100% brand new and high quality BME280, the precision sensor from Bosch, is soldered onto PCB. Not only the pressure and the temperature, this sensor can measure humidity. It uses both I2C and SPI (supports 3-, 4-wire SPI) interface Specifications: Supply Voltage: 1.8 - 5V DC Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz) Operational Range: Temperature: -40 to +85°C Humidity: 0-100% Pressure: 300-1100 hPa Resolution: Temperature: 0.01°C Humidity: 0.008% Pressure: 0.18Pa Accuracy: Temperature: +-1°C Humidity: +-3% Pressure: +-1Pa I2C address SDO LOW : 0x76 SDO HIGH: 0x77

chip you have send me are not BME280 but BMP280 , there is no humidity available (chip id is 0x58 instead 0x60) the marking on the chip begin with K as written on BMP280 datasheet Page 41. so i ask refund of the order or sending me 3 reals BME280 with marking U as written on BME280 datasheet Page 44. regards
