MQ7 Gas Sensor – CO Carbon Monoxide Sensor

Description

The MQ7 Gas Sensor module detects gas leakage in home and industry.

The MQ7 Gas Sensor can detect Carbon Monoxide.  It can detect the presence of  carbon Monoxide gases at concentrations from 20 to 2000 ppm.

This module provides both digital and analog outputs.  MQ7 gas sensor module can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi etc

The MQ series of gas sensors use a small heater inside with an electrochemical sensor. They are sensitive to a range of gasses and are used indoors at room temperature.

Due to its fast response time and high sensitivity, measurements can be taken as soon as possible. The sensor sensitivity can be adjusted by using the potentiometer.

Features:

• High sensitivity and fast response
• Wide detecting scope
• stable and Long life
• Simple drive circuit
• Analog and Digital Outputs

Pinout:

• Vcc – Power Supply (5V)
• GND – Ground
• AO – Analog Output
• DO – Digital Output
