Generic Sample Weighing Load Cell 0–5 kg (45 mm) - Aluminum Alloy

This load cell outputs a low-level analog millivolt signal proportional to the applied load. You cannot connect it directly to a microcontroller. You must use a dedicated instrumentation amplifier module, such as the HX711, which provides excitation voltage, amplifies the tiny signal, and converts it to a digital output readable via a serial interface.

A typical excitation voltage of 5V DC is recommended, which is supplied by the amplifier module (e.g., HX711). The load cell has a 4-wire connection: Red (Excitation+), Black (Excitation-), Green (Signal+), and White (Signal-). You must connect these wires to the corresponding terminals on your amplifier board, following its specific pinout diagram.

No, you must not exceed the rated capacity of 5kg. Applying an overload can cause permanent mechanical damage or calibration drift, leading to inaccurate readings and potential sensor failure. Always select a load cell with a capacity slightly above your maximum expected operating load for safety and longevity.
