3.1. Wiring Awọn isopọ

The HWT3100-TTL sensor utilizes a TTL serial communication interface. Ensure correct wiring to your microcontroller or data acquisition system:

• VCC (Red Wire): Connect to the positive power supply (typically 3.3V or 5V, depending on your system's TTL logic level).
• RX (Green Wire): Connect to the TX (transmit) pin of your microcontroller/system. This is the sensor's receive data line.
• TX (Yellow Wire): Connect to the RX (receive) pin of your microcontroller/system. This is the sensor's transmit data line.
• GND (Black Wire): Connect to the common ground of your power supply and microcontroller/system.

Pataki: Double-check all connections before applying power to prevent damage to the sensor or connected devices.

3.2. Iṣagbesori

Mount the sensor securely in the desired orientation. For accurate heading measurements, ensure the sensor is placed away from strong magnetic fields (e.g., motors, large metal objects, power cables) that could interfere with geomagnetic readings.

Once wired correctly, apply power to the VCC and GND pins. The sensor will begin its initialization sequence.

4.2. Data Output

The HWT3100-TTL outputs data via its TX pin using serial communication. The default baud rate is 9600 bps. Data includes three-axis magnetic field values (X, Y, Z) and the calculated heading angle.

4.3. Using PC Software (RM3100 Host Computer Software)

For advanced configuration, data visualization, and logging, WitMotion provides dedicated PC software (e.g., RM3100 Host Computer Software). Connect the sensor to your computer via a TTL-to-USB converter (not included) and use the software to:

• View real-time magnetic field data and heading angle.
• Configure sensor parameters such as output rate and baud rate.
• Perform calibration procedures for improved accuracy.

• Ko si Ifihan Data:
  • Verify all wiring connections (VCC, RX, TX, GND) are correct and secure.
  • Ensure the sensor is receiving adequate power.
  • Check that your receiving device (microcontroller/PC) is configured to the correct baud rate (default 9600 bps).
  • Confirm the serial port on your receiving device is open and listening.
• Inaccurate Heading/Magnetic Readings:
  • Relocate the sensor away from potential sources of magnetic interference (e.g., magnets, motors, power lines, large ferrous objects).
  • Ensure the sensor is mounted stably and not subject to vibrations.
  • Perform a calibration using the WitMotion PC software if available, especially after initial installation or relocation.
