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.
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.
