BME280 3.3V High Precision Atmospheric Pressure, Temperature, humidity Sensor Module

BME280 is a high-precision, small-volume, low-energy pressure sensor that can be used in mobile devices. Its performance is excellent, the absolute accuracy can be as low as 0.2Pa, and the power consumption is very low, only 2.7uA. The BMP280 uses a powerful 8-pin ceramic leadless chip in a thin carrier (LCC) package, which can be directly connected to various microprocessors through I2C and SPI buses.
