Taking a break

 We're taking a break moving shop and hope to be back soon. We will ship orders on 2018-07-25. 

The turbidity sensor detects water quality by measuring level of turbidity. It is able to detect suspended particles in water by measuring the light transmittance and scattering rate which changes with the amount of total suspended solids (TSS) in water. As the TTS increases, the liquid turbidity level increases. This sensor have both analog and digital signal output modes. You can select the mode according to the MCU as threshold is adjustable in digital signal mode. Turbidity sensors can be used in measurement of water quality in rivers and streams, wastewater and effluent measurements, sediment transport research and laboratory measurements.   Please note that the top of probe is not waterproof!
