Datasheet SVM30 Multi-gas, humidity and temperature sensor combo module Measures indoor air quality parameters total VOC (tVOC), CO -equivalent (CO2eq), relative humidity RH and 2 temperature T Automatic baseline compensation and humidity compensation of MOX gas sensor Outstanding long-term stability and reliability Fully factory calibrated and tested Digital I2C interface 5V supply voltage Dimensions: 39 x 15 x 6.5 mm Product Summary The SVM30 is a Multi-gas, humidity and temperature sensor combo module containing an SGP30 gas sensor as well as an SHTC1 humidity and temperature sensor. The SGP30 gas sensor on the SVM30 combines multiple metal-oxide sensing elements the pixels on one chip, thereby offering the possibility to measure a total VOC signal (tVOC) and a CO equivalent signal (CO eq) 2 2 with one single sensor-chip. The SVM30 further offers calibrated air quality output signals as well as compensation of humidity cross-sensitivity. The sensing element features an unmatched robustness against contamination by siloxanes present in real-world applications enabling a unique long-term stability and low drift. The humidity and temperature sensor on SVM30 covers a humidity measurement range of 0 to 100 %RH and a temperature measurement range of 20 to 85 C with a typical accuracy of 5 %RH and 1C. The gas and RH/T sensor components are designed with Sensirions CMOSens technology. This technology 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 and a digital communication interface supporting I2C standard mode. Sensirions state-of-the-art production process, including full calibration and testing of the sensors, guarantees high reproducibility and reliability.
