Product Description

A carbon monoxide detector for the Arduino-based DIY security system. The carbon monoxide detector is a semiconductor gas sensor tuned to detect carbon monoxide. It is in the same family of devices as the smoke detector sensor, measuring the change in surface conductivity of tin dioxide in the presence of carbon monoxide. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance.
