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. And the 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 inSpecification:
Transmitter module:
Working voltage: 3V ~ 12V
Working current: 20mA ~ 28mA
Standby current: 0mA
Working frequency: 315MHz
Transmitter distance: >500m (sensitivity can be above -103dBm if in the wide field)
Receiver module:
Working voltage: DC 5V
Working current: 4mA
Modulation mode: OOK (AM)
Working temperature: -10°C ~ +70°C
Receiving sensitivity: -110d
