🔧 What is an Automatic Weight Measuring Machine?

An automatic weight machine is an embedded system that uses sensors to measure weight and display/store the result. In an e-commerce setup, this machine can:

• Measure product/package weight before dispatch

• Automatically calculate shipping cost

• Integrate with inventory management or shipping platforms

• Print labels or send data to the cloud

This solution is ideal for warehouses, courier centers, or even small online sellers looking to automate their order processing.
