SPEC Sensors, LLC Carbon Monoxide Sensor
This blog is meant to talk about the 968-020 carbon monoxide sensor kit from SPEC Sensors. This is a development tool for testing carbon monoxide sensors. The kit comes with five sensors: three of these—the 110-102—are through hole and can be used on the board that comes with the kit; two of them—the 110-109—do not have headers but rather an option for headers or surface mount options.
The sensor picks up the carbon monoxide in the air and converts this to a current which is converted into a voltage. This device is good from 0 – 1,000 ppm for a sensing range. The device puts out a voltage for the gas, a reference voltage which is about half of the supply voltage, and a temperature voltage. There is a sensitivity code written on each device that can be used to derive the gas concentration in the air.
This is a product that could be seen in any kind of carbon monoxide sensor. Using this product was a fun way to see how an electrochemical sensor can work. The hardware was easy to understand and hook up, and there is a lot of information on their equations to show the actual parts per million of gas concentration in the air.
More information about this product can be seen on this Another Geek Moment video and on EEWiki. If there are any questions, feel free to ask them in the TechForum.
