Abstract
This research aims to develop fiber optic sensors that can be used to measure acid rain levels. This fiber optic sensor uses the evanescent wave type method. SFP (Small Form-factor Pluggable) Transceiver with a wavelength of 1310nm is used as a fiber optic transmitter and receiver, while the Optical Power Meter (OPM) is used as a validator to test the developed sensor capability. The measurement results indicate the presence of loses successfully detected by OPM and SFP Transceiver. It appears that the maximum value of pH level has been successfully detected with a range of values of 8.72 dBm to 9.75 dBm and 8.7 dBm to 9.74 dBm respectively using SFP Transceiver and OPM. Good results during the validation process show that the fiber optic sensor has successfully worked with a strong correlation of 0.78 to monitor acid rain levels.
