Project Overview

Dark winter months in northern climates often limit plant growth due to insufficient solar radiation. This project combines a custom lighting controller with bespoke LED PCBs engineered specifically for indoor plants.

By calculating solar position angles and polling an onboard ambient light sensor, the controller dynamic-dims the LED array to smoothly mirror natural sunrise, midday intensity, and sunset curves.
