MQ7 Carbon Monoxide Gas Sensor

This is a simple-to-use MQ7 Carbon Monoxide Gas Sensor, suitable for sensing CO concentrations in the air. The MQ-7 can detect CO-gas concentrations anywhere from 10 to 1000 ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC. This sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board below.

• High sensitivity to carbon monoxide
• Stable, long life and low cost
• Good sensitivity to Combustible gas in wide range
• High sensitivity to Natural gas
• Simple drive circuit

• Domestic gas leakage detector
• Industrial CO detector
• Portable gas detector

Package Includes:

• 1 x MQ7 Carbon Monoxide Gas Sensor
