modern agriculture, the integration of technology is becoming increasingly pivotal for enhancing livestock security and efficiency. This project, titled “Design and Implement Smart livestock monitoring system,” aims to develop a comprehensive solution utilizing three ESP32CAMs and three ultrasonic sensors to safeguard agricultural assets and improve real-time monitoring. The core objectives of this project are twofold: first, to detect and alert the presence of people or other animals approaching the farm, and second, to provide farmers with instant video access for remote monitoring and assessment. The system operates by strategically placing ESP32CAMs at key points within the farm, equipped with ultrasonic sensors for precise detection. Upon detecting any potential intrusion, the system triggers an immediate SMS notification to the farmer, allowing for rapid response to potential threats. Furthermore, the ESP32-CAMs continuously capture and store video footage, which can be accessed remotely by the farmer at any time. This feature not only aids in security but also serves as a valuable tool for farm management and surveillance. The " Design and Implement Smart livestock Monitoring System” represents an innovative and cost-effective solution that enhances livestock security, reduces potential losses, and empowers farmers with real-time insights into their agricultural operations. By leveraging the capabilities of ESP32-CAMs and ultrasonic sensors, this project contributes to the modernization of agriculture, ensuring its sustainability and productivity.

The design and implementation of a 3-phase motor using a single-phase power supply with the aid of a capacitor addresses a key challenge in electrical motor systems, particularly in areas where 3-phase power is unavailable or impractical. 3-phase motors are known for their efficiency, reliability, and smooth operation, which makes them ideal for industrial applications. However, many environments only provide single-phase power, necessitating conversion techniques to operate these motors effectively. This project explores the development of a phase conversion method using a start and run capacitor to create the required phase shift that allows a 3-phase motor to run on a singlephase power source. Capacitors are used to generate an artificial phase, thereby creating a pseudo-3-phase system. The design focuses on the optimal selection of capacitors to ensure the balance between phases, improve motor efficiency, and reduce vibration and noise. This approach is both cost-effective and practical for small to medium-scale motor applications. The implementation involved the detailed analysis of the motor's electrical requirements, the calculation of capacitance values necessary to achieve proper phase shifting, and the design of the connection circuitry. Testing and performance evaluation showed that while the 3-phase motor operating with a single-phase input through a capacitor arrangement does not achieve the full performance of a true 3-phase power system, it is still adequate for many applications where high power or precision control is not critical. This system provides a practical and affordable solution for running 3-phase motors in environments constrained by single-phase power supplies, making it a viable option for industries and small businesses like development country as Rwanda.

Abstract Transmission line is the most important part of the power system. Transmission lines a principal amount of power. the major role of a transmission line is to transmit electric power from the source area to the distribution network. The exploded between limited production, and a tremendous claim has grown the focus on minimizing power losses. Losses like transmission loss and also conjecture factors as like as physical losses to various technical losses, another thing is the primary factor it has a reactive power and voltage deviation are momentous in the long-range transmission power line. In essentially, fault analysis is a very focusing issue in power system engineering to clear fault in short time and re-establish power system as quickly as possible on very minimum interruption. However, the fault detection that interrupts the transmission line is itself challenging task to investigate fault as well as improving the reliability of the system. The transmission line is susceptible given all parameters that connect the whole power system. This paper presents a review of transmission line fault detection.

This project presents the design and implementation of automated Gas leak detector and ventilation system, aimed at enhancing safety in environments where LPG is used. The system utilizes an Arduino Uno microcontroller, an MQ2 gas sensor, an SG90 micro servo motor, a fan, and a buzzer to detect gas leaks, alert users, and initiate a ventilation process. The MQ2 sensor detects LPG concentrations and triggers the fan and buzzer when dangerous levels are detected, ensuring timely mitigation of potential hazards. Key findings from the system's evaluation showed that the gas detection mechanism was effective, with the MQ2 sensor detecting LPG concentrations as low as 500 ppm and triggering the fan and alarm at 1000 ppm. The system demonstrated a response time of less than 5 seconds, and the ventilation system reduced gas concentration by 50% within the first 5 minutes of operation. The components used, including the servo motor and fan, functioned reliably throughout the testing phase. The project successfully meets its objective of responsive, and reliable LPG leak detection system. However, improvements such as enhanced sensor sensitivity, integration of wireless communication for remote monitoring, and the addition of features like automatic gas supply shutdown are recommended for future work to broaden the system’s applicability and functionality.
