This is a breakout board with a Bosch BMP-280 combined temperature and barometric pressure sensor, mounted with all components necessary to connect to a Arduino, Pi, ESP8266 or other micro-controler via a simple I2C or SPI interface.
This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring 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 ±1 meter accuracy.
