RANCANG BANGUN SISTEM MONITORING SUHU DAN KELEMBABAN BERBASIS ARDUINO UNO UNTUK SMART HOME

Abstract

This research aims to design and build a room temperature and humidity monitoring system based on
the Arduino Uno microcontroller that can be applied to smart homes. This system uses a DHT11
sensor to read ambient temperature and humidity, then displays the data on a 16x2 LCD and sends
the data to the user's smartphone via the HC-05 Bluetooth module. Test results show that the system
can read temperature with an accuracy of ±1°C and humidity of ±5% RH. The system successfully
operated stably for 72 hours of continuous testing with an average power consumption of 0.5 watts.
This system implementation can help homeowners monitor environmental conditions in real time for
comfort and energy efficiency.
