Most commonly used load cells have strain gauges connected in a Wheatstone bridge. FIGURE 2. This is a full-bridge arrangement for a load cell, in which two strain gauges have a positive change to ...

The Wheatstone bridge load cell circuit generates a tiny voltage difference that’s far too small for an ESP32 to measure, so in between the pair is an Avia Semiconductor HX711 strain gauge ...

The cells are typically arranged in a Wheatstone Bridge configuration to produce an electrical output whose polarity depends on whether the load cell is loaded in compression or tension.
