KL-CW11 utilizes a superheterodyne circuit, offering high sensitivity, reliability, and competitive pricing. It finds widespread application in remote garage door openers, retractable auto gates, brakes, factory automation, communication systems, and security setups.
The 433 MHz RF receiver module is a common and cost-effective choice for commercial use. While it primarily operates at 433 MHz, users can adjust a variable node to accommodate different frequencies ranging from 315 MHz to 433 MHz.
Although the module can receive data, it cannot decode or display it directly without an intermediary device. Typically, smart boards or microcontrollers interface with the receiver. The module’s output arrives in an encoded format that requires programming and encoders for decoding. Additionally, it pairs well with the 433 MHz RF transmitter module.
Applications:
- Home automation
- Transmit Serial data for a short distance.
- Car security system
- Wireless logging
- Short distance communication
Features:
- The Transmitter offers one-way communication through 433.92MHz frequency at a 1Kb data rate
- It operates at 3-12V which is the power operating volts of most of the microcontrollers and boards.
- The module uses the ASK modulation method to transmits the data.
- It is one of the low-cost power effective modules for both commercial and developers.
- 433MHz Transmitter is one of the oldest RF transmitters and it has a lot of applications and examples on the internet which helps to achieve interfacing with almost every application.
