Module used:
1. The power LED indicator lights up correctly, 5 seconds after the module works properly, the relay is working!
2. Press each S1 button once, the relay switches work simultaneously, turn on or off, light up or go out simultaneously!
3. After each infrared remote learning success, press the remote learning success button (remote learning method below), the relay working state will be displayed in time, on or off, light up or off at the same time!
There are two types of remote learning implementation methods:
1. Press and hold the S1 button for more than 5 seconds, the LED1 light is on, indicating that it has entered the learning state, then release the S1 button, and then press the remote control button, the indicator light is on, as long as the tightness is lit, it indicates that the learning is successful!
2. Positioning with the infrared receiver head remote control module, press any button for 10 seconds, the LED1 light is in the learning state, then press the remote control button, the indicator light is on as long as the scintillation says learning is successful!
(Cancel the learning state, you can click the S1 button when LED1 is long bright or wait for 30 seconds, it will automatically exit the learning state!)
The theoretical distance is 8 to 12 meters, but in actual use, depending on the surrounding environment and the intermediate blocking factors (such as diaphragm, glass or other materials blocking), the receiver head uses HX1838T (the very good quality T version generally does not receive the head). The experimental use can receive any 38K code frequency remote control data!
Note: Most of the home appliance remote controls can be learned to identify, but the 38KHz air conditioner remote control is a remote control that cannot be learned!
