The Accel SPI Board enables you to measure acceleration with a complete 3-axis acceleration tool ADXL345 provided on-board. This tool measures static, as well as dynamic acceleration resulting from motion or shock.
The SHT1X Board features the SHT11 sensor. It is connected to a development board through a 2-wire serial interface, thus enabling you to measure temperature and humidity.
Note: not recommended for new design.
