The TP401 Gas Sensor module is useful for monitoring air purity indoors. It can detect CO and a wide range of other harmful gases, but, due to a limited detection range, it should be used only when qualitative results are needed. Example applications are air recirculation, ventilation systems, and refreshing sprayers. The sensor is linear and should be roughly sensitive to 0-20 ppm CO from 0-4 V. Note: the sensor requires 2-3 minutes to warm up initially and 48 hours of operation to stabilize completely.
