Detailed Description:

The 5KG Load Cell Weight Sensor is a fundamental component for any project that requires precise force or weight measurement. This high-quality strain gauge is a transducer that translates an applied force into a proportional electrical signal, making it the perfect choice for building electronic scales, robotics, or any system for weight monitoring. Constructed from a durable aluminum alloy, this mini force sensor is designed to withstand compression and bending, ensuring a reliable and repeatable output over a long lifespan.

With a weighing capacity of up to 5KG, it is ideal for a variety of small- to medium-scale applications, such as a smart kitchen scale, an automated pet feeder, or a robotic gripper with force feedback. A key technical detail to note is that the sensor's output is a very small analog signal in the millivolt range. To effectively use this sensor, it must be paired with an analog-to-digital converter (ADC) module like the HX711, which amplifies the signal and converts it into a high-resolution digital value that can be easily read by a microcontroller like an Arduino or Raspberry Pi. Its straightforward four-wire interface, which forms a Wheatstone bridge, simplifies integration into your custom circuitry. Whether you're a student working on a science fair project or a seasoned maker, the 5KG load cell provides a robust and accurate foundation for your weight-sensing applications.

This 5KG Load Cell is a compact and lightweight strain gauge-based weight sensor made from anodized aluminum alloy. Internally structured with Wheatstone bridge circuitry, it provides stable analog output proportional to applied load. When used with an HX711 amplifier, it can easily interface with Arduino, Raspberry Pi, or microcontroller platforms.

Designed for applications like digital weighing systems, smart load monitors, and IoT automation, it offers high accuracy, good linearity, and long mechanical life. It has pre-soldered 4 wires for easy setup and M3 mounting holes for quick installation.
