WWZMDiB 4Pcs HX711 Load Cell Amplifier 24-Bit ADC Weighing Sensor Module Used to Measure Force, Pressure, Displacement, Strain, Torque, Acceleration.

works very good with proper Arduino uno/minima software #include "HX711.h" //_Arduino_library is what I used

I ordered 4 of these and they came promptly in individual anti static bags. All 4 of mine came configured for 80hz, much to my surprise. I haven’t plugged them in yet, but the 80hz pads have the 0Ohm resistor on them.

These were part of my entry into load cells and programming. Used this with a 200kg load cell and an ESP32S3 to make a valve spring tester. Works just fine. There is a contact on this board that increases the sample rate from 10/sec to 80/sec and should be modified to give quicker data for display.

I'm reading a 5 ton load cell. Looking to record a force curve for a 100 ms impact, so I needed the promised 80 hz sample rate. (Wanted more, but this is "good enough") The undocumented change required removing a soldered 0 ohm resistor (a short) from one location to another on the breakout board. ... Tiny ... Have a sharp soldering iron and some skill. 5 stars for value. Even with the challenge. The

Used two Load Cells to demonstrate the effect of torque multiplication for a 5th semester mechatronic intern project. She designed, build, and programmed this, including making the gears on Creality 3D Printer.

I am not seeing 3.3V on The E+<->E- pins on the load cell side. My Voltage Readings are: Vcc<->Gnd=3.3V Vcc<->E+ =3.3V (Red on Vcc, Black on E+/-) Vcc<->E- =3.3V (Red on Vcc, Black on E+/- E+<->E- =0.0V GND<->E+ =0.0V GND<->E- =0.0V. The specs indicate the board should be able to run on 3.3v This is the second board - same results. Any Suggestions

Items work as advertised.

using these to convert other loadcell devices, to this chip, to use for nodemcu projects.
