expect the cheaper models to give good consistent service.

Much more information can be found at www.home-weather-stations-guide.com

5. Will I just see raw weather data, or can I expect more?

You can expect a lot more. Most weather stations offer a range of calculated functions such as relative humidity, dewpoint, heat index and wind chill factor, depending on which sensors are used. Many have a basic forecasting ability, correct about three times out of four. Many include alarm functions which can be preset at critical high or low temperatures, high wind speeds etc. Almost all show the time, and many of the simpler ones can double as an alarm clock - imagine being woken in the morning with the console showing both the time and the outside temperature.

6. Can I connect my weather station to my computer?

In most cases, yes. In fact many of the better weather stations include software allowing easy connection. A wide range of commercial weather software is compatible with most weather station models.

Take it a step further and you can even link your weather station with automatic heating and watering systems (and much more). Imagine the savings in water use if your irrigation system was controlled by something a little smarter than a timer.

7. What other uses could a home weather station have?

I've mentioned a number of uses in the answers above, but a home weather station can help out anywhere that wind, rainfall or temperature data is useful. Most stations will handle several temperature sensors - you could check soil temperature to help guide you with spring or fall plantings, pool temperatures, or even temperatures in a baby's nursery inside your home.

Or you could run a very simple system monitoring temperatures in an outdoor aviary or greenhouse.

On a different track, you can upload your data to a web page - many people do - or contribute to the overall USA weather picture by sending your information to CWOP (Citizen Weather Observer Program)

There are so many ways to benefit from a home weather station. But to my mind, I've left the best to last.

By observing the weather around your home, you are opening up a much wider field - the enjoyment of the natural world.

As you see patterns develop in the information you have collected, you'll start to appreciate the weather maps, weather warnings, satellite images, radar and forecasts more. You'll find yourself watching the clouds, and how they change with variations in air pressure or wind direction, and you may even improve on the official forecasts.

And overall you'll find yourself paying more attention to the world outside - not just the sky, wind and clouds but all other aspects of the natural world.

So if you can see a need for a home weather station, go ahead and get one that suits you - you'll find a link to a helpful website just below the end of this article. But don't be surprised if your horizons expand well beyond your own backyard.
