Telecomando Rele Por Ir Infrarrojo Smart Aprende Codigo 5v Itytarg

Learning IR remote control switch, as the name implies, the microcontroller can remember a button on the remote control key data, it controls the relay switch, by learning again, you can modify key data storage, for example, you use the remote control for this "8" learning key, you can use after the success of "8" to do the control buttons, power-down data is not lost, if you want to use the key "9" as the control, you need to re-learn the microcontroller will make changes.

Module for use:
1. Power supply, wiring is correct LED indicator light, 5 seconds after the module to work correctly, the relay work simultaneously!
2. Each time you press the button at S1, the relay switches with working conditions, on or off, while the indicator lights on or off!
3. Infrared remote learning success, every success in learning remote control is pressed once (remote learning at the bottom), the relay switches with working conditions, on or off, while the indicator lights on or off!

Learning how to operate the remote control method has two kinds:
1. Hold down the S1 button for 5 seconds or more, indicator LED1 is lit, that enter the learning state, and then release the button S1, and then press the remote control button, LED long flashes to indicate that learning has been successful!
2. Infrared receiver with the remote control at the module, press any key on the remote control 10 seconds, the indicator LED1 lit, it indicates to enter the learning state, and then press the remote control button, LED long flashes, indicating learning successfully!

(Learning state can be canceled in light LED1 long lit press S1 button, or wait 30 seconds will automatically exit learn!)

Theoretical distance is about 8-12 meters, but the practical application depends on ambient factors and intermediate barrier (such as a diaphragm, glass or other materials blocked), receiver using HX1838T (T version of very good quality, non-ordinary experiment receiver used), may receive a 38K frequency remote control code for any data!

Note: The vast majority of home appliances remote control can be studied to identify, but air conditioning remote control, non-38KHz remote control can not be learned!
