Highlights
- The kit includes one pair of transmitter and receiver modules. 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.
- Transmission distance: When the spring antennas are soldered to 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 315MHz RF.
