Abstract

Rats are rodents that often cause harm, especially at home and in industrial environments. The losses caused include disgusting behavior, health problems and equipment damage. The use of a mouse detection device that utilizes ultrasonic waves and motion sensors can detect the presence of mice. This detection tool can be used as a method to control the rat population. Mice have a hearing range ranging from 5 KHz to 60 KHz. This frequency range can cause mice discomfort. Other efforts made using toxic chemicals are considered less consistent and pose risks to the ecosystem. This research developed a system that detects the movement of mice and emits ultrasonic sounds to chase them away. Using a PIR sensor, the system detects mice and activates ultrasonic sound. Accuracy tests ensure the sensor only responds to mouse movements. The design process involves electronic components and ultrasonic sound settings. Trials show this system is accurate and effective in repelling mice. This research involves a rat detection system using three PIR sensor points. The PIR sensor was tested and proven to function properly, producing an output of 1 for detecting movement and 0 for no movement. The system test results show that the speakers used produce PWM output in the frequency range of 15 kHz to 50 kHz, with average values of 20 kHz and 40 kHz, according to the design. Tests using mice as objects showed that mice were disturbed by ultrasonic sound, especially at an average frequency of >20 kHz when the sensor detected the presence of mice.
