Remote control and instruction manual with decoding receiver board
1) remote control
Working voltage: DC12V (12V 27A battery),
Operating Current: 10mA @ 12V
Radiated power: 10mw @ 12V
Modulation: ASK (Amplitude Modulation)
Transmission frequency: 315 or 433.92MHZ (SAW frequency stabilization)
Transmission distance: 50-100M (Kongkuo, the receiver sensitivity is negative 100dbm)
Encoder Type: Fixed code
2) decoding receiver board
Working voltage DC5V, receiver sensitivity -98db. There are seven pins, respectively, VT, D3, D2, D1, D0, + 5V, GND.
VT is a valid signal high output pin, upon receiving a valid signal, the output pin high, can also drive a relay.
Size: 6.6 * 22 * 41mm
If you want control the higher voltage and current, you can add the relay and get you want.
There are four buttons on the remote controller, respectively corresponding to the received data bits board output pin D0, D1, D2, D3. Press the button to transmit signals, the corresponding data bit will output high.
