<![CDATA[Garage system automation has become essential to enhance security and energy efficiency. This study aims to design and implement a prototype of a lighting and garage door control system based on the NodeMCU ESP8266 integrated with the Blynk application. The research method includes hardware design using ultrasonic and PIR sensors, as well as software development based on the Internet of Things. System testing was conducted using black-box testing to verify system functionality and delay testing to measure response time. The results show that the ultrasonic sensor can detect objects up to 20 cm, while the PIR sensor detects motion up to 53 cm, with a relatively fast and stable system response, achieving an average error rate of 3.54% for the ultrasonic sensor. The system is capable of activating lights, opening the garage door using a servo motor, and sending real-time notifications. Therefore, the developed system is proven effective in improving security and energy efficiency, as well as enabling remote control.Keywords: Automatic control; Internet of Things; NodeMCU ESP8266; PIR sensor; Ultrasonic sensorAbstrakOtomatisasi sistem garasi menjadi kebutuhan penting dalam meningkatkan aspek keamanan dan efisiensi energi.
