Analog TDS Water Quality Sensor Module for Arduino, Raspberry Pi & ESP32

Analog TDS Water Quality Sensor Module is a water quality sensor that measures total dissolved solids (TDS) in water, making it useful for real-time monitoring of relative purity and mineral content in hydroponics, aquariums, drinking water systems, filtration projects, and environmental testing. Its analog output makes it easy to read from Arduino and ESP32 boards and integrate into Raspberry Pi-based monitoring setups, helping makers build water testers, smart irrigation systems, and data-logging prototypes that track changing water conditions over time. It is well suited to DIY water analyzers, IoT alerts, and robotics or home automation projects that respond to changing water quality.
