1 x MQ7 Co gas sensor. 1 x USB cable. Jumper wire. Principle: MQ7 Carbon monoxide sensor can detect CO gas and export both digital (0/1) and analog signals to Arduino. The TTL pin will export low voltage when CO GAS is detected. The analog pin will export voltage that is correlated to CO Gas density. Schematic:

2/4/2020· I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.

Description. This is a MQ7 Gas sensor (CO), suitable for sensing Carbon Monoxide concentrations (PPM) in the air. MQ7 Gas sensor can measure CO concentrations ranging from 20 to 2000 ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. MQ7 gas sensor has high sensitivity to Carbon Monoxide.

Gas sensor. This analog gas sensor has a small heating part with an electronical chemical sensor. It is suitable for indoor usage. The sensor can output exact values only after warmup phase. Caution: sensor gets hot while usage!
