The ULPSM-CO V2 is a small form factor, ultra-low power CO sensor that produces a linear voltage output proportional to CO concentration from 0 to 500 ppm. This CO module combines the novel millimeter thin electrochemical sensor technology from SPEC Sensors, Inc. with an ultra-low power analog front end. The SPEC Sensor is the thinnest on the market, providing for a smaller overall profile, and even less power consumption than our previous module
