1 Channel 5V Infrared Remote Control Relay Module Infrared Receiver Driving Switch Relay Driver Module Board

The learning infrared remote control switch, as the name implies, allows the single-chip microcomputer to remember the key value data of a key of the remote control, and let it control the switch of the relay. By learning again, 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 power is off. If you want to use the button “9” as control, you need to re-learn 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 learning is complete
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:
The power supply must be 5V, voltage higher than 5.5V will burn the microcontroller

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 experiment) Used receiving head), can receive any remote control code data at 38K frequency!

Note: The remote control of most home appliances can be learned and recognized, but the remote control of air conditioner, non-38KHz remote control can not be learned!

Package includes:
1* Relay module
1* Remote control
