ALAMSCN 6 Set 433MHz RF Wireless Transmitter and Receiver Module Compatible with Arduino by Amazon.co.uk

• This kit includes 6 pairs of transmitter and receiver modules for increasing the communication distance. And the frequency is 433MHz.

• 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.

• Allow your to wirelessly comunicate with other, or with radio frequency (RF) controlled devices that operate in the same frequency (433Mhz in this case).

• Note: 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.

• Widely use for receiver module, remote control rolling gates, remote control MP3, remote control LED, remote control audio, smart car, smart home, etc.
