Rancang Bangun Sistem Monitoring dan Kontrol Lampu, Kipas Angin Menggunakan Sensor Gesture Berbasis Internet of Things (Iot)

Abstract

Research on monitoring and control systems for lamps, fans using gesture sensors based on the Internet of Things (IoT) uses Gesture sensor components, DS18B20 temperature sensors, BH1750 light sensors, lamps, relays, fans and ESP8266 Microcontrollers. Lamps and fans will be on using Blynk when there is movement detected by Gesture with the provisions, lamps on if the light intensity is smaller than 300 lux and off if the light intensity is greater than 300 lux while the fan will be on with 3 types of speed based on the room temperature value, namely 30-32C relay 1 on low fan rotation speed, 33-35C relay 2 on medium fan rotation speed and 36-38C relay 3 on high fan rotation speed. In addition, lamps and fans can be turned on and off remotely using a smartphone. Based on the research results obtained the highest current measurement results at a high fan rotation speed of 0.14 A, and the current decreases when the fan rotation speed drops, the measurement of light intensity and room temperature each has an error of 6.3% and 4.77%. The purpose of this research is to create a monitoring and control system for lamps and fans automatically and remotely using a smartphone.
