2 Sets 50kg Load Cell E-Shaped Weighing Sensor Strain Half-Bridge Sensor + HX711 A/D Amplifier Weight Module DIY Kit (50KG, HX711)

Used in a project either an esp32s3 and they interfaced easily and work well. Driven with the 3.3v Vcc.

I bought these in anticipation of using them for a project, to which I am now getting. I need to build my platform, but have been working with the HX711 boards and a Python library that I found on line. Since I have not formally mounted these, I cannot speak a great deal to their accuracy, but a note of caution - if you find a library online and there are comments - read ALL of the comments, I discovered the article had errors and the author has done nothing to correct them. Use the wiring scheme presented here on Amazon. Use one cell per HX711 since channel B does not have the same options as channel A. I found the HX711 works with 3.3 volts (RPi) as well as 5 volts (also RPi, but the GPIO's are rated at 3.3 volts and will burn out at 5 volts, but I tried 5 volts and my RPi is working, but went to 3.3 volts) The HX711 mounting holes are around 2.6mm, definitely less than 3 mm (M3), Amazon has screw kits for M2.x screws, watch for the flat head v pan/hex/etc - the flat head could split your board if you get it too tight.

Made a scale with one of these and a raspberry pi, pretty accurate.

I received this item as a Christmas gift. Unfortunately I just got around to playing with them this weekend and one of the load cells was defective right out of the package. It had a broken or unconnected wire. I recommend that you check the resistance between all wires right away so that you can return them if defective. The resistances should read: Green-White = 1kOhm Red-Black = 1kOhm All other combinations = 0.75 kOhm

Purchased the 10 kg versions. Load cells and HX711 were used with an ESP32 at 3.3V with no issues, and typical accuracy and precision expected. However, took off a star because of misleading information on threaded mounting holes. The design drawing specified two M4 and two M5 threaded holes. All the holes on the 10 kg cells were M4-0.70 threads.

Rate is NOT selectable as stated in the description. It only samples at 10SPS and there is no way to change it to 80SPS. Seller sent me to a GitHub page as an answer to this question but there is no info on rate in the github link.

Works well and is pretty accurate across the range. Easy to setup and use with Arduino.

This can only read at 10Hz, other boards such as the SparkFun break out board has an option to cut a trace to make it read at 80Hz, but this board is fixed.
