BME 280 Barometric Pressure + Temperature + Humidity Sensor
Bosch has stepped up their game with their new BME280 sensor, an environmental sensor with temperature, barometric pressure┬áand┬áhumidity! This sensor is great for all sorts of weather/environmental sensing and can even be used in both I2C and SPI!
This precision sensor from Bosch is the best low-cost sensing solution for measuring humidity with ┬▒3% accuracy, barometric pressure with ┬▒1 hPa absolute accuracy, and temperature with ┬▒1.0┬░C accuracy. Because pressure changes with altitude and the pressure measurements are so good, you can also use it as an altimeter with┬á ┬▒1 meter accuracy!
Supports I2C and SPI interface.
Barometric Pressure absolute accuracy: ┬▒1hPa
Temperature accuracy: ┬▒1.0┬░C
Power consumption: ┬▒2.7uA
Supply Voltage: 1.71V ~ 3.6V
Using barometric pressure, altitude can be calculated within ┬▒1m accuracy.
