Wireless Control LED using radio Frequency

Transmitter : 

Working voltage: 3V – 12V  fo max. power use 12V
Working current: max  Less than 40mA max , and min 9mA
Resonance mode: (SAW)
Modulation mode: ASK
Working frequency: Eve 315MHz  Or  433MHz 
Transmission power: 25mW (315MHz at 12V)
Frequency error: +150kHz (max)
Velocity :  less than 10Kbps

So this module will transmit up to 90m in open area .

Receiver :

Working voltage: 5.0VDC +0.5V
Working current:≤5.5mA max
Working method: OOK/ASK
Working frequency: 315MHz-433.92MHz
Bandwidth: 2MHz
Sensitivity: excel –100dBm (50Ω)
Transmitting velocity: <9.6Kbps (at 315MHz and -95dBm)

 the use of an optional antenna will increase the effectiveness of your wireless communication. A simple wire will do the trick.
