MQ7 CO Carbon Monoxide Coal Gas Sensor Module

MQ-7 CO Carbon Monoxide Coal Gas Sensor
Module detects the concentrations of CO in the air and outputs its
reading as an analog voltage. The sensor can measure concentrations of
10 to 10,000 ppm.

The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.

This module provides both digital and
analog outputs. The threshold level for digital output can be easily
adjusted using the preset on the board. The MQ-7 sensor module can be
easily interfaced with Micro-controllers, Arduino and etc.

Standard Test Conditions
