This Kit contains with 3pcs of digital sensor module, which can be independently enabled / disabled, which can measure not only the temperature humidity, but also the pressure. The BME280 sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI! For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI. Our BME280 Sensor 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 good, you can also use it as an altimeter with ±1 meter accuracy. BME280 Atmospheric Pressure Sensor Temperature Humidity Sensor Breakout for Arduino Package： 4pcs BME280 Atmospheric Pressure Sensor Temperature Humidity Sensor Breakout

Description:

BME280, the precision sensor from Bosch, is soldered onto PCB. Not only the pressure and the temperature, this sensor can measure humidity.

It uses both I2C and SPI (supports 3-, 4-wire SPI) interface

Make sure to put SDO to high to get address 0x77. This will work with Adafruit BME280 library perfectly.
