TDS / EC Water Quality Sensor
—A TDS/EC sensor measures total dissolved solids and electrical conductivity in water, the standard nutrient measurement in hydroponics.
Specifications
- Measures TDS in ppm and EC in µS/cm
- Range typically 0-1000 ppm
- Waterproof probe on a lead
- Analogue voltage output
- 3.3-5.5V supply
- Temperature compensation recommended
What you can build with the TDS / EC Water Quality Sensor
- Hydroponic nutrient monitoring
- Drinking water quality checks
- Aquarium and pond salinity
- Rainwater and bore water testing
Compatibility
Works with Arduino, ESP32 and Pico via analogue input; a Pi needs an external ADC. Pair it with a DS18B20 for temperature compensation — conductivity readings shift several percent per degree.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
