Description of TDS Sensor For Water Quality
Quick Overview
The TDS (Total Dissolved Solids) Sensor for Water Quality is engineered to measure the concentration of dissolved ionized solids in a liquid, mainly water. This sensor is invaluable for applications that require monitoring water purity, like water filtration systems, aquaculture, and hydroponics.
How It Works
The sensor features a pair of electrodes immersed in water. A voltage is applied across the electrodes. The electrical conductivity between the electrodes is measured, which is directly proportional to the TDS value. The raw conductivity data can then be converted into TDS values in ppm (parts per million) using a connected microcontroller.
Technical Specification
- Operating Voltage: 3.3V to 5V DC
- Output Signal: Analog
- Material: Stainless steel electrodes
- TDS Range: 0 to 2000 ppm
