OPEN-SMART Long Range 315MHz RF Wireless Transceiver Kit for Arduino
The kit includes one pair of transmitter and receiver modules and one pair of spring antennas for increasing the communication distance. And the frequency is 315MHz. It is very popular for remote control systems£¬ such as wireless doorbell£¬ remote control rolling gates£¬ smart car£¬ smart home£¬ etc. About transmitter module (onboard square module) - Compatible with Arduino - Arduino Library: VirtualWire - Working voltage: 4 - 12VDC - Working current: 40mA - Transmit power: 27dBm@12V (large power) - Working frequency: 315MHz - Transfer rate: 4.8kbps (max) - Transmission distance: When supply poower is 5V£¬ the open area transmission distance can be increased to 150 meters. The supply voltage is larger£¬ the transmission distance farther. - Antenna: Onboard 315MHz dedicated PCB Antenna. About receiver module (rectangle shape): - Compatible with Arduino - Arduino Library: VirtualWire - Operating voltage: 2 - 5.5VDC - Working frequency: 315MHz - Working Current: 2mA - Sensitivity: -110db - Antenna: Onboard 315MHz dedicated PCB Antenna - Great for DIY project.
