Create Your Own CO Detector DigiKey

By using the serial terminal, I was able to capture about 2 hours of logging at about 1 sample every seconds. Figure 6 shows what is possible with the Arduino, some resistors, the sensor and some averaging. The next steps would be to use the sensor in a 3electrode configuration, which provides added stability, and signal amplification.
