MQ-7 CARBON MONOXIDE SENSOR MODULE

Detects CO gas concentrations from 10 to 1000ppm. Dual signal outputs: An analog output (0V to ∼5V), the higher the gas concentration, the higher the voltage, and a digital TTL level output to signal the presence or absence of gas. The TTL threshold is adjustable with the onboard potentiometer. Operating voltage: 5 Volts DC, maximum power consumption 800mW (160mA at 5V). Fast response and recovery characteristics, long life and reliable stability.
