Wiring Principle

This module utilizes a serial port connection. When connecting to a USB to TTL converter or a microcontroller, ensure that the 送信 (Transmit Data) pin of the host device (e.g., USB to TTL converter, Arduino) is connected to the RXD (Receive Data) pin of the infrared module. Conversely, the RXD pin of the host device should connect to the 送信 pin of the infrared module. The グランド (Ground) and VCCC の (5V) pins should be connected to the corresponding power supply pins.

• VCCC の: Connect to 5V power supply.
• グランド: Connect to Ground.
• 送信 (Module): Connect to RXD (Host device).
• RXD (Module): Connect to TXD (Host device).

Important: Do not connect TXD to TXD or RXD to RXD. Always cross-connect these pins.

操作手順

The module communicates using serial commands to decode and transmit infrared signals. This allows for control of infrared household appliances or other devices via a computer serial assistant or supporting software.

Serial Communication Exampレ

Commands are typically sent as a sequence of hexadecimal values. Below are examples of common operations:

• Transmit NEC signal (e.g., code 1C 2F 33, data bit 3):

  {A1,F1,1C,2F,33}

• Modify the serial communication address to 0xA5:

  {A1,F2,A5,00,00}

• Modify the baud rate to 4800bps (corresponding to serial number 1):

  {A1,F3,01,00,00}

Refer to the module's specific programming guide or library documentation for a complete list of commands and their syntax.

メンテナンス

This infrared module is a low-maintenance electronic component. To ensure its longevity and reliable operation:

• モジュールを清潔に保ち、ほこりやごみが付かないようにしてください。
• モジュールを極端な温度や湿度にさらさないでください。
• Handle the module with care to prevent physical damage to components or solder joints.
• Ensure stable 5V power supply to prevent damage from voltage変動。

トラブルシューティング

• モジュールが応答しません:
  • Verify all wiring connections, especially TXD/RXD cross-connections and power (5V, GND).
  • Ensure the 5V power supply is stable and correctly connected.
  • Check the serial port settings (baud rate, data bits, parity, stop bits) on your host device to match the module's configuration.
• Infrared transmission/reception issues:
  • Ensure there are no obstructions between the module's IR emitter/receiver and the target device.
  • Check the firing distance; the module is rated for 6-10 meters. Performance may vary with environmental conditions.
  • If decoding, ensure the remote control is transmitting a compatible IR protocol (e.g., NEC). Some complex or brand-specific protocols may require advanced decoding.
  • If different remote buttons return the same code, the module might be performing onboard processing rather than providing raw IR data. Consult specific library or module documentation for raw IR capture capabilities.
• 予期しない動作:
  • Review your code or serial commands for any errors.
  • Ensure the module's firmware is up to date, if applicable.
