| Summary: | Turbidity is one of the important parameter for the determination of water quality.
The current existing method of measuring turbidity of water could come in bulky
size or small portable turbidity meter. The ability to handle many samples and
implementation of on-line monitoring is limited for such devices while some do not
support this feature. Taking measurements would be laborious and time consuming
especially when the sources of samples are located in remote places which are
difficult to be accessed by human.
In this research, an alternative turbidity measurement system called the “Optical
Transmission-Based Water Turbidity Measurement System” is designed and its
performance is analysed and compared to the measurement from a standard turbidity
meter. The concept of the proposed measurement system is to make the turbidity
measurement remote, easy to handle and more flexible. The use of fibre optic as the
element of carrying light enables measurement taken at the source of sample but
could be remotely controlled from other place by the user. The design for the fibre
optic set-up, transmitter circuit, receiver circuit and signal conditioning circuit were covered. The assembly program for Peripheral Interface Controller (PIC) was also
created. |
