ABSTRACT: In recent years, there has been a substantial increase in the demand for intelligent and reliable motion detection systems insecurity, automation and surveillance. Conventional motion detectors that are based on Passive Infrared (PIR) sensors typically face drawbacks such as false alarms, inability to identify movement from non-living matter and bestowing no remote access. A Smart Motion detection system using a Esp32 microcontroller unit and HC-SR04 ultrasonic sensor is proposed to overcomes issues faced by conventional motion detection systems. The system measures the changes in distance to detect motion from both living matters and non-living. It generates alerts in two forms, local alert using a led and buzzer and an IoT based alert using on a web interface with a telegram bot API. Further, the system will record the last five instances of motion along with timestamps as a way to monitor events in the short term. The proposed model gives evidence for good success in the field, as responded timely, rarely faulty and cost effective. The modular setup makes it suitable for use in private homes, office and industrial security protocols, and cannot with future applications in AI and cloud systems.
