"The K-22 CO2 sensor is excellent to use in a research lab application. The PWM chip allowed us to seamlessly integrate with PIC microcontrollers to make a closed control loop. It was so easy to comm- unicate between the K-22 PWM and the PIC circuit. I will definitely be looking to this line of products (CO2 as well as others) in further sensing applications. Thanks!"

With the new school year, we have been hearing from teachers and students across the country that it is impossible to find a reasonably-priced CO2 meter to use in scien- tific experiments or classroom instruction. After much haggling with our supplier, we made a committment to purchase a large quantity of these desktop CO2 meters with data logging and to offer them to you at an incredibly low price.

The CAM CO2 Meter & Data Logger includes a wall plug, 12V auto adapter and a USB cable that allows it to be plugged into any PC or laptop. Download the free software, purchase 1-4 additional USB extension cables, and the CAM becomes a wired remote CO2 data logger that can be used up to 64 feet away!

Wired into a demand controlled ventilation system or stand-alone, the eSense FAI can help achieve LEED certification

The eSense Fresh Air Indicator (FAI) is a simple, low-cost and maintenance-free carbon dioxide alarm designed to be installed in areas like office buildings or classrooms where the carbon dioxide levels need to be monitored for indoor air quality. An audible alarm and flashing light indicate when recommended indoor carbon dioxide levels are exceeded. 

• Three LEDS: red, yellow, green
• Alarm configuration: Green > 800ppm, Yellow 800-1400ppm, Red < 1400ppm
• Audible alarm & mute button
• Internal Analog Output (O-10v or 4-20mA)
• Optional 24VAC adapter for remote placement
• Maintenance-free in normal applications

In June, 2009, Dr. Margaret Chan, from the World Health Organization (WHO) officially declared H1N1 as the first influenza pandemic of the 21st century. Since then, many countries have been infected with the virus and have begun to fight it in various ways.

For example, in the United States the H1N1 virus is being taken seriously by all levels of government. The Center for Disease Control has issued recommendations to protect the public, including these common sense rules:

• Cover your nose and mouth when you cough or sneeze
• Wash your hands often with soap and water
• Avoid touching your eyes, nose or mouth
• Stay home if you get sick

Note that the first recommendation is to avoid passing the virus through airborne contact! Millions of viruses can float suspended in water droplets expelled by infected people via coughs and sneezing. According to OSHA tests, some of these droplets can travel up to 6 feet read more...
