Excellent sensitivity

Connected this to a 5kg load cell and the precision is impressive. It can detect weight changes as small as a single gram without drifting too much over time.

Good value, small footprint

Compact size fits easily into tight enclosures. Signal noise is low when properly grounded. Only giving 4 stars because the pin headers were not included, had to solder my own.

Perfect for DIY Scale Projects

This module works flawlessly with my Arduino Uno. The 24-bit resolution provides very stable readings for my kitchen scale project. Setup was straightforward using existing libraries.

Reliable and Precise

We used ten of these for a student robotics competition. All units performed consistently. The ability to switch between 10Hz and 80Hz sampling rates is a nice feature for filtering noise.

Works as advertised

Standard HX711 performance. Documentation online is plentiful which helps beginners. Make sure you use a stable power supply to get the best accuracy.

5 FAQ

Q: What is the maximum length for the wires connecting the load cell to the module?

A: For optimal signal integrity and noise reduction, we recommend keeping the load cell wires under 1 meter. If longer distances are required, shielded cables are strongly advised.

Q: Does this module come with a load cell included?

A: No, this listing is for the HX711 amplifier module only. You will need to purchase a compatible load cell separately based on your weight capacity requirements.

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 such as the ESP32 and Raspberry Pi.

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

A: Yes, there are several open-source Python libraries available for the Raspberry Pi GPIO, such as 'hx711' or 'pi-hx711', which can be installed via pip to simplify integration.

Q: How do I switch between 10Hz and 80Hz sampling rates?

A: The sampling rate is selected by the number of clock pulses sent after a data read. 25 pulses select Channel A at 10Hz, 26 pulses select Channel B at 10Hz, and 27 pulses select Channel A at 80Hz. Most libraries handle this automatically via configuration.
