Abstract

The rapid development in Indonesian demands better infrastructure development. One of the priorities is the construction and repair of public roads to support the increasingly high mobility of the community due to the rapid development of transportation technology. One of the most needed road equipment is public street lamp lighting. With the implementation Smart Street Light based on internet of things can reduce the use of electrical energy accompanied by real (QoS) applications and services of Quality of Service on the network because Smart Street Light uses an automation system by utilizing a microcontroller. ESP32 as the control center, LDR sensor as light detector, Infrared Transmitter (IR Emitting) sensor and Infrared Receiver (IR Receiver) sensor as object detector. In daytime conditions, the light will turn off when the LDR sensor does not detect the intensity of light from the sun. On the other hand, when the LDR sensor does not detect the intensity of sunlight, all light will turn on dimly. Then at night when the IR1 sensor detects an object, lamp 1 will light up brightly and the IR2 sensor detects an object, lamp 2 will light up brightly and lamp 1 will return to dim, so on at lights 3-5. Methodology Prototype consists of several stages, namely: Hardware and software design, system testing, system analysis. The prototype of smart street light light can adjust the level of dim or bright lights automatically based on traffic situations and conditions. After testing the sensor 10 times, it is known that the results of the sensor accuracy are quite good, this refers to the serial monitor display when the IR sensor detects an object with a distance of 5 cm, the serial monitor will display a small number, namely 0. Conversely, if the IR sensor test detects an object with a distance of more than 5 - 20 cm, the serial monitor will display the numbers 20-2700. The LED light will light up brightly if the object is 5 cm away, and will dim if the object is more than 5-20 cm away. The results of the QoS (Quality of Services) test show that the throughput with index typhoon 0 is 46 kbps. Packet loss with index typhoon 4 is worth 0%. Delay with index typhoon 4 is worth 34.93 ms. Keywords: ESP32 Microcontroller, Automatic, Realtime, LDR Sensor, (Infrared Transmitter, Receiver), Smart Street Light, QoS.
