The sensor is a simple and stable circuit with a TTL DO pin.
The device sensitivity may vary due to oxygen concentration.
It is very sensitive to methane making it quite useful for detecting systems

This methane gas sensor module contains onboard voltage regulator, pull-up resistors to define a default state, a potentiometer for sensitivity, and a capacitor for noise filtering. It has two inbuilt LEDs i.e power LED and a digital output indication LED.
