KL-CW11 adopts a superheterodyne circuit. It has high sensitivity, high reliability, and competitive price. It’s widely used in remote garage door openers, auto gates as retract type, brakes, factory automatic, communication and security system, etc.
433 MHz RF receiver module is the most common and cheapest RF receiver for commercial use. This module helps to receiver the 433MHz frequency commonly but it also has a node on it that is changeable by users for different frequencies. The variable node can adjust the frequency from 315MHz to 433MHz.
