Remote control:
Operating voltage: DC 12V(27A / 12V battery x 1)
Operating current: 10mA at 12V
Radiated power: 10mW at 12V
Transmission distance: 50m – 100m (open field, the receiver sensitivity of -100dbm)
Transmitting frequency: 315MHZ
Modulation mode: ASK (Amplitude Modulation)
Encoder types: fixed code
Decoding receiver board:
Operating voltage: DC 5V
Receiver sensitivity is -98dB
Leg 7 bits: VT, D3, D2, D1, D0, +5V and GND
VT is a valid signal high output pin upon receiving a valid signal, the pin output high, may also drive the relay
Size: 6.6 x 22 x 41mm
Pin Name Function Description and Usage
1) VT output status indication
2) D3 data output
3) D2 data output
4) D1 data output
5) D0 data output
6) 5V power supply positive
7) GND power supply negative
8) ANT connect the antenna terminal
Total of eight external receiver module interface. “5V” means positive power supply, “D0, D1, D2, D3” represents the output, “GND” means power supply is negative, “ANT” means connected the antenna terminal.
Far as the pro-distance requirements, then the best quarter-wavelength antenna, generally use 50 ohm single wire, the length of the antenna 315M is about 23cm, 433M is about 17cm.
