RF Transmitter & Receiver Module – 433MHz Wireless Communication

An RF Transmitter and Receiver system is used to wirelessly send and receive data using radio frequency (RF) signals. These modules are commonly used in wireless communication, remote control systems, robotics, IoT, and security applications.

 RF Transmitter & Receiver Modules

1. RF Transmitter Module (e.g., 433 MHz)

• Power Supply: 3V to 12V (commonly 5V)

• Range: 50 – 100 meters (line of sight)

• Modulation Type: Amplitude Shift Keying (ASK)

• Data Rate: Up to 10 kbps

• Pinout:

  • VCC – Power supply

  • GND – Ground

  • DATA – Sends data (connected to Arduino or microcontroller)

2. RF Receiver Module (e.g., 433 MHz)

• Power Supply: 5V

• Sensitivity: –105 dBm

• Pinout:

  • VCC – Power supply

  • GND – Ground

  • DATA – Two data output pins (either can be used)
