The Grove – SCD41 is a compact yet powerful 3-in-1 environmental sensor capable of measuring CO2 concentration, humidity, and temperature. Powered by the advanced Sensirion SCD41 chip and utilizing Photoacoustic NDIR sensing technology (PASens), it delivers high accuracy and a wide measurement range. Its miniature size, broad voltage compatibility, high robustness, and adjustable low power consumption make it ideal for integration into a variety of applications, including smart ventilation systems, indoor air quality monitors, and environmental monitoring projects.
Photoacoustic NDIR Sensing Technology (PASens): Real-time CO2 detection with high accuracy of (40 ppm + 5%) and a measurement range from 400 to 5,000 ppm.
3-in-1 Environmental Monitoring: Integrated humidity and temperature sensors with advanced compensation algorithms for reliable and accurate RH and T readings.
Ultra-Compact Size: Tiny form factor of just 10.1 10.1 6.5 mm for space-efficient designs.
Flexible and Robust: Supports a wide supply voltage (2.4V5.5V), robust against external stress, and adjustable power consumption down to <0.4 mA average.
CO concentration is a key indicator of indoor air quality, directly impacting human cognition, comfort, and well-being. The Grove – CO, Temperature & Humidity Sensor (SCD41) enables smart systems to regulate ventilation efficiently, maintaining low CO levels and providing a healthier, more productive environment.
