By Sensirion 34
Sensirion's 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 CO2 equivalent signal (CO2eq) with a single sensor chip. The SVM30 further offers calibrated air quality output signals as well as compensation of humidity cross-sensitivity. The sensing element features unmatched robustness against contamination by siloxanes present in real-world applications enabling unique long-term stability and low drift.
The humidity and temperature sensor on SVM30 covers a humidity measurement range of 0% RH to 100% RH and a temperature measurement range of -20°C to +85°C with a typical accuracy of ±5% RH and ±1°C.
The gas and RH/T sensor components are designed with Sensirion’s 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.
