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.

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.


  • Air Purifier
  • Environmental Monitoring
  • Plant Environmental Monitoring System
  • Arduino weather station

Upgrade to Industrial Solutions

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 the economical BOM structure of these new CO2 sensors, the SCD4x will open up numerous possibilities for a whole new set of products and applications.
