MG811 Carbon Dioxide Sensor For Carbon Dioxide Detector Module

This product is not available in your location yet

Description: 1. MG811 is a highly accurate and sensitive Carbon Dioxide (CO2) sensor designed for use in carbon dioxide detector modules. It utilizes an electrochemical gas sensor element to detect CO2 levels. 2. Features: Compact size (35mm x 16mm), low power consumption (<10mA), adjustable alarm threshold level, high accuracy (+/- 3% for 0-5000ppm CO2 range), and long sensor life. 3. Applications: Ideal for monitoring CO2 levels in greenhouses, laboratories, industrial processes, vehicle interiors, and home automation systems to ensure optimal indoor air quality and safety. 4. Operating Principle: The MG811 sensor measures the change in voltage generated due to the CO2 gas reaction with the sensor element to determine CO2 levels. This information is then transmitted to a microcontroller or display device for interpretation and action (alarm, logging, etc.). 5. Communication Interface: The sensor offers various communication interfaces such as I²C, UART, and PWM to allow seamless integration
