## Description

Ideal for automating the orientation of solar panels, this module tracks the light source using two probes and the shadow principle, controlling the motor clockwise or counterclockwise until the lighting is balanced. It is mounted directly on the board, the motor is powered separately, includes a delay to reduce vibrations, operates at 5-5.5V DC with consumption below 1.5A, 15 cm probe cable.
Light tracking module (solar light and more), ideal for solar panel projects for their automation.
The operating principle is based on the shadow generated by the two sensors, the module trying to find a balance where both sensors receive the maximum amount of light.
The module drives the motor (recommended with gears) clockwise and counterclockwise until the two sensors are equalized. The motor is attached directly to the board, powered separately (not directly from the solar panels). If the motor does not rotate in the desired direction, reverse the polarity.
A small delay is incorporated to prevent vibrations and constant direction changes.
