The MQ-6 gas sensor module detects LPG, propane, and butane gas leaks by measuring their concentration in the air. It works at 5V DC and gives an analog output (a voltage that rises as gas concentration increases) readable on any Arduino or ESP32 analog pin. The mq6 gas sensor detects gas from 200 to 10,000 ppm (parts per million, a measure of gas density in air).
The propane gas sensor output also responds to alcohol vapour, so avoid using it near cleaning sprays. The operating temperature range of -20 to 40 degrees Celsius suits most indoor environments. Students and safety project makers for kitchen alarms and gas leak detectors. Connect to 5V, GND, and read the analog output pin. buy this mq6 gas sensor from StemVolt.
