DC 5V 1-Channel IR Relay Module 2 Key Remote Control Switch Infrared

Description:
The learning infrared remote control switch, as the name suggests, allows the single-chip microcomputer to memorize the key value data of a key of the remote control, and let it control the relay switch. By re-learning, the stored key data can be modified. For example, you use the remote control this time. If you want to use the "8" key for learning, you can use "8" as the control button after success, and the data will not be lost when the power is turned off. If you want to use the "9" button as the control, you need to relearn the microcontroller and make changes.

Module Instructions:
1. Power on, the wiring is correct, the LED indicator is on, the module will work normally after 5 seconds, and the relay will work at the same time!
2. Long press the S1 button, the indicator light flashes, the module enters the learning mode, press any button on the remote control, the indicator light stops flashing, and the learning is completed
3. The working mode of the relay (self-locking or jog) can be switched through the jumper cap
4. The remote control has a built-in battery

Note:

1. The power supply must be 5V, the voltage higher than 5.5V will burn the microcontroller
2. The remote control of most home appliances can be learned and recognized, but the remote control of the air conditioner, non-38KHz remote control cannot be learned!

3. The theoretical distance is about 8-12 meters, but the actual application depends on the surrounding environmental factors and intermediate barriers (such as diaphragm, glass or other materials). The receiving head adopts HX1838T (very good quality T version, not a general experience) Receiving head used), can receive all remote control code data at a frequency of 38K!
