Receiver Module Parameters:  <br />● Operating voltage: DC 5V <br />● Quiescent current: 4MA <br />● Receiving frequency: 433.92MHZ <br />● Receiver sensitivity: -105DB <br />● External antenna: 32cm single core wire， wound into a spiral <br /><br /> Transmitter Module Parameters:    <br />● Launch distance: 20 - 200 meters (different voltage， different results) <br />● Operating voltage: 3.5 - 12V  <br />● Operating mode: AM <br />● Transfer rate: 4KB / S <br />● Transmitting power: 10mW <br />● Transmitting frequency: 433M <br />● An external antenna: 25cm ordinary multi-core or single-core line <br />● Pinout from left → right: (DATA; VCC; GND) <br /><br /> Application:   <br />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. <br /><br /> Remarks:    <br />1. VCC voltage module operating voltage and good power filtering; <br />2. Great influence on the antenna module reception， preferably connected to the 1/4 wavelength of the antenna， typically 50ohm single conductor， the length of the antenna 433MHz of about 17cm; <br />3. 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.<br /><br /><br />  for complete imformation<br /><br />    Specifications<br />General<br />	 Type: Wireless transmission module                                                  <br />                        Material: FR4 board                                                  <br />                        Compatibility: Ardunio                                                	<br />Weight and Size<br />	 Product Weight: 2 g (Transmitter Module )  2 g (Receiver Module )                                                  <br />                        Product Size(L x W x H): 3.0 x 1.4 x 0.7 cm / 1.2 x 0.6 x 0.3 inches (Receiver Module)  1.9 x 1.9 x 0.7 cm / 0.7 x 0.7 x 0.3 inches (Receiver Module )                                                	<br />Package Contents<br />	 Package Contents: 1 x Transmitter Module， 1 x Receiver Module                                                	<br /><br /><br /><br />                                                <br />
