Development of Home Security System Using Motion Sensor and Magnetic Sensor with ESP-32 Cam Based on Telegram

A home security system is very important for the comfort of home residents in terms of securing valuables. Security using conventional locks alone is not enough. This tool uses a motion sensor and magnetic sensor and ESP32-Cam. The research design uses the ADDIE development model and uses experimental methods. From the results of the motion sensor measurements, the motion sensor works at a distance of 1-7 meters, but at a distance of 6-7 meters the response speed of the motion sensor slows down and it can take pictures if the motion sensordetects movementwhilethemagneticsensorThenew2.3 cm can detectopen doors and can send notification messages to Telegram, but access to streaming can be accessed at any time.
