Description

The set includes a pair - transmitter and receiver of light from the IR range with a wavelength of 940 nm. The transmitter's system should include sequentially, the resistor limiting the current up to 50 mA. The emitter assembled this way, sends a signal which is received through the detector in the form of the NPN phototransistor with the resistor  pulling-up the output to the supply voltage. Example of wiring and maintenance can be found in the diagram or in the video below.

 

 

Systems can be used as a simple, reflective distance sensors with analog output, connected for example to a module of Arduino Uno.

 

The transmitter was highlighted with the yellow dot in the upper part of the system, receiver with the red dot.
