OPEN-SMART 433MHz RF Wireless Receiver Module Transmitter kit + 2PCS RF Spring Antenna

Description: 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 433MHz. It is very popular for remote control systems, such as Remote control rolling gates, smart cars, smart home, etc. About the transmitter module (square shape): - Compatible with Arduino; - Library: VirtualWire; - Operating voltage: 3.5~12V DC; - Working frequency: 433MHz; - Transfer rate: 4KB/S (max); - Transmission distance: 3 m (maximum) at VCC = 5V without additional antenna. When the spring antennas are soldered to the 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; - Library: VirtualWire; - Operating voltage: 4.75~5.25V DC; - Working frequency: 433MHz; - Quiescent Current: 4mA; - Great for DIY project.

Package includes: 1 x 433MHz RF transmitter module 1 x 433MHz RF receiver module 2 x 433MHz spring antenna (2.7cm)
