This is MQ-7 Carbon Monoxide Sensor. It detects the concentrations of CO gas and outputs it`s reading as an analog voltage. The sensor has a long life, high sensitivity and quickly response time. The sensor output signal is an analog resistance.
The sensor can measure a low concentration of carbon dioxide. The sensitivity of the gas concentration from 20ppm to 2000ppm. The sensor can operate in temperatures from -10 to 50 C, and consumes less than 150mA at 5V.
Analog and digital outputs – with the amplifier output signal and adjusting the heating element sensor. You can configure the sensor to a certain threshold, and connect to the digital input of the microcontroller.
