4 Channel 315MHz Key Wireless Remote Control

The 4 Channel 315MHz Wirelesss Remote Control Kit is ideal for short-range wireless control application. The super-regenerative receiver module using the LC oscillator circuit containing amplifier shaping design.The output data signal is decoded high signal. It is extremely easy to use and inexpensive. The transmitter part have 4 decoder output.

Receiver module has been tuned to 315MHz and works at 5V DC power. Four buttons in the transmitter corresponds to four data pins in the receiving board (D0 , D1 , D2 , D3). Pressing a button in the remote produces a logic HIGH state in the corresponding data pin in the receiver board.

Features:

• Operating voltage:
  • DC 12V (A23 battery) for remote control
  • DC 5V for decoding receiver board.
• 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
• Receiver sensitivity is -98dB
