MQ-7 CO Carbon Monoxide Coal Gas Sensor Module

The MQ-7 CO Carbon Monoxide Coal Gas Sensor Module measures the amount of CO in the atmosphere and provides an analogue voltage as a result. 10 to 10,000 ppm concentrations can be measured with the sensor.

The sensor uses less than 150 mA at 5 V and can function in temperatures ranging from -10 to 50°C.

There are analogue and digital outputs available on this module. With the setting on the board, adjusting the threshold level for digital output is a simple process. Micro-controllers, Arduino, and other platforms can be easily interfaced with the MQ-7 sensor module.

Typical Testing Conditions:

The temperature was 20°C ± 2°C.
Temperature: 65% ± 5% R.H.
Standard Test Circuit: Vc = 5.0V ± 0.1V, Vh = 5.0V ± 0.1V for high, 1.5V ± 0.1V for low.

Characteristics:

• The analogue output voltage increases with increasing concentration.
• The more sensitive carbon monoxide detection.
• Four screw holes allow for simple positioning.
• With dependable stability and an extended service life.
• Quick reaction times and recuperation traits.
