200kg load cell sensor plus HX711 Amplifier

This load cell is a force sensing module - a carefully designed metal structure, with small elements called strain gauges mounted in precise locations on the structure. Load cells are designed to measure a specific force, and ignore other forces being applied. The electrical signal output by the load cell is very small and requires specialized amplification. Load cells are designed to measure force in one direction. They will often measure force in other directions, but the sensor sensitivity will be different, since parts of the load cell operating under compression are now in tension, and vice versa.

Full-scale output voltage = excitation voltage x sensitivity 2.0mv / v

For example: the supply voltage is 5v times the sensitivity 2.0mv/v = full scale 10mv
