433Mhz Wireless RF Transmitter Receiver Board With HT12D HT12E

The 433MHz Wireless RF Transmitter and Receiver Board is an efficient and cost-effective solution for wireless communication in remote control applications, IoT projects, and home automation systems. It utilizes ASK (Amplitude Shift Keying) modulation for stable data transmission and reception over distances of up to 100-500 meters (depending on obstacles and antenna quality).

Key Features:

✅ 433MHz Frequency – Ideal for remote control and wireless data transmission.
✅ HT12E Encoder & HT12D Decoder – Ensures secure data encoding and decoding.
✅ Low Power Consumption – Efficient power usage for battery-operated applications.
✅ Simple Communication Protocol – Easy to integrate with microcontrollers like Arduino and PIC.
✅ Adjustable Antenna Support – Improves signal strength for longer-range applications.

Working Principle:

• HT12E (Encoder) converts parallel input data into serial form for transmission.

• 433MHz RF Transmitter Module sends encoded data wirelessly.

• 433MHz RF Receiver Module receives the signal and passes it to HT12D (Decoder), which converts it back to parallel data.

Applications:

🔹 Remote Control Systems – Wireless control of lights, fans, and appliances.
🔹 Home Automation – Integrates with smart home devices for remote operation.
🔹 Security Systems – Used in wireless alarm and access control systems.
🔹 Wireless Data Transmission – Communicates between microcontrollers over short distances.

Package Includes:

• 1 x 433MHz RF Transmitter Module

• 1 x 433MHz RF Receiver Module

• 1 x HT12E Encoder IC

• 1 x HT12D Decoder IC

This 433MHz RF module with HT12D/HT12E is perfect for beginners and professionals looking to build wireless communication systems efficiently.
