Sensors Detectors: Human Proximity Detectors Circuits Motion Detector Alarm This motion detector alarm circuit can detect a moving person from a distance of 1 meter. it uses a Dual IR Transmitter Receiver module HOA1405. When the sensor detects the reflected IR rays, Alarm will sound for 2 minutes. The circuit can be modified for various applications including AC operated alarm systems. Build Your Own Metal Detector with an Arduino Projects For this metal detector project, we will be using an Arduino to process the oscillation signal instead of offsetting the oscillation with a second tank circuit. The Arduino will store the fixed frequency and continuously compare the incoming frequency of the detector circuit with the stored frequency (more on the Arduino program below). Simple Metal Detector Circuit Diagram using 555 Timer IC There are so many metal detector designs but most of them are complex in design so here we are going to design a simple metal detector circuit using 555 Timer IC. Before going further we need to understand concept of inductor and RLC circuits.
