Product Summary

Module MQ-4 gas, methane sensor module in stock

 

Features

1, with the directions of the signal output.
2, two-way signal output (analog output, and TTL level output)
3, TTL output valid signal is low. (When low output signal light, and can be connected directly to the microcontroller)
4, 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.
5, liquefied petroleum gas, natural gas, city gas, better sensitivity.
6, has a long life and reliable stability
7, rapid response and recovery characteristics
