Infrared Transmitter IR Transmit Sensor Module for Electronic Brick AVR PIC

Infrared emission control, also known as infrared emitting diode, it belongs to two Tube can be directly converted into electrical energy near-infrared light and a light emitting device can radiate out, its structure, with the general principle of the light emitting diode similar, but with a semiconductor Different materials;

The infrared receiver is set to receive, amplify, demodulate one of the devices, which has been completed within the demodulation IC output is a digital signal;

The principle of infrared communication.Let’s look at the structure of the infrared receiver: infrared receiver inside there are two important elements, namely the IC and PD. IC is a receiver processing elements, mainly composed of silicon crystals and circuits, is a highly integrated device, the main To function as a filter, shaping, decoding, zoom and other functions. Photodiode PD is, the main function is to receive the optical signal Number.

Transmit 38KHz modulating signal

All pins are standard 0.1″ spaced

Pin Connector to board : 3 Pins
