Product Name: 10 sets 315Mhz RF transmitter and receiver link kit for Arduino/ARM/MCU WL Receiver module parameters Product Model MX-05V Operating voltage: DC5V quiescent current: 4MA Receiving Frequency: 315MHZ Receiver sensitivity:-105DB Size: 30 * 14 * 7mm external antenna: 32CM single core wire, wound into a spiral Technical parameters of the transmitter head Product Model: MX-FS-03V Launch distance :20-200 meters (different voltage, different results) Operating voltage :3.5-12V Dimensions: 19 * 19mm Operating mode: AM Transfer rate: 4KB / S Transmitting power: 10mW Transmitting frequency: 315M An external antenna: 25cm ordinary multi-core or single-core line Pinout from left ? right: (DATA; VCC; GND) Application environment Remote control switch, receiver module, motorcycles, automobile anti-theft products, home security products, electric doors, shutter doors, windows, remote control socket, remote control LED, remote audio remote control electric doors, garage door remote control, remote control retractable doors, remote volume gate, pan doors, remote control door opener, door closing device control system, remote control curtains, alarm host, alarm, remote control motorcycle remote control electric cars, remote control MP3. Remark VCC voltage module operating voltage and good power filtering; A great influence on the antenna module reception, preferably connected to the 1/4 wavelength of the antenna, generally a 50 ohm single-core wire, the length of the antenna 315M approximately 23cm Antenna position has also affected the reception of the module, the installation, the antenna as possible straight away from the shield, high pressure, and interference source; frequency used to receive, decode and oscillation resistor should match with the transmitter.
