Product description: Gravity - CO2 sensor - SCD41 - IR - I2C - 400 - 5000 ppm - DFRobot SEN0536
CO2 carbon dioxide sensor from DFRobot equipped with the SCD41 system from Sensirion . It is based on the photoacoustic NDIR detection principle and Sensirion's patented PAsens and CMOSens technologies. Signal compensation is implemented using the built-in temperature and humidity sensor, temperature and humidity data outputs are also available.
What is carbon dioxide?
CO2, or carbon dioxide, is a key factor affecting indoor air quality. Its high level threatens the cognitive abilities and well-being of a person. It should be monitored on an ongoing basis, and any deviations from the norm should be immediately signaled.
Special features of the module
- Measurement of three environmental values - CO2, temperature and humidity
- Compact dimensions, while maintaining high precision and stability of measurement
- Can be used in energy-saving projects due to low current consumption < 4 mA
Suggested use
- Monitoring of CO2 concentration in rooms
- Environmental monitoring in the greenhouse
- Intelligent ventilation systems
- IoT and Smart Home applications
Product compatible with Arduino and Raspberry Pi!
