MQ2 Gas Sensor Tutorial for Arduino, ESP8266 and ESP32

+

Sep 15, 2020· Like the ESP8266, the ESP32 the operation voltage of the ESP32 is and therefore too low for the MQ2 gas sensor, that has an operation voltage of 5V. But if we power the ESP32 board via USB, the input voltage of the board before the voltage regulator is 5V and accessible via the V5 pin of the EPS32 ESPWROOM32.
