R44.80
Use these two compatible RF receiver and transmitter modules to send AM Radio Waves directly between two Ardruinos.
This package includes both the RF receiver and the transmitter modules.
Transmitter : Working voltage: 3V - 12V fo max. power use 12VWorking current: max Less than 40mA max , and min 9mAResonance mode: (SAW)Modulation mode: ASKWorking frequency: Eve 315MHz Or 433MHz Transmission power: 25mW (315MHz at 12V)Frequency error: +150kHz (max)Velocity : less than 10KbpsSo this module will transmit up to 90m in open area .Receiver :Working voltage: 5.0VDC +0.5VWorking current:≤5.5mA maxWorking method: OOK/ASKWorking frequency: 315MHz-433.92MHzBandwidth: 2MHzSensitivity: 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.
the connection for this module is very easy .for Transmitter :Vcc ->5VATAD ->D12" (This pin number can be changed in code)Gnd >>> GndReceiver :Vcc -> 5VData -> D12Gnd -> Gnd
There is a popular Library for arduino Called "" VirtualWire"" Created by Mike McCauley that does all the hard work for you, available HERE
An instructable guide is available HERE
Remember to add an external antenna for maximum range!Can be used with or without an Arduino!
