Firstly, we hava come out an initial design for holding the sensor, and we use the clip to mount it to a vertical surface to do some preliminary tests.
Latest Result
We have obtained some result for different turbidity level as shown below:
Existing problems
The data that obtained from spectroscopy sensor is not constant each time.
For similar Turbidty level, the intensity at some specfic wavelength could varied hugely (roughly double)
