The Analog TDS Sensor Module is a reliable and easy-to-use solution for measuring Total Dissolved Solids in water, helping you assess water quality and cleanliness in real time. This sensor is widely used for testing domestic drinking water, hydroponic nutrient solutions, aquariums, and homemade water filtration systems, giving hobbyists and DIY builders a simple way to monitor how many dissolved solids are present in a liquid. The higher the TDS reading, the more dissolved solids the water contains, making this module a valuable tool for water quality analysis and health-conscious filtration projects.
Compatible with Arduino, ESP32, and Raspberry Pi, this plug-and-play module outputs an analog voltage signal proportional to the TDS level, requiring no soldering to get started. It uses an AC excitation signal to prevent probe polarization, which extends probe life and improves signal stability over long-term use. The included waterproof probe can be safely immersed in water for extended monitoring, though it should be kept away from container edges and away from water above 55°C to ensure accurate readings.
Whether you’re building a smart water quality monitor, a hydroponic nutrient tracker, or a DIY water filter testing rig, this TDS sensor module offers dependable, beginner-friendly performance backed by a wide voltage range that works with both 3.3V and 5V systems.
