Implementasi Keamanan Ruangan Berbasis IoT dengan Sensor PIR, Telegram, dan Peringatan Suara

Home security is crucial for protecting property and occupant safety. Conventional technology often falls short in providing optimal protection. With advancements in the Internet of Things (IoT), smarter and more affordable security solutions are now accessible. This research develops an IoT-based room security system using a PIR sensor to detect motion, Telegram notifications for real-time communication, and sound alerts as preventive measures. The NodeMCU ESP8266 module processes data from the PIR sensor and transmits signals via WiFi. Test results show that the PIR sensor successfully detects motion up to 5 meters with a 93.33% success rate. The system also effectively sends real-time notifications to the Telegram app and provides efficient sound alerts. Thus, this system significantly enhances home security with minimal cost and complexity, offering convenience and quick response to users.
