3 Introduction The CuSP platform is a small, wireless, low powered sensor that measures incident illuminance along with static and dynamic motion angle parameters. The following are the core design requirements:-. RGBY sensing at 0-0Hz.. Sensor orientation sensing.. Able to communicate to a hub in room. (Data rate: 0-00Hz). Low powered. Must run for longer than hrs on coin cell battery. The following are the nice-to-have s for the second version. On board pluggable camera module.. Controlable field of view by using optics.. Integrated VLC transceiver. The following document gives a basic overview of the CuSP platform.

4 Components The current version of the platform has the following components on board:-. MSP0F9: Microcontroller. TCS: Taos Color Sensor. TCS: Taos Color Sensor. ADJD-S-CR999: Avago Color Sensor. ADXL: -Axial Digital Accelerometer. ITG-00: -Axial Digital Gyroscope. ANTTSMIB: ANT AT RF Transceiver Drop-in Module The Microcontroller is responsible for scheduling and execution of tasks like data acquisition from the sensors, data processing and set up transmission over RF to a receiver. The color sensors on board measure light intensities over channels - Red, Green, Blue and Clear. After evaluating performance, one will be selected for the next revision while the other two will be discarded. Data from the -axis accelerometer is used to compute the static orientation of the platform. Data from -axis gyroscope is used to compute the orientation of the platform when under motion. the ANT RF module is used to transmit data and receive commands from a service running on an ANT enabled computer. The following subsections highlight relevant information about the components. In-depth details can be found in their respective datasheets..
