    When accurately measuring, the proper alarm point for the gas detector should be determined after considering the temperature and humidity influence. Notifications: When the sensor in preheating or working, do not connect VC on the two pins, it need one resistor of 50-100Ωin series, otherwise, it will destroy the sensor. Basic application circuit
