The S-TUR033 Turbidity Sensor is a patented product with independent intellectual property rights, custom-developed for online monitoring of drinking water quality. Adopting the 90° light scattering detection principle, it features a unique photoelectric receiving structure and an automatic temperature-light compensation method, greatly enhancing the precision and accuracy of turbidity detection. Equipped with a built-in ARM7 data processor and an efficient digital filtering algorithm, the sensor effectively avoids noise interference. It adopts the standard Modbus digital signal output, facilitating easy integration into computer monitoring systems by users.
