3. Instrukcja obsługi
The TCS230/TCS3200 module operates by selecting specific color filters (Red, Green, Blue, or Clear) and a frequency scaling factor. The sensor then outputs a square wave whose frequency is directly proportional to the intensity of the detected light.
3.1 Frequency Scaling (S0, S1)
The S0 and S1 pins control the output frequency scaling. This allows for adjusting the output frequency range to suit different microcontroller input capabilities or measurement resolutions.
| S0 | S1 | Output Frequency Scaling |
|---|---|---|
| NISKI | NISKI | Wyłączanie zasilania |
| NISKI | WYSOKI | 2% |
| WYSOKI | NISKI | 20% |
| WYSOKI | WYSOKI | 100% |
3.2 Color Filter Selection (S2, S3)
The S2 and S3 pins control which color filter (red, green, blue, or clear) is active, allowing the sensor to measure the intensity of specific color components.
| S2 | S3 | Photodiode Type |
|---|---|---|
| NISKI | NISKI | Filtr czerwony |
| NISKI | WYSOKI | Filtr niebieski |
| WYSOKI | NISKI | Clear (no filter) |
| WYSOKI | WYSOKI | Zielony filtr |
3.3 Procedura pomiarowa
- Set the desired output frequency scaling using S0 and S1.
- Select the color filter (Red, Green, Blue, or Clear) using S2 and S3.
- Position the object to be measured approximately 10mm from the sensor for optimal results.
- Read the frequency output from the OUT pin using your microcontroller's interrupt or pulse-counting capabilities.
- Repeat for other color filters to obtain RGB values.
4. Konserwacja
The TCS230/TCS3200 Color Sensor Detector Module is a robust electronic component, but proper care ensures its longevity and accurate performance.
- Zachowaj czystosc: Regularly clean the sensor's optical window with a soft, dry, lint-free cloth to prevent dust or smudges from affecting readings. Avoid abrasive materials or harsh chemicals.

5. Rozwiązywanie Problemów
If you encounter issues with your TCS230/TCS3200 module, consider the following troubleshooting steps:
- No Output Frequency:
- Verify power connections (VCC and GND) are correct and within the 3V-5V range.
- Ensure the OE (Output Enable) pin is connected to GND or driven LOW by your microcontroller.
- Check all wiring for continuity and correct pin assignments.
- Confirm that S0 and S1 are not set to 'Power Down' mode (LOW, LOW).
- Incorrect or Unstable Readings:
- Warunki oświetleniowe: Ensure consistent and adequate lighting on the object. Ambient light can interfere with readings; consider using the onboard LEDs or a controlled light source.
- Odległość wykrywania: Maintain the optimal detection distance of approximately 10mm. Too close or too far can affect accuracy.
- Czystość czujnika: Clean the sensor's optical window as described in the Maintenance section.
- Frequency Scaling: Experiment with different frequency scaling settings (S0, S1) to find the best range for your application.
- Logika kodu: Review your microcontroller code to ensure correct reading of the frequency and proper interpretation of color values.
- Module Not Recognized by Microcontroller:
- Double-check all digital pin connections for S0, S1, S2, S3, and OUT.
- Ensure your microcontroller's pins are configured correctly as inputs/outputs.
