Ground Scale Management System

This is a Windows application I built for a recycling company that operates a ground scale — the kind trucks drive onto to be weighed. The scale itself outputs the weight reading over a serial port. The application reads that reading directly, logs it against the truck and driver entering or leaving the site, and prints an invoice at the counter.

Before the project, the operator was reading the number off the scale’s display and typing it into a spreadsheet by hand. That step is gone now.

What it handles

• Live weight reading from the scale over RS232 — no manual entry.
• Manual fallback when the scale is being serviced or unreachable.
• Truck, driver, and customer records linked to every weighing.
• Custom invoices and entry/exit receipts printed on the spot.
• Daily, monthly, and yearly reports exportable to Excel.
• User roles so operators can only record weights, while managers can edit historical records.

Tech

• C# Windows desktop application.
• Talks to the scale over a serial port (RS232).
• Local database with periodic Excel backups so the accountant can pick them up without opening the app.
