3.2. Bluetooth Connection Steps

Follow these steps to connect your BWT901CL sensor via Bluetooth:

1. మీ స్మార్ట్‌ఫోన్ లేదా PCలో బ్లూటూత్ ప్రారంభించబడిందని నిర్ధారించుకోండి.
2. Open the WITMOTION application.
3. Turn on the sensor. For WT9011DCL, press and hold the button for 3 seconds until the green light flashes. For BWT901CL and BWT61CL, simply power them on.
4. In the app, navigate to the "Device Scan" or "Scan" section.
5. Select the corresponding device from the list. WT901BLECL will appear as "WT901BLE", and BWT901CL will appear as "HC-06".
6. Once connected, the app will display real-time sensor data.

4.1. Data Output and Interface

The WITMOTION app provides various data outputs and interfaces for monitoring the sensor's performance:

• త్వరణం: Displays 3-axis acceleration data.
• గైరోస్కోప్: Shows 3-axis angular velocity.
• కోణం: Provides pitch, roll, and yaw angles.
• అయస్కాంతం: Displays 3-axis magnetic field data.
• Quaternion: Shows quaternion values for orientation.

You can observe real-time data curves and numerical values for each parameter. The app also features a dashboard for an intuitive overview of all sensor attitude motion.

4.2. క్రమాంకనం

Calibration is crucial for accurate sensor readings. The app provides options for:

• Acceleration Calibration: Place the sensor on a horizontal surface and initiate calibration. The X and Y acceleration values should return to 0, and Z-axis should show 1G, indicating successful calibration for acceleration bias.
• Magnetic Calibration: This requires careful execution to avoid magnetic interference. Ensure the sensor is away from mobile phones, computers, or metal surfaces. The calibration process involves rotating the sensor 360 degrees horizontally and vertically. The app will guide you through the steps.

4.3. కాన్ఫిగరేషన్ సెట్టింగులు

Adjust various parameters to optimize sensor performance for your specific application:

• అవుట్పుట్ రేటు: Change the data output frequency. The default is 10Hz, but it can be set up to a maximum of 200Hz.
• ఫ్యాక్టరీ పునరుద్ధరణ: అన్ని సెట్టింగ్‌లను వాటి డిఫాల్ట్ విలువలకు రీసెట్ చేస్తుంది.
• Rename Function: Allows you to customize the device name (e.g., "WT123").

5. నిర్వహణ

To ensure the longevity and optimal performance of your BWT901CL sensor, follow these general maintenance guidelines:

• పరికరాన్ని శుభ్రంగా మరియు దుమ్ము మరియు చెత్త లేకుండా ఉంచండి. శుభ్రం చేయడానికి మృదువైన, పొడి వస్త్రాన్ని ఉపయోగించండి.
• Avoid exposing the sensor to extreme temperatures, humidity, or direct sunlight.
• ఉపయోగంలో లేనప్పుడు పరికరాన్ని చల్లని, పొడి ప్రదేశంలో నిల్వ చేయండి.
• Protect the sensor from physical shocks or drops, as this can affect its calibration and internal components.
• Regularly check for software/firmware updates from the official WITMOTION webమీరు తాజా లక్షణాలు మరియు బగ్ పరిష్కారాలను కలిగి ఉన్నారని నిర్ధారించుకోవడానికి సైట్.
