3. คู่มือการใช้งาน
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 |
|---|---|---|
| ต่ำ | ต่ำ | ปิดเครื่อง |
| ต่ำ | สูง | 2% |
| สูง | ต่ำ | 20% |
| สูง | สูง | 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 |
|---|---|---|
| ต่ำ | ต่ำ | ฟิลเตอร์สีแดง |
| ต่ำ | สูง | ฟิลเตอร์สีฟ้า |
| สูง | ต่ำ | Clear (no filter) |
| สูง | สูง | ฟิลเตอร์สีเขียว |
3.3 ขั้นตอนการวัด
- 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. การบำรุงรักษา
The TCS230/TCS3200 Color Sensor Detector Module is a robust electronic component, but proper care ensures its longevity and accurate performance.

5 การแก้ไขปัญหา
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).
- ค่าที่อ่านได้ไม่ถูกต้องหรือไม่เสถียร:
- สภาพแสง: Ensure consistent and adequate lighting on the object. Ambient light can interfere with readings; consider using the onboard LEDs or a controlled light source.
