MQ7 Carbon Monoxide Gas Sensor Module

MQ7 Carbon Monoxide (CO) Gas Sensor Module for Air Quality Monitoring

This MQ7 Carbon Monoxide (CO) Gas Sensor Module offers a reliable solution for detecting CO concentrations in the air. It's designed for easy integration into various electronic projects and systems. The sensor accurately measures CO gas levels ranging from 20 to 2000 parts per million (ppm). Known for its high sensitivity and rapid response time, the MQ7 provides crucial data quickly. Its output is an analog resistance, simplifying the interface with microcontrollers. Powering the heater coil with 5V and adding a load resistance is all that's needed. Connect the output to an Analog-to-Digital Converter (ADC) for precise readings. Ideal for DIY enthusiasts, engineers, and educational purposes, this module is a fundamental component for environmental sensing. Ensure safety and monitor air quality effectively with this robust CO sensor. It's a versatile mini component for your sensor-based applications.
