Title

Removal of redundance in fuel procurement in private organisation.

Abstract

Fuel management in private firms in Zimbabwe has previously relied on multi-level authorization and paper-based manual systems with the use of fuel coupons, which has led to inefficiency, delays, and vulnerability to fuel theft and abuse. This project proposes and implements an automated, centrally controlled fuel purchasing system to address these problems. The system integrates user authentication, online monitoring of fuel levels, and controlled dispensing through embedded systems and a cloudless local database system. Ethereal to it is an ESP32 microcontroller tied with a keypad, ultrasonic level sensor, LCD display, and a pump which is solenoid valve operated, all functioning together to manage safe and priority access to fuel resources. The users are recognized by their unique ID and PIN, and his/her fuel allocation is verified from a MySQL database which is accessed using PHP scripts. Dispensing is authorized only if users meet allocation and priority requirements. The system keeps the database up to date to reflect outstanding allocations and keeps all transactions, to avoid overuse and enable accountability. The solution is advantageous in that it significantly improves efficiency, reduces operation downtime, reduces human error, and improves fuel distribution transparency, and thus constitutes a sustainable and scalable model of digital resource management for developing environments.
