4. Postavljanje i integracija

4.1 Napajanje

The B93D module requires a stable DC power supply within the range of 2.5V to 3.3V. Ensure your power source can provide sufficient current for stable operation. If your system's voltage is higher, a power converter (LDO) may be used to step down the voltage to the required range.

4.2 Električni priključak

The module features a multi-pin connector for power and data communication. Typically, these modules use a serial communication interface (e.g., UART/TTL) for sending commands and receiving measurement data. Refer to the module's pinout diagram (not provided in source, but implied by connector) for correct wiring:

• VCC: Power input (DC 2.5V-3.3V)
• GND: Ground
• TX: Transmit data (output from module)
• RX: Receive data (input to module)

Connect the module to your microcontroller or processing unit according to the pinout. Ensure proper voltage levels for data lines to prevent damage.

4.3 Fizička montaža

The module's compact size (64x40x18mm) allows for flexible integration. Secure the module using appropriate mounting hardware through the designated mounting holes on the PCB. Ensure the laser emission and reception lenses are unobstructed and clean for accurate measurements.

5. Uputstvo za upotrebu

5.1 Princip mjerenja

The B93D module uses a laser-based time-of-flight or phase-shift principle to determine distance. A laser diode emits a green laser beam towards the target. The reflected light is then detected by a photo diode. By analyzing the time taken for the light to travel or the phase shift, the module calculates the distance to the target.

5.2 Initiating Measurements

To initiate a measurement, send the appropriate command via the serial interface (TX/RX pins) to the module. The specific command protocol will depend on the module's firmware. Upon receiving a measurement command, the module will emit a laser, perform the distance calculation, and then transmit the result back through the serial interface.

5.3 Interpreting Data Output

The module typically outputs measurement data in meters, as specified. The data format (e.g., ASCII string, binary) will be defined by the communication protocol. Your host system should be programmed to parse this data correctly.

5.4 Razmatranja životne sredine

• Radna temperatura: Ensure the module operates within its specified working temperature range of 0~40℃ (customizable to -10℃~50℃).
• Laserska sigurnost: This is a Class 3 laser product. Avoid direct eye exposure to the laser beam. Do not point the laser at reflective surfaces or at people.
• Target Surface: The accuracy and range can be affected by the target surface's reflectivity and texture. Highly reflective or very dark surfaces may impact performance.

6. Održavanje

• čišćenje: Keep the laser emission and reception lenses clean and free from dust, dirt, or smudges. Use a soft, lint-free cloth and, if necessary, a lens cleaning solution.
• Skladištenje: When not in use, store the module within the specified storage temperature range of -25~60℃ in a dry, dust-free environment.
• inspekcija: Periodically inspect the module for any physical damage or loose connections.

7. Otkrivanje problema

7.1 No Measurement Output

• Provjerite snagu: Provjerite da li modul prima ispravnu jačinu zvukatage (DC2.5~3.3V) and that the power supply is stable.
• Provjerite veze: Ensure all electrical connections (VCC, GND, TX, RX) are secure and correctly wired according to the pinout.
• Komunikacijski protokol: Confirm that the commands sent to the module and the parsing of its output adhere to the correct serial communication protocol.

7.2 Inaccurate or Unstable Measurements

• Čista sočiva: Ensure the laser emission and reception lenses are clean and free from obstructions.
• Target Surface: The target surface might be too reflective, too dark, or too far. Try measuring to a different, non-reflective, matte surface within the specified range.
• Uslovi okoline: Extreme temperatures (outside 0~40℃) or strong ambient light can affect accuracy.
• Vibracije: Excessive vibration during measurement can lead to unstable readings. Ensure the module is securely mounted.

7.3 Module Not Responding

• Ciklus napajanja: Disconnect and reconnect the power supply to reset the module.
• Voltage Provjerite: Potvrdite unos voltage is within the specified range. Incorrect voltage can cause the module to malfunction or not power on.
