What are load cells?

A load cell is like a super-smart scale that can tell how heavy something is, but it doesn’t need to be on the floor.

Imagine you have a seesaw at the playground. When one kid sits on one end, the other side goes down. That’s how weight works: more weight means more force pushing down. A load cell uses this idea, but instead of a seesaw, it has special parts that change shape when something heavy is placed on them.

Think of a load cell like a spring inside a toy. When you press down on the toy, the spring gets squished, and the more weight you put on it, the more it squishes. The load cell measures how much it squishes to figure out how heavy something is.

These smart scales are used in places like grocery stores, factories, and even your phone! They help weigh packages, lift heavy things with cranes, or track how much you eat, all without needing a big scale on the floor.
