BME280 DIGITAL SENSOR

BME280 DIGITAL SENSOR

  • R 150.00


Description:

BME280, the precision sensor is soldered onto PCB.
Not only the pressure and the temperature, this sensor can measure humidity; Humidity sensor and pressure sensor can be independently enabled / disabled.
It uses both I2C (up to 3.4MHz) and SPI (supports 3 and 4 wire SPI) interface.
Current consumption 1.8 µA @ 1 Hz humidity and temperature.
Supply voltage VDD main supply voltage range: 1.71 V to 3.6 V ; VDDIO interface voltage range: 1.2 V to 3.6 V
2.8 µA @ 1 Hz pressure and temperature
3.6 µA @ 1 Hz humidity, pressure and temperature
0.1 µA in sleep mode
Operating range -40...+85 °C, 0...100 % rel. humidity, 300...1100 hPa
