CSLS: Design Of Security Lighting Systems For Pedestrians As Part Of Smart City

Serious crimes, such as robbery, assault, and beatings, generally occurred at night. Therefore, people’s concern about crime at night is increasing. Some pedestrians may still feel that the existing lighting levels are insufficient. We propose a CSLS (Connected Security Lighting System) system by utilizing ESP32 communication technology, LDR Sensors, and Passive Infrared Sensors to reduce pedestrian fear of crime at night. This CSLS system can turn on lights with 0 to 100% brightness in various conditions starting from bright, dim, and off. LDR and PIR sensor values are constantly changing according to the surrounding conditions, with a range of readings per 1 second. With this CSLS system, the energy consumption of lamps will be more efficient, provide pedestrians security and reduce crime rates at night.
