BME680 multi-functional 4in1 environmental sensor - SPI / I2C - DFRobot SEN0375

MultifunctionalMEMS4in1environmental sensor manufactured by DFRobot. It has an embeddedBME680chip. The module is a combination of volatile organic compounds(VOC) sensor,temperaturesensor,humiditysensor andbarometer. It is used as a component forair qualitymonitoring, and is widely used in environmental monitoring, home automation and control, orGPS improvements. The use of MEMS technology and BME680 chip makes the sensor small in size andlow in power consumption. The measuring range for temperature is-40°C to 85°Cwith an accuracy of +/- 1°C; for humidity -0% to 100% RHwith an accuracy of +/- 3% RH; for atmospheric pressure -300 hPa to 1100 hPa with a measurement accuracy of +/- 0.6 hPa.
