Overview
Great and powerful sensor for everyone that wants to know the exact concentration of CO2(Carbon Dioxide) in the air.
This is the first CO2 sensor compatible with Arduino. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (the voltage is lower than the threshold), a digital signal (ON/OFF) will be released.
- It has MG-811 sensor module which is highly sensitive to CO2 and less sensitive to alcohol and CO, low humidity & temperature dependency.
- Onboard heating circuit brings the best temperature for sensor to function. Internal power boosting to 6V for heating sensor best performance.
- This sensor has an onboard conditioning circuit for amplifying output signal.
To ease the difficulty of using this CO2 sensor, a Gravity Interface is adapted to allow plug&play. The Arduino IO expansion shield is the best match for this CO2 senor connecting to your Arduino microcontroller.
This is an electrochemical Arduino-based CO2 sensor, it is suitable for qualitative analysis.
- Air Quality Control
- Ferment Process Control
- Room Temperature CO2 concentration Detection

Learn to set up an Arduino Nano RP2040 Connect to use MicroPython.
Team Ikaro is a vibrant group of high school students from the Pacinotti Archimede Institute in Rome, sharing a strong passion for electronics and turning heads in the world of robotics! Specializing in Soccer Lightweight games (where robot-soccer players compete to score goals on a miniature field), they clinched the first place at the Romecup 2024 and won Italy’s national Robocup in Verbania earlier this year – earning the right to compete in the world championships in Eindhoven, where they placed third in the SuperTeam competition. The brains behind the bots Utilizing the versatile Arduino Nano RP2040 Connect, the team has crafted highly efficient robots that feature ultrasound sensors, PCB boards, a camera, four motors, a solenoid kicker and omni-directional wheels, all meticulously assembled in the school’s FabLab. Mentored by professor Paolo Torda, Team Ikaro exemplifies the spirit of innovation and teamwork bringing together three talented students: Francesco D’Angelo, the team leader, focuses on system design and mechanics; Flavio Crocicchia, the software developer, ensures the robots’ brains are as sharp as possible; Lorenzo Addario specializes in camera software, making sure the robots can “see” and react swiftly on the field. Their combined efforts have led to a seamless integration of hardware and software, and established a foundation of passion and ambition for future success in their careers. Future goals After their first taste of global competition, Team Ikaro is determined to continue refining their robots, leveraging every bit of knowledge and experience they gain – whether in the classroom, lab, or live challenges. At Arduino, we are proud to sponsor such brilliant young minds and look forward to seeing what they will accomplish next!
