MQ7-Carbon Monoxide Gas Sensor Module

MQ7-Carbon Monoxide 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 microcontrollers, Arduino and etc. This product is known as Gas Sensor, Carbon Monoxide Sensor, CO Sensor, MQ-7, MQ7, Carbon Monoxide (CO) Gas Sensor, Carbon Monoxide Gas Sensor, Carbon Monoxide Gas Sensor Module, CO Gas Sensor, CO Gas Sensor Module, Gas Sensor, MQ7 Carbon Monoxide (CO) Gas Sensor Module, Sensor
