Description

The Generic MX-05V & MX-FS-03V RF Transmitter Receiver Module Kit implements a straightforward Amplitude Modulation (AM) wireless communication link on the 315MHz frequency band. This pair is engineered for cost-effective, low-data-rate remote control applications, where bi-directional communication is not required. The transmitter module’s wide operating voltage allows for flexibility in power sourcing, from a 3.3V logic-level supply up to 12V for increased range.

The receiver module’s high sensitivity of -105dB ensures reliable decoding of the transmitted signal, maximizing the effective range in open environments. Both modules feature a minimal three-pin interface, making them plug-and-play compatible with common development platforms like Arduino for controlling relays, sensors, or motors wirelessly. The included 25cm wire antenna provides a basic radiating element, with performance scaling based on antenna length and orientation.

Key Features

  • Low-cost wireless solution for one-way remote control and simple telemetry systems.
  • Long-range capability up to 200 meters line-of-sight under ideal conditions with the provided wire antenna.
  • High-receiver sensitivity (-105dB) ensures robust operation in the presence of signal attenuation and interference.
  • Wide transmitter voltage range (3.5V-12V) enables use with various power sources, including batteries and regulated supplies.
  • Compact PCB footprints (30x13mm TX, 19x19mm RX) allow for easy embedding into finished projects and enclosures.
  • Simple integration via standard DATA, VCC, and GND pins, compatible with most microcontroller GPIO.
  • Operates on the globally accessible 315MHz ISM band, suitable for regional remote control applications.

Applications

  • Wireless remote controls for garage doors, gates, and lighting systems.
  • Simple security and alarm system triggers (door/window sensors).
  • Toy and model vehicle wireless control interfaces.
  • Basic home automation for non-critical switch and relay control.
  • DIY telemetry for transmitting sensor data (temperature, status) over short distances.

Frequently Asked Questions

How do I connect these 315MHz RF modules to an Arduino Uno?

Connect the transmitter's VCC pin to a 3.5V-12V source, GND to ground, and DATA to a digital pin. For the receiver, connect VCC to 5V, GND to ground, and DATA to another digital pin configured as an input. Use the VirtualWire or RCSwitch library to handle the AM signal encoding and decoding. Ensure both modules share a common ground for reliable operation.

What is the effective range, and how can I increase it?

The specified 200-meter range is under ideal line-of-sight conditions. To increase range, ensure a clear path, orient the 25cm wire antennas vertically, and consider using a higher voltage (up to 12V) on the transmitter. For the receiver, using a stable, low-noise 5V power supply and keeping wiring short can improve sensitivity and reduce interference, thereby extending practical range.

Can I use these modules to transmit sensor data from one Arduino to another?

Yes, you can transmit simple sensor data. The 4KB/s data rate is suitable for sending periodic readings like temperature or switch states. You must write firmware to convert the sensor reading into a serialized code, transmit it via the TX module, and decode it on the receiving Arduino using the same protocol library. Ensure your data packet size is small to avoid exceeding the limited bandwidth.
