Multi-Talented Module Masters Air Purifier And HVAC Applications


Sensirion’s SVM30 is a multi-gas, humidity, and temperature sensing module suitable for users that prioritize lean development and products. The module contains an SGP30 gas sensor as well as an SHTC1 humidity and temperature sensor. 


The SGP30 gas sensor combines multiple metal-oxide sensing elements – the pixels – on one chip, offering the possibility of measuring a total VOC signal (tVOC) and a CO2 equivalent signal (CO2eq) with one single sensor chip. The sensor also offers calibrated air quality output signals as well as compensation of humidity cross-sensitivity.


The gas sensing element features resistance against contamination by siloxanes, enabling unique long-term stability and low drift. Furthermore, the integrated SHTC1 humidity and temperature sensor covers a humidity measurement range of 0 to 100% relative humidity (RH) and a temperature measurement range of -20°C to 85°C with a typical accuracy of ±5% RH and ±1°C.


The gas, humidity, and temperature sensor components are designed with CMOSens technology, which offers a complete sensor system on a single chip, including the sensing elements, analog, and digital signal processing, a/d converter, calibration, and data memory as well as a digital communication interface supporting the I2C standard mode. The main application for the SVM30 sensor combo module is air purifiers, but it is also optimally suited for HVAC and other appliance products. Learn more, download the SVM30 datasheet.
