Carbon Monoxide Gas Sensor MQ-7 - Arduino Project Hub

Today I also expect your feedback, but only of a positive nature: with the MQ-7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem. I followed the recommendation to use a 10KOhm resistor and soldered the MQ7 to the PCB. It doesn't matter which side and how around ...
