315MHZ Wireless Remote Control Receiver module

Descriptions

• 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
  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
  
  
• Improve signal distance
  To improve the distance, an external antenna is required.
  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.
