DFrobot Gravity - Carbon Dioxide Sensor CO2 IR V2.0 - analog

High-precision sensor that measures the concentration of CO2 (carbon dioxide) in the air. Equipped with analog output, works with a voltage 5 V. Operates in the range from 400 to 5000 ppm. The kit includes a cable adapted to cap DFRobot IO Expansion Shield. The module is characterized by high sensitivity, high resolution, low power consumption, fast response time, high stability and long service life.

Sensor with analog output. The voltage at the analog output increases along with the increase of the CO2 concentration.

The product is compatible with Arduino

Sample code and detailed information can be found inthe user guide.

The sensor works with any microcontroller that has analog inputs, includingArduino. To read data, simply connect the power and the output pin for any analog input of the microcontroller and then, read the measurement result.
