Reflective Infrared IR Optical Sensor with 470 and 10K ...

This Reflective IR Sensor is a simple plastic casing with two elements - an IR LED and an IR phototransistor. You can control the IR LED and turn it on to bounce IR off objects to determine their reflectivity. White & light colored stuff will bounce the light, so you can detect it. Black & dark colored stuff will absorb the IR light so that it isn't detected. Likewise, if something isn't in ...

How to build an IR Sensor » maxEmbedded

The sensors used in them are based on reflective/non-reflective indirect incidence. The IR LED emits IR radiation, which in normal state gets reflected back to the module from the white surface around the black line, which gets incident on the photodiode. But, as soon as the IR radiation falls on the black line, the IR radiation gets absorbed completely by the black color, and hence there is ...

Infrared Sensor - How it Works, Types, Applications ...

These type of sensors use object as IR source/ transmitter. Object radiates energy and it is detected by IR receivers. A Signal processor is then used to interpret the signal to fetch information required. Example of Passive IR Sensor: Thermocouple-Thermopile, Bolometer, Pyro-Electric Detector, etc. Fig. 4 – Passive Infrared Sensor. There are two types of Passive Infrared Sensor: Thermal ...

Understanding Active & Passive Infrared Sensors (PIR) and ...

· Active IR Sensors. Fig 3: An IR receiver detects a reflected signal from a hand to turn off the LED. While PIR sensors are excellent if you want to detect general movement, they don’t give you any more information on your subject. To know more, you’ll need an active IR sensor. Setting up an active IR sensor requires both an emitter and ...
