MEMS Hydrogen sulfide digital display module PN:M1007Y Product description M1007Y is a micro metal oxide semiconductor gas sensor based on MEMS micro hot plate technology, used to detect hydrogen sulfide in the air. The production of the sensor combines MEMS silicon substrate technology, thin film technology, thick film technology, and metal packaging technology. When the module is in a polluted gas environment, the module will output a serial port signal. Detection gas type: hydrogen sulfide, odor Calibration Quick response (~15Sec.) Built-in temperature compensation Digital signal output, simple application Long life (~ 5 years) Long-term stability The module sensitivity can be adjusted according to requirements main application: ➢ Detection of hydrogen sulfide in civil, industrial and environmental protection ➢ Internet of Things, wearable devic

1. Calculation formula Concentration result = (high byte of concentration value *256 + low byte of concentration value)/coefficient; 2. Input algorithm As shown in the table above, the return value is 0x07 in high byte, 7 in base 10, and 0x17 in low byte, 23 in decimal. The output result is :(7*256+23) =1815; Precautions 1. The module should avoid contact with organic solvents (including silica gel and other adhesives), paints, pharmaceuticals, oils and high-concentration gases. 2. The module must not withstand excessive impact or vibration. 3. The module needs to be warmed up for more than 5...
