Description
High-precision sensor that measures the concentration of CO2 (carbon dioxide) in the air. It is equipped with a UART interface, it works with a voltage from 4.5 V to 5.5 V. It operates in the range from 0 to 50000 ppm. The kit includes a cable adapted toDFRobot IO Expansion Shield. The module is characterized by high sensitivity, high resolution, low power consumption, fast response time, high stability and long service life. It is not affected by water vapor and is non-toxic. The sensor finds applications in refrigerating facilities, internal systems of air quality, in the processes of the monitoring of livestock and agricultural production, etc.
Communication
The sensor is equipped with UART interface, works with multiple microcontrolers, includingArduinoandRaspberry Pi.
