The TDS sensor detects water conductivity. The Arduino reads this analog signal and converts it to digital. A calibrated formula calculates the TDS value in ppm. The LCD displays the real-time TDS ...

This Arduino-ESP8266 system tracks pH, TDS, flow rate, water level, and temperature using multiple sensors. Data is sent to ThingSpeak for real-time monitoring 📊. Helps in water purification, ...

The system is designed with a control center using the Arduino UNO R3 board. The system is equipped with GP2Y0A21 proximity sensor as a water level detector, TDS sensor as a detector of electrical ...

Hydroponics is a new breakthrough in farming because it no longer uses soil as a planting medium, and uses water instead. In the hydroponic system, the fertilizer used is mixed into water, which is ...
