mq2 gas sensor analog output

Configure and read out the Raspberry Pi gas sensor (MQ-X)

On the opposite side is RX1, which is connected to the analog pin (A0) of the MQ2 sensor. Also connect 3.3V from the Raspberry Pi (LV) and 5V (HV) to the TTL. And also 5V to the VCC pin of the gas sensor and GND from the Raspberry Pi comes to GND on the LV and HV side of the TTL, as well as to GND of the MQ2. Schematically the whole looks as ...

MQ-6 Gas Sensor Pinout, Specs, Equivalent, Circuit & Datasheet

20-04-2018 · The MQ-6 sensor module comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas. When it comes to measuring the gas in ppm the analog pin has to be used, the analog pin also TTL driven and works on 5V and hence can be used with most common microcontrollers.

MQ2 Gas Sensor Tutorial for Arduino, ESP8266 and ESP32

15-09-2020 · The MQ2 gas sensor has an operating voltage between 4.5V and 5V that is also used as heater for the surface of the SnO2. Therefore the microcontroller we use has to provide a stable 5V output. Arduino microcontroller have already an operation voltage of 5V but we have to power the ESP8266 and ESP32 boards via USB to get an 5V output.
