eZ430-RF2500 is preloaded with a wireless temperature sensor network firmware and may be
reprogrammed at any time. This network consists of an Access Point that measures its own temperature
and also wirelessly receives temperature measurements from End Devices. End Devices measure their
temperature once per second and then enter a low-power mode to reduce battery usage. The Access
Point transmits all measured data to the PC through the UART backchannel. The included PC Sensor
Monitor Visualizer provides a demonstration of the eZ430-RF2500 using the SimpliciTI protocol across a
star network. In the PC Sensor Monitor Visualizer, the center node is the Access Point and the attached
bubbles are the End Devices. The PC application displays the temperature of both the End Devices and
Access Point. Additionally, the PC application is capable of simulating distance from its access point when
the End Devices are moved. The number of End Devices can be expanded by adding more target boards
in the star network as seen in
