IR 1 Channel Infrared Receiver Driving Switch Relay Driver Module Board 5V + Active Remote Controller
Learning infrared remote control switch, as the name implies, can let the single chip microcomputer to remember a button on the remote control key data, and let it control relay switch, through the study of again, can modify the keys of the stored data, for example, the use the "8" button on the remote control to you to learn, can use the "8" to do after successful control keys, data is not lost when power supply drop, if you want to use button "9" as a control, it needs to make changes to a microcontroller learning is, don't understand please look at the video above results!
Module USES:
1. Electric power, wiring correct LED indicator, 5 seconds after the module to work properly, relay and work!
2. Each press S1 button once, relay switch working state at a time, on or off, lights light up or put out at the same time!
3. After the success of the infrared remote learning, each press the remote learning success (remote learning methods below), relay switch working state at a time, on or off, lights light up or put out at the same time!
Remote learning operation method has two kinds:
1. Hold the S1 button more than 5 seconds, light LED1 lights, said into the learning state, then loosen the button S1, then press the remote control button, indicator light as long as scintillation, says study has successfully!
2. Alignment with the remote control module of infrared receiving head, long press any key to 10 seconds, light LED1 lights, said into the learning state, then press the remote control button, indicator light as long as scintillation, says study has successfully!
(cancel the learning status can click the S1 button when LED1 long bright, or wait 30 seconds will automatically quit learning!)
Theory of distance is 8 to 12 meters, but depends on the surrounding environment factors in actual applications and intermediate blocking (such as the diaphragm. Glass or other materials blocking), receiving head adopts HX1838T (T version of the quality is very good, not generally receive head) used in the experiment, can receive 38 k any remote control frequency coded data!
Note: most of the remote control of home appliance can be learn to identify, but air conditioning remote control, the 38 KHZ is remote control can't be learned!
