Gravity: CO2 Sensor for Arduino
Overview
The SEN0159 is an analog carbon dioxide sensor module based on the MG811 electrochemical probe. It is designed for use with the Gravity interface system and includes onboard signal conditioning to output a linear analog voltage corresponding to CO2 concentration. The module requires a 5V power supply to drive the internal heater and is compatible with microcontrollers operating as low as 3.3V.
Why Choose This Part
The module features a standardized 3-pin Gravity connector that simplifies wiring to Arduino and other development platforms. It incorporates an onboard heating circuit and signal amplification, reducing the external component count for electrochemical gas sensing.
Applications
Key Specifications
Getting Started
Connect the module to an analog input pin on an Arduino or ESP32 using the provided 3-pin Gravity cable. Ensure the power supply can provide at least 500mA at 5V for the sensor heater, and allow the sensor to preheat for at least 48 hours before initial calibration to ensure stable readings.
