WayinTop 3 Set 433MHz RF Wireless Transmitter and Receiver Module + RF 433MHz Copper Spring Antenna Kit, High Frequency Super Regenerative Transceiver Module for Burglar Alarm

• 【How to Use】The VCC voltage must be consistent with the module's working voltage and must stay in good power filtering.
• 【Perfect Kit】This kit includes 3 pairs of transmitter and receiver modules and 3 pairs of spring antennas for increasing the communication distance. And the frequency is 433MHz. It is very popular for remote control systems, such as Remote control rolling gates, smart car, smart home, etc.
• 【Easy to Use】Great influence on the antenna module reception, preferably connected to the 1/4 wavelength of the antenna, typically 50 ohm single conductor. The length of the antenna 433M is about 17cm.
• 【Wireless Transmitter Modules】allow your to wirelessly comunicate with others, or with radio frequency (RF) controlled devices that operate in the same frequency (433Mhz in this case).
• 【Warm Tips】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.

WayinTop: Your Top Way to Inspiration. Specification: The Transmitter Module (Square Shape): Operating Voltage: 3.5-12VDC Size: 19mm x 18.9mm AM transfer rate: 4KB / S Transmitting Power: 10mW Amplitude Modulation: ASK or OOK Transfer Rate: <10Kbps Working method: AM Transmission frequency: 433.92MHZ External antenna: 25cm single core wire, coiled into a spiral Pinout from left to right: (DATA; VCC; GND) - Launch Distance: 20-200 Metres - Please Notice: The distance will be influenced by its working voltage, rainy or thunderstorm day, signal shielding device, signal interference source, high-tension power wire. Better to keep the modules from them.
