veritable BM2280 (mai 2019)

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

arnaque au BMP280 vs BME280

https://goughlui.com/2018/08/05/note-bosch-sensortec-bmp280-vs-bme280-sensor-confusion/

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
