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

In this tutorial we are going to create an alarm using a laser beam and a PIR sensor (passive infrared motion sensor).
Getting started with electronics and sensing the world around you is now easier than ever with the new all-in-one Arduino Sensor Kit from Arduino, in partnership with Seeed. The 10 most popular modules and sensors for your Arduino UNO have been integrated onto a single board, providing plug-and-play convenience without the need for any soldering or wiring! Combining basic Grove sensors and actuators for the Arduino UNO, the kit contains a base shield featuring the following modules that can be connected either through the digital, analog, or I2C connectors: An OLED screen4 digital modules (LED, button, buzzer and potentiometer)5 sensors (light, sound, air pressure, temperature, and accelerometer) Just plug the Arduino Sensor Kit into the Arduino UNO, then you're ready to follow the Plug, Sketch & Play online lessons that make getting started a breeze. The kit is equipped with 16 Grove connectors, which when placed on the board, offer functionality to the various pins. With seven digital connections, four analog connections, four I2C connections, and a UART connection, the base shield can be easily mounted onto an Arduino UNO board and programmed through the Arduino IDE. Now available from the Arduino Store, the Arduino Sensor Kit comes as a standalone kit for only €23.00 / US$25.00, or can be purchased with the Arduino UNO Rev3 board as a great value bundle for €38.70 / US$39.80.
