Detailed Product Description:

The 433MHz RF Transmitter and Receiver Module Pair is the go-to solution for anyone looking to add wireless capabilities to their projects without breaking the bank. This low-cost yet highly effective wireless data communication kit is perfect for a vast array of applications, from building simple remote controls and wireless sensor networks to creating sophisticated home automation systems. The modules operate on the globally recognized 433.92MHz frequency band, making them a popular and accessible choice for hobbyists and professionals alike.

The modules employ Amplitude Shift Keying (ASK) modulation, a simple method that makes them easy to interface with microcontrollers like Arduino and Raspberry Pi. The transmitter module typically operates on a wide voltage range (3V to 12V), while the receiver is a 5V module with low power consumption. This design flexibility allows for use in both battery-powered and mains-powered projects. With an effective range of up to 100 meters in open space and data rates up to 10kbps, they are more than capable of handling simple data transmission for projects such as wireless doorbells, garage door openers, and remote-controlled lighting.

Getting started is simple, with just a few pins to connect: VCC, GND, and DATA. The performance can be significantly enhanced by adding a simple 17cm wire antenna to the modules. Whether you are a student working on a school project or an engineer prototyping a new IoT device, the 433MHz RF transceiver module offers a reliable, low-cost, and easy-to-implement wireless link, proving that you don't need complex, expensive hardware to create powerful wireless applications.

This 433 MHz RF Transmitter and Receiver Module Pair enables low-cost, short-range wireless communication between microcontrollers. Commonly used in home automation, remote controls, wireless data logging, and IoT applications, these modules operate using ASK modulation and can transmit serial data over RF without wires.

The transmitter module sends digital signals wirelessly via its antenna pin, while the receiver module detects and outputs the transmitted data. Paired with a simple encoder/decoder (like HT12E/HT12D) or software serial, it allows basic one-way wireless communication between devices.
