Product details
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
