IR (Infrared) Obstacle Detection Sensor Circuit

· Infrared receivers are also called as infrared sensors as they detect the radiation from an IR transmitter. IR receivers come in the form of photodiodes and phototransistors. Infrared Photodiodes are different from normal photo diodes as they detect only infrared radiation. The picture of a typical IR receiver or a photodiode is shown below. Different types of IR receivers exist based on the ...

Using IR & Hall Type Sensors for Train Detection - Arduino ...

However, infrared sensors have many problems with false triggering. On video presents the DIY IR module that solves these problems. But the lights detection and IR detection sensors have one more problem - they are very large, and it is hard hidden them into the rail track. Therefore I prefer the Hall sensor. A Hall effect sensor . In comparison with other sensors, the Hall sensor has the ...

Infrared Sensors Overview: Types, Functioning and Use ...

The sensor in the PIR motion detector consists of two halves because its purpose is not only to detect infrared waves but also to indicate a change as a signal for motion. The sensor is idle when there is no motion in the detection field. However, when a person or another living thing that radiates heat, such as an animal passes in the field range, it produces a positive differential change in ...

IR model railroad train detectors, infrared proximity sensors

Coded pulsed infrared proximity sensors for detecting model trains on the track. Pulsing (modulation) allows the detector to ignore ambient lighting. Coded pulsing allows each detector to ignore the IR signals of other nearby detectors. May be used as a reflective detector (sensors in the roadbed) or as an interrupt detector (detector looks across the track). Sensors can be used with the room ...
