Wireless Transmitter Modules: It allow your to wirelessly communicate with radio frequency (RF) controlled devices that operate in the same frequency (433Mhz in this case). Easy to Use: The antenna has a great influence on the receiving effect of the module,it is better to connect the antenna with 1/4 wavelength. Generally, 50 ohm single-core conductor is used. The antenna length of 433M is about 17cm.(Note:No antenna, please bring your own antenna.) Nice range (using antenna on both), you can send strings (text) from one point to another. If you want to automate your house without pulling cables then this device will help you well. Note: The VCC voltage should be consistent with the working voltage of the module, and the power filter should be done well; The position of the antenna should be as straight as possible, away from the shield, high voltage and interference source.When used,the receiving frequency, decoding mode and oscillating resistance should match the transmitting. Applications: The transmitter and receiver modules for increasing the communication distance. And the frequency is 433MHz.It is widely used in remote control systems, such as remote control switch/curtain/sockets/LED/audio/door/rolling gate/door opener, shutter and other door control systems, alarm host, alarm, remote control motorcycle, remote control controlled electric vehicle, remote control MP3, receiving module, automobile anti-theft products, home anti-theft products, electric doors,etc. Package included: 5 x 433MHz Wireless Transmitter Module+5 x 433MHz Wireless Receiver Module

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.
Applications:
- These modules are used for projects when you need to communicate wirelessly between 2 devices.
It is possible to increase the range by adding a small length of cable which the device will use as an aerial.
- It is very popular for remote control systems, such as Remote control rolling gates, smart car, smart home, etc.
Package Included：
5*433MHz RF Wireless Transmitter and Receiver Module
