Abstract

This research aims to produce an IoT-based Fiber Optical Chemical Sensor (FOCS) sensor system for pH detection using an ESP-32 microcontroller. The chemical sensor developed uses an optical fiber medium with a light transceiver technique. By utilizing the properties of light on optical fibers and by using SFP XXXX transceivers a voltage change data is obtained which is then sent and processed by the ESP-32 microcontroller so that it can be displayed on a screen and will be displayed on a smartphone in the form of measured pH prices. The tool made can be implemented for various groups, especially farmers with additional features.
