BM22S3031-1
DESCRIPTION
The BM22S3031-1 is a catalytic combustible gas detector sensor, mainly used to detect methane. When the gas concentration exceeds the default calibration concentration, 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.
Each BM22S3031-1 has been calibrated at the factory to maintain consistent characteristics. The calibrated alarm threshold is 9% LEL (Lower Explosion Limit), which is about 4500ppm.
