1-Circuit 5V Infrared Remote Control Relay Module

Product Information:

Learning infrared remote control switch, as the name suggests, allows the microcontroller to remember a key value data of the remote control and let it control the switch of the relay. By learning again, you can modify the stored key data. For example, if you use the "8" key on the remote control this time to learn, you can use the "8" key to control the key without losing power down data. If you want to use the "9" key as the control, You need to re learn the microcontroller and make changes

Module Instructions:

1. When the power is turned on and the wiring is correct, the LED indicator lights up. After 5 seconds, the module operates normally and the relay operates simultaneously!

2. Long press the S1 key, the indicator light flashes, and the module enters the learning mode. Press any key on the remote control to stop flashing, and the learning is complete

3. The relay operation mode can be switched (self-locking or inching) through the jumper cap

Be Careful:

The power supply must be 5V. If the voltage is higher than 5.5V, the microcontroller will be burned, and this store is not responsible

The theoretical distance is about 8-12 meters, but in practical applications, it depends on the surrounding environmental factors and intermediate barriers (such as membranes, glass, or other materials). The receiver head uses HX1838T (a high-quality T-version receiver that is not commonly used in experiments), and can receive any remotely encoded data at a 38K frequency!

Most home appliance remote controls can be learned to recognize, but air conditioning remote controls, non 38KHz remote controls, cannot be learned!
