Features1. The module adopts genuine high quality 10A relay, the maximum load of the interface: 250V/10A AC, 30V/10A DC
2. The jumper cap can switch the working mode of the relay
3. Learning infrared remote control switch, which allows the MCU to remember a key value data of the remote control, so that it can control the switch of the relay
4. Fixed bolt holes for easy installation
5. Theoretical distance up to about 8-12 meters, easy to use
Learning infrared remote control switch, as the name suggests, allows the microcontroller to remember a key value data of the remote control, so that it can control the switch of the relay, by learning again, you can modify the stored key data, for example, you use the "8" key on the remote control to learn, you can use "8" to do the control key after the success, power down data will not be lost, if you want to use the key "9" for control, you need to let the microcontroller learn again will make changes.
Instructions for using the module.
1, power on the power supply, wired correctly LED indicator light, 5 seconds after the module works normally, relays work at the same time!
2, long press S1 key, the indicator light flashes, the module into learning mode, press any key of the remote control indicator light stops flashing learning is complete!
3、Through the jumper cap you can switch the working mode of the relay (self-locking or pointing)
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 obstructions (such as diaphragm, glass or other material obstruction), the receiver head uses HX1838T (very good quality T version, not the general experimental receiver head), can receive 38K frequency data of any remote control code!
Note: Most of the remote controls for home appliances can be learned and identified, but for air conditioners, non-38KHz remote controls cannot be learned!
