IR (Infrared) Obstacle Detection Sensor Circuit

Feb 02, 2015· 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.

Sensor Wiki: KY-026 Flame IR Sensor - The Geek Pub

The KY-026 flame IR sensor is packed with a photo diode that is sensitive to the spectral range of light that is created by an open flame. The flame sensor detects wavelengths ranging from 760nm to 1100nm in the infrared spectrum. After detecting a flame, the digital out (DO) line will become HIGH.. The analog out (AO) will provide a direct measurement of the reading.

IR Probe - Duet3D

IR Probe. A differential modulated IR height sensor. The sensor detects the target height by looking for the reflected light from two separate LEDs to be equal. The two LEDs are positioned such that they reflect light into the sensor at slightly different heights. This allows the sensor to be used on most bed surfaces.

IR Tracking Sensor Module - Wiki

The IR emission tube of TCRT5000 sensor constantly emits infrared light. Since the black absorbs light, when the IR emission tube shines on a black surface, the reflected light is less and so less IR rays are received by the receiving tube. It indicates the resistance is large; then the comparator outputs high and the indicator LED goes out.
