Product Features
- BME280 is a Temperature, Humidity & Pressure Sensor breakout board.
- Supply voltage VDD main supply voltage range: 1.71 V to 3.6 V
- BME280 is a precision sensor, is soldered onto PCB. It uses both I2C and SPI (supports 3-, 4-wire SPI) interface. Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz).
- Pressure: 300-1100 hPa; Temperature: -40 to +85C; Humidity: 0-100%.
- This precision sensor is used for measuring barometric pressure with 1 hPa absolute accuraccy, and temperature with 1.0C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with 1 meter accuracy.
