Sensors play an increasingly important role in today's advanced world. The Exploring Sensors module allows students to explore the different uses of mechanical and electronic sensors from a security applications viewpoint.

Students are introduced to the variety and characteristics of sensors. They build a variety of circuits using magnetic sensors, vibration/shock sensors, pulsed infrared sensors, and motion sensors. Students also build alarm circuits using sensors, an electromechanical relay, and a buzzer.

Sensors in this module include an infrared photoelectric beam sensor, an infrared motion detector, a mechanical switch, a vibration detector, and magnetic proximity sensors.
