MG812 gas sensor is chemical type gas sensor that adopts solid electrolyte cell principle, used to detect carbon dioxide. When sensors are exposed to CO2, battery is positive and negative electrode reaction, the sensor produces electromotive force between sensitive electrode and reference electrode, the output voltage signal can be detected carbon dioxide. CO2 Sensors are used to measure the levels of carbon dioxide (CO2). It is important to monitor this gas as it is an indicator of CO2 emission levels, ventilation quality and combustion industrial processes.

Features:

  1. Small sizes
  2. low power consumption
  3. high sensitivity and good selectivity
  4. Less affection by temperature and humidity
  5. Steady performance and repeatability

Package Includes:

1 x Winsen MG812 Mini Size Solid Electrolyte CO2 Gas Sensor

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
