433 MHz Wireless Transmitter Receiver Kit for Micro Controller

This kit comes with the MX-FS-03V transmitter module (3.5-12V), and the matching MX-05V receiver module (5V). The typical transmission range is 20-200m, dependingon the power supply, and with a straight quarter wave monopol antenna (l = /4)with173mm length (just a piece of wire).Better antenna designs, like Yagi for example, can be good for a transmission distance up to some km.

There are example sketches for Arduino and the necessary “VirtualWire” library in the download section below.
