Abstract

The advancement of household water pump technology utilizing induction motors provides numerous benefits, such as efficiency and low cost, but also faces challenges like high inrush current. This study demonstrates the necessity of voltage reduction methods to address high inrush currents that can impact home electrical systems. Testing reveals that the device's error percentage is 0.31%, indicating good performance. The DHT22 and PZEM sensors operate optimally in detecting temperature and current, and controlling relays and water pumps according to the specified thresholds, achieving a 100% system success rate. These results confirm that the system operates as expected according to the specifications.

Abstract

The ever-increasing need for clean water requires innovation in water quality management and monitoring. This research aims to design and develop a water turbidity monitoring tool and an automatic water pump based on the Internet of Things (IoT) using the ESP32 microcontroller. The main objectives of this research include implementing ESP32 as the main controller, developing a system that can detect and monitor water turbidity levels in real-time using a turbidity sensor. The research results show that the designed tool is able to work well, with a measurement error rate of less than 5%, which shows high accuracy. The turbidity sensor and ultrasonic sensor work optimally, able to determine whether the water is clear or cloudy, and control the water pump automatically. The water pump will stop if the water level exceeds 32 cm or the water turbidity value exceeds 20 NTU. This system successfully meets the initial research objectives, offering an efficient and reliable solution for water quality management.

Abstract

Innovative technology solutions are developed to help patients manage their medication more effectively. Diabetes is a chronic disease that requires regular monitoring of blood sugar levels and proper regulation of medication consumption. This system is designed to assist diabetics in remembering when to take their medication and to ensure the correct dosage in accordance with the doctor’s recommendations. It utilizes an IoT device connected to a mobile application or web-based platform, allowing users to receive notifications at predetermined times. Additionally, the system includes patient condition monitoring features, such as blood sugar level tracking synchronized with measurement devices. The collected data is transmitted in real-time to the application, enabling both patients and medical personnel to monitor treatment progress and make necessary adjustments. Through the integration of IoT, this system not only enhances patient adherence to medication schedules but also provides better analysis of medication effectiveness and potential risks, thereby minimizing negligence in medication consumption. The implementation of this technology has the potential to significantly improve the quality of life for individuals with diabetes.

Abstract

The management of water resources in dams relies heavily on reliable control and monitoring systems to prevent disasters such as floods and droughts. This research aims to design and build an automatic control system for dam sluice gates and real-time water level monitoring based on the Internet of Things (IoT). This system uses ultrasonic sensors to measure water levels, microcontrollers as control centers, and servo motors to automatically adjust the sluice gate opening and closing based on a predetermined height threshold. Water level data is sent and displayed in real-time through an IoT platform so that it can be accessed by users via smartphones or computers\cite{alfariski2022automatic}. The test results show that the system is able to monitor the water level with good accuracy and control the floodgates responsively according to actual conditions in the field. Thus, this system is expected to improve the efficiency of dam management and provide early information for disaster mitigation
