DESCRIPTION

The BM22S2021-1 is a smoke detector sensor with two channels (LED transmitters) to detect white smoke and black smoke. Each sensor has been calibrated at the factory. When the concentration of smoke exceeds the default calibration, the voltage output of the alarm pin (pin 5) changes from low level to high level (default). It is easy to make a gas detector by supplying power to this sensor and monitoring the alarm output pin.
