Abstract: In this study, we report the development results of an electric double layer capacitor (EDLC) as a power supply system and a novel water level sensor to monitor water level of a rice field.

This project is a real-time water tank monitoring system using Arduino + Python + Flask + Web Visualization. It captures hourly water level data, stores it in JSON format, and syncs to a beautiful ...

In a tropical climate city such as Hong Kong, heavy rain is common. Apart from thunderstorms, Hong Kong also experiences typhoons in summer and fall. It is not unusual to have floods over the ...

This Arduino library provides a convenient and easy-to-use interface for the PH4502C sensor, allowing you to effortlessly integrate it into your Arduino projects. The PH4502C sensor is a ...
