This Arduino-compatible shield allows the evaluation of the Bosch Sensortec BME280 combined temperature, humidity and pressure sensor. With a single jumper it can be configured for I²C or SPI mode, but it can also be configured by the host. A user LED is available for visual feedback. Together with a Arduino/Genuino 101 board and the dedicated Android app the data can be monitored over Bluetooth Low Energy (BLE). The app also displays accelerometer and gyroscope data from the Genuino 101 and allows the user to control digital outputs and read analog inputs.
