Designing a prototype of an appropriate tool can serve as a crucial example of science, technology, engineering, the arts and mathematics (STEAM) education for students. In this article is presented a prototype of a passive infrared (PIR) waterproof doorbell motion sensor as such an example. The PIR sensor is an electronic sensor that gives a signal when its rays are crossed. It measures the infrared (IR) light radiating from the objects within its field of view and can detect a change in motion in its surroundings within a different range of radius, hence it is most often used in motion detectors. This type of sensor is most commonly used in security alarms and automatic lighting applications. It detects general movement, but does not give information about the person or object that has moved. The developed prototype of a waterproof doorbell motion sensor detects motion within its range, around five meters, of an unusual motion. Using this sensor, electrical power consumption can be minimised, making it an efficient and low-cost device, thus making it a particularly suitable tool for educational purposes © 2022. WIETE
