⚙️ Working Principle:
The Analog TDS Sensor works by measuring the electrical conductivity of water — the higher the ion concentration, the higher the conductivity, and thus the TDS value. The onboard signal conditioning circuit converts this analog voltage into a readable signal for microcontrollers.
By reading this data, users can determine water quality, detect pollution, and control automated purification systems.
