• Operating Voltage: DC5V
• Range: 10~1000 PPM
• Characteristic Gas: 100 PPM CO
• Sensitivity: 3%

Description:

MQ-7 CO Carbon Monoxide Coal Gas Sensor Module detects the concentrations of CO in the air and outputs its reading as an analogue voltage. The sensor can measure concentrations of 10 to 10,000 ppm. The sensor can operate at temperatures from -10 to 50C and consumes less than 150 mA at 5 V. This module provides both digital and analogue 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.

Specification:

Features:

• The analogue output voltage, the higher the concentration the higher the voltage.
• The carbon monoxide detection with better sensitivity.
• There are four screw holes for easy positioning.
• With a long service life and reliable stability.
• Rapid response and recovery characteristics.

Package Included:

1 x MQ-7 CO Carbon Monoxide Coal Gas Sensor Module For Arduino
