Product Overview
A small, stable MOS CO sensor for family, industrial and commercial leakage alarms.
During the 1.5 V low-temperature phase the sensor detects carbon monoxide; the 5 V high-temperature phase cleans other adsorbed gases.
A simple load-resistor circuit converts the conductivity change into a concentration-related output signal.
