"For our Senior Design group project in hydroponics, we had quite a few sensors to implement, some with associated circuitry and others that were easily implemented into the overall system.Actually, the K30 was probably the easiest of all to implement considering the design and "pre-programming" your company offers.

We appreciate the support of your company and would like you to know that your sensor helped play an integral part in our understanding of sensors and their system integration. Thanks!"

CO2Meter.com will showcase several new products at the AHR Expo, January 25-27, 2010 in Orlando, Florida. AHR is the largest heating, air-conditioning and ventilation trade show in the US. New products we will highlight at this show include:

Cellular Data Logger. This battery-operated device Measures CO2, temperature, and humidity, then sends the levels by cellular modem to a custom website where you can see them in real-time.

K-30 Probe. Designed for students to measure CO2 in science projects, the Probe has a heavy-duty integrated USB power cable, is dirt and dust resistant, and uses our graphing software and development kit with source code.

K-33 Data Logger. The K-33 CO2/temp/%RH data logger product line now offers a wall power supply so you can sample for weeks or months, or an internal air pump and tubing to remotely draw air from a sealed enclosure.

Tube Cap Kit. In response to customer demand, our engineers have developed a Tube Cap Kit to isolate the K-30 and K-33 ELG sensors from harsh environments.

If you plan to be in Orlando in January, send us an e-mail and we'll get you a free pass to the show.

Our sensor and data logger software is constantly being updated for you.

If you use any one of our data loggers, sensor development kits, or K-30 Probe, you need to check out the latest version of our SDK (software development kit). For example, as the result of customer feedback, we've added many more features to the graphing tool to make it easier to use.

Have a suggestion for the SDK? Contact us and we'll put it on the list for future releases.

researchers say that this anxiety is promordial.

It would appear that our genetic legacy also features some very intriguing left-overs, which are not necessarily of use to us today. One such feature is the fact that the human brain triggers a primordial type of fear when exposed to increased amounts of carbon dioxide. The cortex seems to have what scientists have termed a built-in sensor against high CO2 concentrations, which circumvents other alert mechanisms.

The new study could have significant implications for people who suffer from chronic panic attacks. The condition may come from mechanisms such as the recently discovered one, which malfunctions in some individuals. The work may also be able to finally explain why people drawing deep breaths can calm down when suffering from such anxiety attacks, LiveScience reports.

The investigation was conducted on unsuspecting mice by a research team at the University of Iowa. They found that CO2 does not interfere with the body's functions directly. Instead, it reacts with water to form carbonic acid, the same substance found in soft drinks. They hypothesize that this increased acidity acting on fear-sensing neural circuits inside the brain, is responsible for generating the suffocation sensation.
