Arduino 12v 433mhz 12 Channel Wireless Controlled RF Receiver Relay Module (boxed)

Features: wireless control, easy to install control lights, motors, fans, electrically operated doors/locks/windows/shutters/cars or other devices with dc 12 v. You can turn on/off the receiver from anywhere within a reliable distance with the transmitter (remote control), the wireless rf signal can pass through walls, floors and doors. This switch can learn different coding remote controllers (2262,1527,etc) One/several transmitters can control one/several receivers at the same time. If you use two or more receivers in the same place, you can set them with different codes. If you use multi-button transmitter, you can control the controller with different buttons, it will not affect each other. Transmitting frequency: 433 mhz wireless receiver controller, high confidentiality, stable performance, feature of low power consumption, dial jump line or code key coding. About the receiver:channel: 12 chradio frequency: 433 mhzworking voltage: dc12voutput way: a. 1x2 instantaneous ----- Set jumper on “a & l” b. 1 v v permanent ----- Set 1 pin jumper (don't use jumper)c. 1-12ch toggle--set jumper on “b & l”press momentary transmitter button 1, the receiver relay 1th open, on button 1

the receiver relay 1th close, the same with 2/3/4/5/6/7/8/9/10/11/12. The 12ch are independent. Toggle 1 press the transmitter button 1, the receiver relay 1th open, press the button again 1, the receiver relay 1th closed, the same 2/3/4/5/6/7/8/9/10/11/12. The 12ch are independent. Press the transmitter button permanent 1, the receiver relay 1th open, the relay 2/3/4/5/6/7/8/9/10/11/12 close. Press the transmitter button 2, the receiver relay 2th on, the relay 1/3/4/5/6/7/8/9/10/11/12 off. Press the transmitter button 3, the receiver relay 3rd is open, the relay 1/2/4/5/6/7/8/9/10/11/12 is closed. press the transmitter button 4, the receiver relay 4th is open, the relay 1/2/3/5/6/7/8/9/10/11/12 is closed. ……………. It means the same time. Only 1ch can continue to be permanent. And usually 1ch will be on. Learning way and steps: learning code:input dc12v for receiver, press the learning button on the receiver, led indicator on, release, then push transmitter button, receiver led indicator flash 3 times, it means learning successfully. (cut off the power and connect it again for normal use)trade code: dc12v input for receiver, press the learning button on the receiver and keep it pressed for about 8 s until the receiver led indicator turns off, it means the code has been cleared. About the transmitter: buttons: 12 buttons battery: 23a 12 v (battery not included) frequency: 433 mhz remote control distance: 50-200 m encode: fixed code with solder and learning code
