Reliable and Compact
I've used several of these modules for a custom coffee scale. The small footprint makes it easy to fit into tight enclosures, and the noise rejection is impressive.

Works well with Raspberry Pi
Integrated this into a smart pet feeder system. It communicates reliably with the GPIO pins. Only giving 4 stars because the soldering points are a bit small for beginners.

Perfect for DIY Scale Projects
This HX711 module works flawlessly with my Arduino Uno. The setup was straightforward using the standard library, and the readings are stable and accurate for my 5kg load cell project.

Good value but needs calibration
The hardware quality is solid for the price. Just remember that you must calibrate it properly with known weights to get accurate results. Once calibrated, it holds the value well.

Consistent performance
Using the 10kg version for a small inventory scale. The drift is minimal over time, and the refresh rate option helps when I need faster updates. Excellent product.
Q: Does this module come with the load cell included?
A: No, this listing is for the HX711 amplifier module only. You need to purchase the compatible load cell (1kg, 5kg, or 10kg) separately based on your weight requirements.
Q: How do I switch between 10Hz and 80Hz sampling rates?
A: The sampling rate is controlled by the number of clock pulses sent after reading the data pin. Sending 25-27 pulses selects 10Hz, while 28-31 pulses select 80Hz. This is handled automatically by most standard libraries via configuration settings.
Q: What is the maximum wire length recommended between the load cell and the module?
A: For best signal integrity and noise reduction, we recommend keeping the wire length between the load cell and the HX711 module under 1 meter. If longer distances are needed, shielded cables are advised.
Q: Is there a library available for Python?
A: Yes, there are several open-source Python libraries available for Raspberry Pi and generic GPIO usage. You can find them on GitHub by searching for 'HX711 Python library'.
Q: Can I use this with a 3.3V microcontroller like the ESP32?
A: Yes, the module operates within a voltage range of 2.6V to 5.5V, making it fully compatible with 3.3V logic systems like the ESP32 and Raspberry Pi without needing level shifters.
