Product description: Grove is a carbon dioxide sensor, temperature and humidity (SCD30)
The Grove module from Seeed Studio is equipped with asensor of humidity, temperature and carbon dioxide. (SCD30) is ahigh-precisioncarbon dioxide sensor based onSensirion SCD30 sensor. The measurement range is from 0 ppm to 40,000 ppm and the measurement accuracy can reach± (30 ppm + 3%)between 400 ppm to 10,000 ppm. It is powered with the voltage from 3.3 to 5 V with the I2C interface.
The Grove module from Seeed was based onSDC30 from Sensirion equipped with aprecise sensorof carbon dioxide and based on the technology of measurement of dispersive IR (NDIR). The concentration of CO2 is measured usingthe dual-channel principle. SCD30 provides a stable and accurate monitoring of the level of CO2,temperature and humidity. It allows users to develop new solutions in the field ofresearch and monitoring ofthe environment.
