Carbon monoxide alarms, carbon monoxide detectors, smoke detectors

voice chip, can display the concentration of carbon monoxide gas, using electrochemical sensor, with high stability, low power consumption, small sensitivity drift and other characteristics. It is mainly used in places where carbon monoxide gas leakage may occur to detect carbon monoxide gas leakage and ensure human life safety.
