50kg Half-Bridge Load Cell | Human Scale Weight Sensor | For Arduino Projects

This 50kg load cell is a half-bridge strain gauge. It's the main sensing part for your DIY scale projects. When you apply force, its resistance changes. This lets you measure weight. It works best in sets, often with an Arduino and an amplifier. Features and Benefits - 50kg capacity per sensor - You can build a scale with a higher total capacity. Just combine several load cells. - Half-bridge design - You can wire four of these sensors together. This makes a full-bridge circuit for steady, accurate measurements. - Compact aluminum alloy body - Its small size makes it easy to put into thin, low-profile scale designs. - Simple 3-wire setup - Wires are easy to connect to an amplifier board. An HX711 works for your Arduino project. Applications - Building a custom digital bathroom scale (use four sensors). - Making a small postal or kitchen scale for exact measurements. - Testing smart shelves or inventory systems that track object weight. What It Is This is a 50kg Half-Bridge Load Cell, a human scale weight sensor designed for Arduino projects. It is a type of transducer made from metal, specifically a half-bridge strain gauge. Load cells convert mechanical force into an electrical signal. As a half-bridge unit, it typically works in conjunction with other load cells or a Wheatstone bridge circuit to provide a complete measurement of force or weight. Key Uses & Applications This load cell is ideal for various Arduino-based projects requiring weight measurement up to 50 kg. Its primary application is as a human scale weight sensor, allowing for the construction of custom weighing platforms or smart scales. Other uses include hobbyist robotics, DIY force measurement systems, and educational projects where understanding how a load cell works is key. It's suitable for small-scale industrial applications or personal projects where precise weight monitoring is needed. How to Choose When selecting a load cell, consider the required load capacity; this model handles up to 50 kg. Ensure compatibility with your control system, as this load cell is designed for Arduino. The sensor type, a half-bridge strain gauge, dictates how it integrates into a circuit; a full bridge setup often requires multiple half-bridge cells. Material, in this case metal, indicates durability. Always match the load cell's specifications to your project's demands for accurate and reliable measurements. Grit / Spec Guide This 50kg Half-Bridge Load Cell features a metal construction and a load capacity of 50 kg. It is a half-bridge strain gauge sensor, meaning it measures strain as a change in electrical resistance. The output signal is typically very small and requires amplification by an appropriate amplifier or ADC module, often operating with a 5V or 10V excitation voltage. Understanding how load cells work involves connecting the strain gauge to a measurement circuit to detect minute changes in resistance under load. Care & Safety Handle the load cell with care to avoid damage to the metal body or the internal strain gauge. Do not exceed the 50 kg load capacity, as this can permanently damage the sensor. Ensure proper electrical connections when integrating with Arduino projects, paying attention to voltage requirements for the strain-gauge. Protect the cable from sharp edges or excessive bending. Calibrate the load cell regularly to maintain accuracy in your weighing applications.
