CO2 Carbon Dioxide Sensor Module
A high-accuracy CO2 (carbon dioxide) sensor module designed for air quality monitoring, HVAC control, and environmental sensing applications. Compatible with Arduino, ESP32, Raspberry Pi, and other popular microcontroller platforms. Outputs CO2 concentration data via UART or analog signal for easy integration into your projects.
Key Features
- Measures CO2 concentration in the range of 400 – 5000 ppm (varies by model)
- High accuracy with automatic baseline correction (ABC)
- Dual output: UART (serial) and analog voltage output
- Fast warm-up time and stable long-term performance
- On-board status LED indicator
- Wide operating voltage: 4.5V – 5.5V
- Compact form factor with mounting holes
Typical Applications
- Indoor air quality (IAQ) monitoring systems
- HVAC automation and ventilation control
- Smart home and IoT air quality sensors
- Greenhouse and grow room CO2 monitoring
- School and office air quality displays
Pin Description
- VCC – 4.5V to 5.5V power supply
- GND – Ground
- TX / RX – UART serial communication
- AOUT – Analog output (0V – 2V proportional to CO2 level)
Works with Arduino Uno, Nano, Mega, ESP8266, ESP32, STM32, and Raspberry Pi via UART. Ideal for DIY air quality monitors and environmental data loggers.
