RF430FRL152HEVM through the TRF7970AEVM and plots it on the graphs in the PC GUI.

with a finger to affect the temperature result. The light sensor and the thermistor locations on the EVM
are shown in
The thermistor temperature measurement may not reach the true skin temperature, because some of
the heat dissipates into the EVM.
The light sensor reading value does not increase in the presence of extra light (for example, if you
shine a flashlight on it), because of design reasons with the light sensor selected for this EVM.
However, the light sensor shows a change for reduced light. Note that the light sensor on the Sensor
Hub BoosterPack does not have this same limitation.
