Arduino BMP280 BMP180 3.3V Digital Barometric Pressure Sensor Module

Package includes: 1x BMP280 I2C Digital Barometric Pressure Sensor Module For Arduino (upgrade version of BMP180)

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

Note: You need to add 5V to 3.3V level converter circuit between Arduino UNO R3 and the module.
