I2C Sensor Interface is Easy to Use

I2C (pronounced I-squared-C) is a world- wide standard used for communications between micro-controllers and many other devices including our K series sensors. I2C makes bi-directional communi-cation between any two I2C devices easy.

After months of research, we've found a 0-100% carbon dioxide sensor to meet our customers most demanding specifications. It is the perfect solution for scientists and researchers who need to measure ultra-high levels of CO2. 

It provides:

• High speed, real time measurement
  
• High degree of accuracy
• Low cost of use

This precision sensor uses Aluminus Indium Antimonde on a Gallium Arsenide wafer substrate combined with a non-dispersive infrared technology to achieve a sensor that is unique in the industry.

The aSense GH measures carbon dioxide and temperature in the air, then sends the readings to your climate control system. It can also be used as a stand-alone device to drive an exhaust fan or an air duct damper.

Greenhouses, mushroom farms, poultry barns, vinyards, and meat processing plants aren't the best environment for electronics. Combine dirt, dust, extreme temperature and humidity with wall washing and hose over-spray, and the average sensor won't stand up to the challenge.

The aSense GH is different.

The IP54 enclosure protects against dirt, dust, and water spray, while the printed circuit board is fully coated to provide a second level of protection from the elements. this makes the aSense GH your best value when designing a climate control system in an extreme environment.

For years, agriculturalists have used carbon dioxide to kill insects in sealed vegetable, grain and fruit storage containers. The benefits are obvious: Because CO2 is not a chemical insecticide, it does not leach into the food, making it totally safe for human consumption.

But does that mean CO2 can be used to fumigate live plants? While the evidence says "yes", it isn't an easy solution.

The first problem with using CO2 to fumigate is that to be effective, the CO2 level must be maintained above 40% over 7-15 days in order to kill every type of insect. For example, in their paper "Carbon dioxide as a potential fumigant for termite control" researchers at the University of Hawaii found that exposure to 50% carbon dioxide for 60 hours resulted in approximately 70% termite mortality, while complete mortality was recorded after 120 hours.
