Blackbody is a set of sensor boards for measuring the irradiance and temperature of various parts of the solar array on the car. There are currently three variants: Blackbody A, Blackbody B, and Blackbody C.
Blackbody A measures both light sensors (TSL2591) and temperature sensors (PT100 RTDs). This board is installed into the solar vehicle for data collection and informing the operation of Sunscatter.
Blackbody B manages a sole light sensor (TSL2591). It is primarily used for testing and normalization of solar cell/module/array results. It talks to the PV Curve Tracer.
Blackbody C is a breakout board of the light sensor (TSL2591) optimized for placement on the topshell of the solar vehicle. This board talks to Blackbody A during the race.
