The MQ-5 LPG and natural gas sensor detects combustible gas leaks by measuring the concentration in air. It works at 5V DC and gives an analog output (a variable voltage that rises with gas concentration) readable on any Arduino or ESP32 analog pin. The mq5 gas sensor detects gas from 200 to 10,000 ppm (parts per million, a measure of gas concentration in air).
Power consumption is around 150mA, so connect it to a dedicated supply and not directly from a microcontroller pin. Students and safety project builders use this gas detector for kitchen gas alarms and IoT monitoring builds. Connect to 5V, GND, and read the analog pin. StemVolt provides this sensor with trusted quality and ensuring reliable performance.
