Monitor your water quality in real time with the Arduino-compatible TDS Sensor Water Conductivity Module. Designed for DIY water monitoring projects, this module measures the Total Dissolved Solids (TDS) in water—an important indicator of purity and cleanliness. Perfect for home water testing, hydroponic systems, aquariums, and environmental experiments.

Key Features

  • Wide voltage range (3.3–5.5V) for flexible compatibility with Arduino and other microcontrollers.
  • Analog signal output (0–2.3V) supports both 3.3V and 5V systems.
  • AC signal excitation design prevents probe polarization, enhances stability, and extends probe life.
  • Waterproof probe allows for long-term submersion and continuous water quality monitoring.
  • Plug-and-play setup for quick installation and easy integration—no soldering required.
