| Program Name | agent_sun |
| Agent Name | sun |
| File | agent_sun.cpp |
| Hardware | OPT3001 I2C Sun Sensor |
Description
The sun sensor agent (aka agent_sun) is an agent that handles operations with the sun sensors. This includes initialization, configuration, and reading values from the sun sensors. Nothing is done with the values obtained from the sun sensors, but they are available for use elsewhere, such as in an ADCS agent (not included).
There are six sun sensors, with one located on each faces of the cubesat.
