Long Range 315MHz RF Wireless Transceiver Kit
If you've been finding success with inexpensive RF data modules, however need more range - then these long-range 315MHz RF wireless modules from PMD Way are for you.
They work in the same wasy as the cheaper modules, however have a greater power output and a solid, convenient PCB antenna to keep things neat.
Connections are simple: power (+ and -/GND) and data in for the transmitter, or data out for the receiver. Pin spacing is 2.54mm.
You can use the VirtualWire library for Arduino. Each pack includes one receiver and one transmitter.
- Transmitter working voltage: 4~12VDC
- Transmitter working current: 40mA
- Quiescent current: ~4mA
- Transmit power: 27dBm @ 12VDC
- Working frequency: 315MHz
- Transfer rate: 4.8kbps (max)
- Transmission distance: When supply poower is 5V, the open area transmission distance is around 150 meters. To increase transmit range, you can increase the power to the transmitted up to 12V DC.
- Antenna: Onboard 315MHz dedicated PCB Antenna.
- Receiver operating voltage: 2~5.5V DC
- Receiver current: 2mA
- Sensitivity: -110db
- PCBs measure ~30 x 24mm
