Works but sensitive to mounting

The sensor is very sensitive to how it is mounted. You need a rigid base and proper alignment to get accurate results. Once mounted correctly, it functions well.

Great introduction to load cells

If you are new to weight sensing, this is the perfect starter kit. The HX711 module handles the heavy lifting of signal amplification and noise reduction.

Perfect for DIY Scale Projects

This kit worked flawlessly with my Arduino Uno. The calibration process was straightforward using the standard library, and the readings are surprisingly stable for the price point.

Exceeded expectations

Used this to build a smart pet feeder. The resolution is high enough to detect small changes in food weight. Highly recommend for embedded systems.

Good value, minor wiring confusion

The sensor itself is accurate, but the color coding on the wires differed slightly from the diagram in the generic library. Once I tested continuity, it worked great.

Stable readings after warm-up

I noticed some drift in the first minute of operation, but after letting it warm up, the measurements were consistent. Excellent for a kitchen scale prototype.

5 FAQ

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

A: Yes, there are several open-source Python libraries available, such as 'hx711' or 'gpiozero' extensions, which can be installed via pip to interface with the module easily.

Q: What is the difference between the 5KG and 10KG versions?

A: The primary difference is the maximum weight capacity the load cell can measure accurately. The electronic module (HX711) is identical for both; you simply choose the sensor based on your project's weight requirements.

Q: Can this module work directly with a 3.3V microcontroller?

A: Yes, the HX711 module supports an operating voltage range of 2.7V to 5.5V, making it fully compatible with 3.3V logic boards like the ESP32 or Raspberry Pi.

Q: Do I need any external resistors or capacitors to make this work?

A: No, the HX711 breakout board includes all necessary internal components. You only need to connect power, ground, and two data pins to your microcontroller.

Q: How do I calibrate the sensor for accurate grams reading?

A: Calibration requires placing a known weight on the sensor and adjusting the scale factor in your code until the output matches the known weight. Most example sketches include a calibration routine.
