The Grove - SCD41 is a compact yet powerful 3-in-1 environmental sensor for CO2, Humidity and Temperature measurement. Based on Sensirion SCD41, the photoacoustic NDIR sensor technology enables high accuracy and wide measurement range. Its miniture size, large supply voltage, high robustness and adjustable power consumption allow it to perfectly integrate into a variety of environmental monitoring applications such as Smart Ventilation System.

• CO2 is a key indicator for indoor air quality as high levels compromise humans’ cognitive low power and well-being. The Grove - CO2 & Temperature & Humidity Sensor - SCD41 enables smart ventilation systems to regulate ventilation in the most energy-efficient and human-friendly way. Moreover, indoor air quality monitors and other connected devices based on the SCD41 can help maintain low CO2 concentrations and comfortable Temperature & Humidity for a healthy, productive environment.
• We've released the Seeed Gas Sensor Selection Guide and the Grove Selection Guide, it will help you choose the Grove that best suits your needs.
• This product is Grove - CO2 & Temperature & Humidity Sensor for Arduino (SCD30) - 3-in-1 lighter version. The SCD41 packs are cheaper and lighter.

Upgrade to Industrial Solutions

Get Started with Industrial Sensors

• SenseCAP S210x series industrial sensors provide an out-of-box experience for environmental sensing. Please refer to the S2103 Wireless CO2, Temperature, and Humidity Sensor with higher performance and robustness for air quality monitoring.

With the SenseCAP S2110 Grove converter and S2100 data logger, you can easily turn the Grove into a LoRaWAN® sensor. Seeed not only helps you with prototyping but also offers you the possibility to expand your project with the SenseCAP series of robust industrial sensors.

The IP66 housing, Bluetooth configuration, compatibility with the global LoRaWAN® network, built-in 19 Ah battery, and powerful support from APP make the SenseCAP S210x the best choice for industrial applications. The series includes sensors for soil moisture, air temperature and humidity, light intensity, CO2, EC, and an 8-in-1 weather station. Try the latest SenseCAP S210x for your next successful industrial project.

What is PASens® Technology?

PASens® Technology is based on the photoacoustic sensing principle. The photoacoustic sensing principle allows extreme miniaturization of the CO2 sensor without compromising sensor performance due to the fact that the sensor sensitivity is independent of the optical cavity size. The reduced size and the smaller number of integrated components result in a highly price-efficient BOM structure. Thanks to the miniaturizing and economical BOM structure of these new CO2 sensors, the SCD4x will open up numerous possibilities for a whole new set of products and applications.
