Soldered 333107 CO sensor MQ7 breakout
Description
The MQ7 gas sensor detects the presence of carbon monoxide (CO) in the air. While it detects liquid alcohol most effectively, it also measures the concentration of substances in gaseous form quite reliably. The sensor requires little time to heat up in order to function properly.
The breakout board operates with both digital (DO) and analogue signals (AO). Digital output is obtained by setting threshold values using the potentiometer. Analogue output varies depending on the gas intensity around the sensor.
