Load Sensor (Weight Sensor) 0-50kg

Half-bridge load cell (strain gauge) rated at 50 kg, suitable for building digital scales or force measurement systems. This compact sensor integrates a strain gauge in a partial bridge configuration, delivering an analog output proportional to the applied load.

It connects directly to amplification modules like the HX711 for interfacing with Arduino, Raspberry Pi, or ESP32. Multiple sensors can be used simultaneously to distribute the load and increase total measurement capacity.
