Unlock Precision Weighing for Your DIY Projects
Whether you are building a smart coffee scale, an automated pet feeder, or a custom industrial testing rig, accurate weight measurement is critical. The 5kg Load Cell combined with the HX711 AD Module provides a complete, easy-to-integrate solution for capturing precise force and weight data.
How the HX711 Module Enhances Performance
Raw load cells output very tiny analog signals that standard microcontrollers cannot read accurately. The included HX711 24-bit Analog-to-Digital (AD) converter module bridges this gap. It features a built-in low-noise amplifier that actively filters out environmental and electromagnetic interference. This ensures the weight data transmitted to your system is stable, highly accurate, and free from frustrating fluctuations.
Designed for Seamless Integration
Space on a breadboard or inside a custom 3D-printed enclosure is always at a premium. Both the aluminum alloy load cell and the HX711 module feature a compact footprint, allowing you to embed them into tight spaces. The four-wire interface is incredibly straightforward, operating on a standard 5-10V driving voltage, drastically reducing your prototyping time.
Built for Reliability
Constructed from durable aluminum alloy, the weighing pressure sensor is built to last through rigorous testing and daily operation. Simply secure one end using the pre-drilled screw holes, suspend the other end, and apply weight in the direction of the label to start gathering high-speed, reliable data.

FAQ Section
FAQ Section
Q: How do I wire this load cell to the HX711 module?
A: The wiring is color-coded for simplicity. Connect Red to E+ (Power +), Black to E- (Power -), Green to A- (Signal +), and White to A+ (Signal -) on the HX711 board.
Q: Can I use this with an Arduino or Raspberry Pi?
A: Yes! This kit is highly popular in the maker community. There are numerous open-source libraries available for Arduino, Raspberry Pi, and other common microcontrollers, making integration fast and easy.
Q: Why is there a warning about the white rubberized part?
A: The white rubber protects the delicate strain gauges attached to the aluminum block. Pressing on it directly can permanently deform or break the microscopic wires, ruining the sensor's accuracy. Always apply force only to the solid metal ends.
