Product Description
The Seeed Studio Grove TDS Sensor/Meter is a water quality sensor designed to measure Total Dissolved Solids (TDS) in aqueous solutions. TDS is an important parameter that indicates the level of dissolved ionic compounds in water, which can correlate with water purity and suitability for consumption or industrial use. The sensor module features a Grove connector for quick plug-and-play integration with compatible base shields and microcontroller platforms like Arduino, ESP32, and Raspberry Pi with appropriate adapters.
By outputting an analog voltage proportional to TDS levels, this sensor allows microcontrollers to read and convert water quality data into meaningful values for monitoring, logging, and control purposes. It’s commonly used in IoT water quality monitoring stations, aquaculture systems, drinking water purifiers, environmental sensing projects, and research applications.
