RF 315MHz module RF Transmitter Receiver Module 315MHz Wireless Link Kit 315MHz Spring Antenna for Arduino

Description Working voltage: 3V ~ 12V Working current: 20mA ~ 28mA Standby current: 0mA Working frequency: 315MHz 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 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 increased to 5 meters. The supply voltage is larger, the transmission distance farther. Specification: 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: -110dB Pin Description: Transmitter module: PIN1 ATAD: data input PIN2 VCC: power PIN3 GND: power - Receiver module: PIN1 ANT: antenna PIN2 VCC: power PIN3/4 DATA: data output PIN5 GND: power - Application: Transmitter module: Wireless calling system, burglar alarm, wireless data transmission, automated data acquisition system Receiver module: Wireless remote control switch, remote control socket, data transmission, remote control toys, Anti-theft alarm host Package Included: 1 x 315MHz RF Wireless Receiver module 1 x 315MHz RF Wireless Transmitter module undefined
