RF Transmitter Receiver Module 315MHz Wireless Link 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 Remote control rolling gates£¬ smart car£¬ smart home£¬ etc. About the transmitter module (square shape): - Compatible with Arduino; - Arduino Library: VirtualWire; - Operating voltage: 3.5~12V DC; - Working frequency: 315MHz; - Transfer rate: 4KB/S (max); - Transmission distance: 3m (maximum) at VCC = 5V without additional antenna. When the spring antennas are soldered to transmitter and receiver module£¬ the transmission distance can be increased to 5 meters. The supply voltage is larger£¬ the transmission distance farther. About receiver module (rectangle shape): - Compatible with Arduino; - Arduino Library: VirtualWire; - Operating voltage: 4.75~5.25V DC; - Working frequency: 315MHz; - Quiescent Current: 4mA; - Great for DIY project.
