Grove - SCD41 Environmental Sensor (CO2, Humidity, Temperature)
The Grove - SCD41 is a compact yet powerful 3-in-1 environmental sensor for measuring CO2, humidity and temperature. Based on Sensirion SCD41, the photoacoustic NDIR sensor technology enables high accuracy and a wide measurement range. Due to its small size, large supply voltage, high robustness and adjustable power consumption, it can be perfectly integrated into a variety of environmental monitoring applications such as the Smart Ventilation System.
Features
- Photoacoustic NDIR sensor technology PASens®: The embedded Sensirion SCD41 enables real-time CO2 detection with a high accuracy of up to ±(40 ppm + 5 %) and a wide measurement range of 400 to 5,000 ppm
- 3-in-1 environmental sensor: The integrated humidity and temperature sensor has an algorithm that enables excellent on-chip signal compensation and additional RH and T outputs
- Compact size: The smallest form factor of 10.1 x 10.1 x 6.5 mm³ enables space-saving integration
- Suitable for various applications as required: Supports a wide supply voltage of 2.4 V - 5.5 V, robustness against external loads and adjustable current consumption down to < 0.4 mA on average
Application
- Air purifier
- Environmental monitoring
- System for monitoring the plant environment
- Arduino weather station
- Upgrade to industrial solutions
