Turbidity sensor monitoring water quality turbidity value sewage oacute;w TSW-20M sensor module 1. This turbidity sensor adopts optical principle to detect the turbidity of liquid solution. 2. This module converts the current sensor signal to the output voltage module. The lower the output voltage, the higher the turbidity value. 3. The module adopts high-quality electronic components, ensuring the accuracy of turbidity measurement. 4. Simple structure, easy to wire and operate. 5. Suitable for turbidity measurement and control of washing machine, dishwasher, industrial control and environmental wastewater collection. Specification: The turbidity sensor adopts the optical principle, which determines the turbidity by combining the transmittance and dissipation rate of the liquid solution. Equipped with a waterproof probe, this module is mainly used to test the turbidity of washing machines, dishwashers and other appliances. And it can be also used in electronic design, graduate design, electronic competition experiments and other applications. Features: 1.
