MQ-7 Gas Sensor Module for Carbon Monoxide

MQ-7 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(Parts Per Million). The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.

Specifications :

• Power requirements : VCC – 5V±0.1
• DO output : TTL digital 0 and 1 (0.1 and 5V)
• AO output : 0.1-0 .3 V (relative to pollution), the maximum concentration of a voltage of about 4V
• Detection Gas: Carbon Monoxide
• Concentration: 10-10000ppm
• Supply Voltage: <10V
• Heater Voltage: 5.0V ± 0.2V
• Load Resistance: Adjustable
• Heater Resistance: 31Ω ± 3Ω
• Heater Consumption: <350mW

Application:

• For the household or environment detection carbon monoxide detection devices, fit for the detection of carbon monoxide and town gas.
