About this item

The DFRobot Gravity Analog Turbidity Sensor is a practical and easy-to-use module designed to measure the turbidity or clarity of water. Turbidity is an important parameter in water quality monitoring, representing the amount of suspended particles, such as sediment, algae, or pollutants, present in a liquid. This sensor allows you to detect and quantify water cloudiness using infrared light and photodetectors. The sensor works by measuring the amount of light that is scattered by particles in the water. As turbidity increases, more light is scattered, and the sensor converts this into an analog voltage signal that can be read by any Arduino or compatible analog input device. It is widely used in DIY environmental monitoring stations, aquariums, water filtration systems, and hydroponics. Encased in a waterproof probe, the sensor is safe for immersion in fresh water and includes an amplifier board with a Gravity-compatible interface for simple connection and fast prototyping. With reliable performance and minimal setup, it’s ideal for hobbyists, educators, and developers looking to add real-time water quality sensing to their projects.
