RF 433MHz for Transmitter Receiver Module RF Wireless Link Kit +2PCS Spring A... (FREQUENCY: 315MHZ)

SELECTED OPTION:
FREQUENCY: 315MHZ

Features: ? 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 the wireless doorbell, remote control rolling gates, smart car, smart home, etc. ? About transmitter module: ? - Compatible with Arduino - Library: VirtualWire - Working voltage: 3-12VDC - Working current: 3.5mA - Working frequency: 433MHz - Transfer rate: 4.8kbps (max) - Transmission distance: When the spring antennas are soldered to the transmitter and receiver module and the power supply is 5V, the open area transmission distance can be increased to 40 meters. The supply voltage is larger, the transmission distance farther. - Antenna: You can use the wire whose length is 17cm or the spring antenna for 433MHz RF. ? About receiver module (rectangle shape): ? - Compatible with Arduino - Library: VirtualWire - Operating voltage: 4.5 ~ 5.5VDC - Working frequency: 433MHz - Working Current: 1mA - Sensitivity: -105db - Antenna: You can use the wire whose length is 17cm or the spring antenna for 433MHz RF. - Great for DIY project.
