IR (Infrared) Obstacle Detection Sensor Circuit

2015-02-02· An IR sensor consists of an IR LED and an IR Photodiode; together they are called as Photo – Coupler or Opto – Coupler. When the IR transmitter emits radiation, it reaches the object and some of the radiation reflects back to the IR receiver. Based on the intensity of the reception by the IR receiver, the output of the sensor is defined.

What are Infrared Emitters, Receivers and Repeaters?

It operates by adding the IR signal to existing AC signals on the cable along with a DC voltage offset for power. For this system to work, users will need a minimum of one signal injector at the IR receiver source and a coupler at the emitter end. The injector combines the IR remote signal with any AC TV signal already present on the coaxial cable line while leaving the TV portion of the ...

HiTechnic NXT IRSeeker V2 – Modern Robotics Inc

Modulated (AC) Mode – The sensor will detect modulated IR signals such as those from the HiTechnic IRBall or some IR remote controls. In Modulated mode, the sensor will filter out most other IR signals to decrease interference from lights and the sunshine for example. The sensor is tuned to square wave signals at 1200Hz. Un-modulated (DC) Mode – The sensor will detect unmodulated IR ...

Passive infrared sensor - Wikipedia

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give information on who or what moved. For that purpose, an ...
