This package of 4 sensors was just what I was looking for to add environmental sampling to some of my Raspberry PIs. With a little bit of soldering, some breadboard jumper wires and a bit of Python code I had my PIs delivering periodic environment data to my MQTT server for use by the Homebridge to supply info the Home app on my phone. This all started when we wanted to monitor and control the temperature in the garden potting shed.

Product Description
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.
