Water is a vital resource used in various fields, but maintaining water levels in tanks is often inefficient, leading to waste or damage. To address this, an automatic water level control system is designed using an HC-SR04 ultrasonic sensor, Arduino Uno, and L298N motor driver with a PID control algorithm. Testing shows the system maintains the water level close to the setpoint with fast response, low overshoot, and minimal steady-state error.

Liquid waste pollution poses a serious threat to human health and aquatic ecosystems. Waste from industry, households, and agriculture is often discharged without proper treatment, leading to contamination by hazardous substances. This reduces water quality, endangers biodiversity, and disrupts ecosystem balance. To address this, an innovative liquid waste filtration system powered by solar panels and integrated with Internet of Things (IoT) technology using the MQTT protocol is proposed. This system not only filters waste but also monitors water quality in real time, promoting a clean and sustainable environment.

To support environmental sustainability, this research proposes an electric vehicle charging system that combines solar energy and piezoelectric technology. Solar panels charge vehicle batteries when parked, while piezoelectric systems generate energy from mechanical pressure as vehicles move. Integrated with artificial intelligence, the system optimizes energy management and monitoring, reducing carbon emissions and dependence on fossil fuels. This innovation promotes green transportation and highlights the role of technology in creating sustainable solutions.
