MQ7 Carbon Monoxide Gas Sensor Module
The MQ7 Carbon Monoxide (CO) Gas Sensor Module detects CO concentrations. It measures CO gas levels from 20 to 2000 parts per million (ppm). The module provides an analog resistance output. This output facilitates interfacing with microcontrollers via an Analog-to-Digital Converter (ADC). Operation requires a 5V heater coil and a load resistance. The sensor exhibits high sensitivity and rapid response characteristics. It is suitable for integration into electronic projects and systems. This module supports environmental sensing applications.
