Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI
This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuraccy, 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 ±1 meter accuracy
Features
- Pressure range: 300 ~ 1100hPa (altitude 9000 m ~ -500 m);
- Working voltage: 1.71 – 3.6VDC;
- Low power consumption: 4μA;
- High precision: at low-power mode, the resolution is 0.06hPa (0.5 meters);
- Temperature output;
- Communication interface: I2C or SPI;
