Description

Gas Sensor(MQ2) module is useful for gas leakage detecting(in home and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen, somke and so on. Based on its fast response time. measurements can be taken as soon as possible. Also the sensitivity can be adjusted by the potentiometer.
MQ-2 gas sensor has high sensitivity to LPG, Propane and Hydrogen, also could be used to Methane and other combustible steam, it is low cost and suitable for various applications.
Using high-quality dual-panel design, with a power indicator and TTL signal output instructions; With a the DO switch signal (TTL) output, and AO analog signal output; TTL output valid signal is low level; (When the low level output signal lights, it can be connected directly to the microcontroller or relay module)
TTL output signal can be connected directly to a microcontroller IO port or connect to the relay module, potentiometer is used to adjust the output level transition threshold
