Description
Carbon dioxide sensor with analog and digital output. It is powered with 5 V, it works withthe Arduino modules. The kit includes a cable adapted to DFRobot IO Expansion Shield.
Botland is an official distributor of DFRobot open-source hardware. Every roboticist and practitioner of emerging technology has heard at least once of DFRobot solutions, built above all around Arduino. Our range holds original DFRobot products only.
Communication
The sensor is equipped with a digital and an analog output. The voltage at the analog output decreases along with increasing CO2 concentration. The excitation threshold, after which the switching of the digital output can be set via the integrated potentiometer.
The product is compatible with Arduino Sample code and detailed information can be found inthe user's guide. |
The sensor works with any microcontroller that has analog inputs, includingArduino. To read data, just connect the power supply and the output pin to any analog input of the microcontroller and to read the measurement result.
Example of connecting the sensor.
Specification
- Supply voltage: 5 V
- Based on MG811 module: documentation
- Communication:
- the analog signal: the value decreases with the increase of the concentration of particles in the air
- digital signal: informing about the exceeding of the threshold set by the potentiometer
- Cable for connection with: DFRobot IO Expansion Shield
- Board sizes: 32 x 42 mm
Detailed data regarding the accuracy and operating conditions of the sensor, and charts can be found in thedocumentation.
Set includes:
- CO2 sensor
- Connecting cable
Based on MG811 module (documentation)

Question: Hello I wanted to buy and use this sensor , what do I need to have , so that I can use it , I'm a novice , I understand that for the sensor you need the DFRobot Gravity - IO Expansion Shield , and what next to that ? How to read the value ? Some kind of display or connect.with phone/computer ? What are the possibilities ? Greetings
