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.

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
Answer: A microcontroller, such as an Arduino board, is required for proper operation of the sensor. The IO Expansion Shield overlay is not required, but will make it easier to connect the sensor. The measurement results will be available in the Arduino IDE serial monitor, but can be output to any display.

Execution ok. The sensor does what it can, but to measure accurately it requires a stable adc and power supply.
