433MHz Wireless Transmitter and Receiver RF Module

433MHz Wireless Transmitter and Receiver RF Module

Arduino Connection Kit

The kit includes a pair of transmitter and receiver modules and a pair of antennas to increase the communication distance. It is very popular for remote control systems, such as remote control of gates, smart cars, smart homes, etc.

About transmitter module (square shape):

-Compatible with Arduino;

-Arduino library: VirtualWire;

-Working voltage: 3.5 ~ 12V DC;

-Working frequency: 433MHz;

-Transfer rate: 4KB/S (max);

-Range: 3m (max) 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 is farther.

About receiver module (rectangular shape):

-Compatible with Arduino;

-Arduino library: VirtualWire;

-Working voltage: 4.75 ~ 5.25v DC;

-Working frequency: 433MHz;

-Quiescent current: 4mA;

-Great for DIY project.
