RF 433 MHz Transmitter Receiver Wireless Module
Enable reliable short-range wireless communication in your projects with this RF 433 MHz Transmitter and Receiver Module pair. Operating at the globally popular 433 MHz ISM band, this module set allows you to send and receive data wirelessly over distances up to 200 meters (open air, with antenna). Ideal for remote control systems, home automation, wireless sensor networks, and IoT prototyping, this affordable module pair is a staple for hobbyists, students, and engineers alike. Available now from The Engineer Store, Bengaluru, with fast shipping, expert technical support, and a 7-day warranty on manufacturing defects.
Key Features
- 433 MHz ISM Band Operation: License-free frequency band widely used for short-range wireless communication worldwide.
- Separate Transmitter & Receiver Modules: Dedicated TX and RX boards for flexible integration into any project.
- Long Communication Range: Up to 200 meters in open air (with proper antenna); approximately 20-50 meters indoors depending on obstacles.
- ASK/OOK Modulation: Amplitude Shift Keying modulation for simple, low-power data transmission.
- Wide Operating Voltage: Transmitter operates from 3V to 12V; receiver operates at 5V - compatible with Arduino, ESP, PIC, STM32, and more.
- Low Power Consumption: Minimal current draw makes it suitable for battery-powered and portable applications.
- Easy Microcontroller Integration: Simple DATA pin interface - connect directly to any digital I/O pin on Arduino, Raspberry Pi, or other MCUs.
- Compact Form Factor: Small PCB footprint allows easy embedding into enclosures and custom PCB designs.
- Antenna Support: Solder a 17.3 cm (quarter-wavelength) wire antenna to significantly boost range and signal quality.
- Software Library Support: Fully compatible with popular Arduino libraries such as VirtualWire and RadioHead for quick prototyping.
