Jul 17, 2017 · The sensor was fixed at 1.5 m above the seabed, and the frame was deployed in sufficiently deep water that it remained submerged at all stages of the tide. Its position was N W (see Fig. 3). A pressure sensor was fixed to the frame to allow the (tidally varying) water depth, z T, above the irradiance sensor to be monitored.

Water Quality Sensor : 3 Steps - Instructables

The turbidity sensor gave us trouble in that, when it was placed in water the values outputted would change rapidly instead of staying stable. These fluctuations we were defining the benchmark value for drinkable water, each time the sensor output fluctuated the benchmark value would have to be changed.

This method is subjective and works best in slow-moving, low turbidity natural waters. The best way to measure turbidity in a wide variety of samples is with a nephelometer, also known as a turbidity meter. Turbidity meters utilize a light and photo detector to measure light scatter, and read out in units of turbidity, such as nephelometric ...
