Sensirion said it now offers the ultralower-power SGPC3 gas sensor. The SGPC3 makes indoor air quality sensing available for mobile and battery-driven applications. With an average supply current of less than 0.07 mA the SGPC3 is able to provide indoor air-quality measurements with several years of battery lifetime. Based on Sensirion’s SGP multi-pixel platform the SGPC3 offers a complete gas sensor system integrated into a small 2.45 x 2.45 x 0.9-mm 3 DFN package featuring an I2C interface and a fully calibrated and humidity-compensated air quality output signal.
Sensirion’s MOXSens technology provides the SGPC3 with robustness against contamination by siloxanes resulting in long-term stability and accuracy. The combination of ultralow power consumption and long-term stability makes the SGPC3 a suitable choice for indoor air-quality monitoring in mobile and battery-driven smart-home applications. Evaluation and testing is supported by application notes and sample code; the SGP evaluation kits are also available through Sensirion’s distribution network.
