You can also control the solar street light to keep 100% brightness for 4 hours after dark. For the rest of the night, set the light keep full brightness when motion is detected, and reduce it to 30% when there is no presence is detected after 30s hold time. Various working modes are achievable by adjusting the setting of Smart-Unit.
The system uses sensors such as LDR and PIF to detect light and human presence, which is transmitted wirelessly to the controller. This data is used to turn on/off or dim the street lights accordingly. The proposed system offers a solution for efficient monitoring and control of street lights, resulting in significant energy savings.
Using sensors and microcontrollers to automatically control street lights has been shown in previous studies to help save energy. The goal of the proposed system is to speed up repairs for individual faults, reduce delays that could last for days or months, reduce energy consumption, and improve maintenance of street lighting.

Solar street lamps are powered by solar PV panels and are generally mounted on a pole-like structure. The solar powered LED lights work on the principle of converting solar energy that is absorbed by photovoltaic cells into electrical form of energy. This form of energy is used to charge the battery that will supply power to the street lights.
The solar street light is a lighting system powered by electricity from batteries, which are charged with the use of solar panels. The solar panel consists of crystalline cells. The charge controller ensures the safety of the system, avoiding overcharging or discharging the battery.
This paper investigates controlling the street lights from one controller that uses Solar PV energy stored in a battery and the grid as a backup source. The source provided can supply power to all three streetlights from one supply instead of multiple power supplies and controllers. Furthermore, it is also possible to dim the street lights.
