The paper describes the design and creation of a smart IoT alarm system based on an ESP32 microcontroller. The system uses an ultrasonic sensor HC-SR04 for motion detection and a magnetic Reed Switch sensor for door opening monitoring. A piezo buzzer and two LEDs (green and red) are used as actuators. Alarms are sent in real-time to a mobile device via the Blynk IoT platform. The possibility of remotely turning on and off the alarm from a mobile phone has also been implemented.
