Bosch has stepped up their game with their new BME280 Atmospheric Sensor, an environmental sensor with temperature, barometric pressure, and humidity! 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 1.0C 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!
Supports I2C and SPI interface.
Barometric Pressure absolute accuracy: 1hPa
Temperature accuracy: 1.0C
Power consumption: 2.7uA
Supply Voltage: 1.71V ~ 3.6V
Using barometric pressure, altitude can be calculated within 1m accuracy.
