The TDS Conductivity Sensor allows you to accurately measure the concentration of dissolved solids in water, expressed in PPM (parts per million). It’s perfect for monitoring drinking water quality, aquariums, hydroponics, and environmental testing.

With an easy-to-use analog output, it can be directly connected to Arduino, ESP32, and other microcontrollers for real-time monitoring.

Features:

• Measures TDS (Total Dissolved Solids) in PPM

• Wide measuring range: 0 – 1000 ppm (typical models)

• Analog output for microcontroller compatibility

• Waterproof probe for long-term immersion

• Compact and easy to integrate into projects

• Low power consumption

Specifications:

• Supply Voltage: 3.3V – 5.5V

• Output Signal: Analog voltage

• Measuring Range: 0 – 1000 ppm (typical)

• Accuracy: ±10% F.S. at 25°C

• Cable Length: ~1 meter (varies by model)

• Probe Material: Stainless steel electrodes

• Waterproof: Yes (probe only)

Applications:

• Drinking water quality monitoring

• Aquariums and fish tanks

• Hydroponics and nutrient control

• Environmental water testing

• Water filtration and purification systems
