TS-300B Water Turbidity Sensor with Cable

The TS-300B Water Turbidity Sensor detects how cloudy or clear water is by measuring suspended particles inside it. Water turbidity sensors like this one send an analog signal that rises or falls based on particle concentration. Connect it to your Arduino or ESP32 board and read changing voltage values using analogRead. The sensor uses an optical method (light transmission through water) to judge clarity.

This water sensor module gives an analog voltage output, which means you read a raw number from your ADC (analog-to-digital converter) and map it to a turbidity level. One non-obvious fact is that the output curve is not perfectly linear across the full range, so you will need two or three calibration points using water samples of known clarity for reliable readings. The ts 300b turbidity sensor does not give you a pre-calculated NTU (Nephelometric Turbidity Unit) value directly.

The TS-300B sensor module works with Arduino Uno and ESP32 boards using any standard IDE like the Arduino IDE. Students building water quality monitors, hobbyists testing aquarium filters, and water sampling use this sensor. Connect the power the board at 5V, and read the analog pin to get your first reading in under five minutes. StemVolt provides this sensor with trusted quality, ensuring reliable performance and easy usability.
