Detailed Description:
The 1KG Load Cell Weight Sensor is a precision component designed for projects that require accurate and reliable force or weight measurement. This strain gauge-based load sensor operates on the principle that its electrical resistance changes proportionally with the force applied to it, providing a consistent and repeatable signal. With a maximum capacity of 1KG, this sensor is a perfect fit for a variety of small-scale applications, including building a custom digital kitchen scale, a smart pet feeder, or a weight-sensing system for a miniature robot.
Constructed from a high-quality aluminum alloy, this sensor is both durable and lightweight, ensuring long-term stability and performance. Its standard four-wire configuration, which forms a Wheatstone bridge, allows for straightforward integration into your circuit. A key technical consideration is that the output of the load cell is a tiny analog signal in the millivolt range, which is too small for a microcontroller to read directly. To achieve precise measurements, this sensor must be used in conjunction with a dedicated analog-to-digital converter (ADC) module, such as the HX711, which amplifies the signal and converts it into a digital format. This pairing with an Arduino or other microcontroller enables you to easily read and process the weight data. Whether you're a student, a hobbyist, or a professional, this mini force sensor provides the accuracy and reliability needed to bring your projects to life.
This 1KG Load Cell uses strain gauge technology to measure force and convert it into a small electrical signal. It is commonly used in digital weighing systems, smart kitchen scales, and automated industrial setups. With a rated capacity of 1 kilogram, it offers high sensitivity and repeatability when used with an amplifier module like HX711.
Made from high-strength aluminum alloy, the sensor is lightweight yet rugged, with 4 strain gauges bonded in a Wheatstone bridge configuration for accurate measurement. It has M3 mounting holes and four color-coded wires for easy interfacing.
