MQ-4 Gas Sensor Module

Description

This MQ4 - Methane Gas sensor module can sense the presence of compressed Natural Gas sensors (CNG), methane(CH4) etc. in the air. This is a very easy to use low-cost semiconductor Gas sensor Module with analog and digital output. It requires no external components just plug in VCC & ground pins and you are ready to go. It is small sensitive to alcohol and smoke. This module has an IC LM393 is a dual differential comparator; this means that it accepts 2 inputs for comparison. It compares these voltage inputs and determines which is the larger value. Its has 3362 potentiometer by which we can control the flow of current. 

Feature:

• Its used to sense the gas
• Its used in gas detecting applications like it can be used in safety applications, Metro , Buses.
• Its has MQ-4 gas sensor 
• Its made in India
