Works well but sensitive to noise

The sensor itself is fine, but I noticed some fluctuation in readings when near other power supplies. Adding a capacitor helped stabilize it. Good for learning, but requires some tuning for professional results.

Accurate and reliable

I used the 10kg option for a coffee bean scale project. The accuracy is impressive after calibration. The plastic tray fits snugly onto the metal bracket. Highly recommend for hobbyists.

Great starter kit

Bought this for my son's science fair project. It was easy to assemble and the code samples made it simple to get weight readings on the serial monitor. Very happy with the purchase.

Perfect for Arduino projects

This kit had everything I needed to build a small digital scale. The HX711 module connected easily to my Arduino Uno, and the library examples worked right out of the box. The bracket is sturdy enough for light-duty weighing.

Solid components

The aluminum bracket is well-machined and the load cell seems durable. I tested it up to 8kg on the 10kg model and it remained linear. Just ensure you have a stable power supply for best results.

Good value but instructions could be better

The hardware quality is excellent for the price. The load cell feels precise. However, the included paper manual was very brief. I had to look up online tutorials for wiring details. Once set up, it works great.

5 FAQ

Q: Can the weighing tray be replaced if it breaks?

A: The tray is a standard size for this bracket type. While we sell the full kit, generic replacement trays of similar dimensions can often be found or 3D printed by users.

Q: Can I use the 40kg load cell for weighing heavy packages?

A: Yes, the 40kg option is designed for heavier items. Please ensure your power supply and microcontroller can handle the specific requirements of the higher capacity cell.

Q: Is there a Python library available for Raspberry Pi?

A: While we do not provide official software, there are several open-source Python libraries available on GitHub specifically for interfacing the HX711 with Raspberry Pi GPIO pins.

Q: What is the accuracy tolerance of the sensor?

A: The typical accuracy is around 0.01% of the full scale range, though this can vary slightly based on calibration quality and environmental stability.

Q: Does this kit include the necessary wires to connect to an Arduino?

A: Yes, the kit includes a set of jumper wires suitable for connecting the HX711 module to Arduino or similar microcontrollers.
