BMA36M303
The BMA36M303 is a catalytic combustible gas detector module composed of a breakout board and the gas detector sensor BM22S3031-1. The product reads the gas concentration and alarms via UART interface.
The BMA36M303 is mainly used to detect methane. When the gas concentration exceeds the default calibration concentration, the voltage output of the alarm pin STA (pin 1) 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 (STA).
BMA36M303 has been calibrated at the factory to maintain consistent characteristics. The calibrated alarm threshold is 9% LEL (Lower Explosion Limit), approximately equivalent to 4500ppm.
BMA36M303 has the same functions as the BM22S3031-1. The difference between them is that the BMA36M303 uses level shift circuit and a LDO IC HT7825 to break out the BM22S3031-1’s pins to match BMCOM connectors and can directly connect to BMduino development boards, such as BM53A367A.
You can use the product with other development boards, such as Arduino UNO, as well.
