Setup of Demo System
The following sections describe how to setup a demo with and without the Sensor Hub BoosterPack, and
also for custom configuring and operation of the device.
5.1
Set up the RF430FRL152HEVM With Sensor Hub Demo Using the PC
This section describes how to setup and run the Sensor Hub BoosterPack demo. With this setup, the
RF430FRL152HEVM samples over I
2
C three different sensors on the SensorHub BoosterPack. They are
temperature and humidity (SHT21) and a light sensor (ISL29023). After collecting the samples, the data is
transmitted over RF to the TRF7970AEVM which reports them to the PC application. Finally the results
are plotted on the graphs.
1. Connect the TRF7970AEVM to the PC with a USB cable.
2. On the RF430FRL152HEVM, use a pencil or pen to position the switches as shown in

3. Attach the Sensor Hub BoosterPack on top of the RF430FRL152HEVM. Make sure that the orientation
is correct (see
4. Connect the RF430FRL152HEVM to the PC using the provided USB cable. Note that this USB
connection is only for the power supply, and no data is passed through it.
5. Position the RF430FRL152HEVM antenna on the antenna portion of the TRF7970AEVM as shown in
. It is recommended to have an insulator between the two antennas or to hold them at a
distance from each other to prevent any short circuits.
