It can detect and differentiate between moving, micro-moving, and stationary human targets within its operational range. The module provides data on distance, angle, and speed of detected targets, which can be processed by a connected MCU for various smart applications.
5. Maintenance
- Keep the module dry and clean. Avoid exposure to moisture, dust, and corrosive substances.
- Operate within the specified temperature range (-40°C to 85°C) to ensure optimal performance and longevity.
- Avoid physical impact or excessive force on the module.
- Regularly check connections for secure fit.
6. Troubleshooting
If the module is not functioning as expected, consider the following:
- No detection: Verify power supply (5V) and ground connections. Ensure the module is correctly wired to the MCU (TX to RX, RX to TX). Check for any obstructions in the detection area.
- Inaccurate readings: Ensure the module is mounted securely and not vibrating. Confirm that the environment is within the specified operating conditions.
- Communication issues: Check the serial communication settings (baud rate, parity, stop bits) on your MCU to match the module's requirements.
For persistent issues, please refer to the technical support section.
