Abstract

Remote chemical pH monitoring using Internet of thing (IoT) node is a system that provides pH reading of chemicals from the cloud or Internet and can be monitored from anywhere and everywhere using smartphone or web page. The pH data is transmitted to the Internet using IoT node device that interpreted the analog pH sensor output to readable data. This system is designed to replace manual pH level monitoring operation that used human power to collect pH readings. The system consists of an IoT node device, a web page and an Android mobile application. The IoT node device is equipped with microcontroller and a Wi-Fi module. The microcontroller will process the sensor data and transmit the pH data to an IoT server every 30s via Wi-Fi module. Every 30s the web page will update the pH data in form of chart and table. The Android application is linked to the web page server so every update to web page will update the Android application too. This automated system can reduce human error and negligence that result in false and inconsistent reading. Furthermore, the web application is equipped with Microsoft Excel data export so that all the data can be saved and viewed in local computer for private record. With this system, a consistent worldwide-access remote pH monitoring is no longer a fantasy.
