Prototipe Sistem Kendali Cerdas Kanopi Rumah Berdasarkan Parameter Cuaca Berbasis Mikrokontroler

Abstract

Unpredictable weather conditions can hinder the clothes-drying process, thus requiring an automatic canopy control system based on real-time weather conditions. This study aims to design a microcontroller-based automatic canopy control system prototype using two transmitters and one receiver communicating via the NRF24L01 PA+LNA module. Each transmitter employs a BH1750 light sensor, an FC-37 rain sensor, and an anemometer to detect light intensity, rainfall, and wind speed, while the receiver controls a DC motor through a BTS7960 driver with a limit switch serving as the canopy position limiter. The test results show that the light sensor achieved an accuracy of 87.08%–99.4%, the rain sensor reached 100% reliability, and the wind speed sensor achieved an accuracy of 90%–100%. In the overall system testing, the transmitter sent signal codes based on a combination of bright, non-rainy, and low-wind conditions with a 100% success rate. The canopy automatically opens when both transmitters send signal 1, and closes when either transmitter sends signal 0. These results demonstrate that the prototype operates accurately, consistently, and responsively to changing weather conditions
