Arduino Bathroom Scale With 50 Kg Load Cells and HX711 Amplifier: This Instructable describes how to make a weighing scale using readily available off the shelf parts. Materials needed: Arduino - (this design uses a standard Arduino Uno, other Arduino versions or clones should work also) HX711 on breakout b. You can buy relatively cheap bathroom scale load cells from China.
Each cell is rated for 50 kg / 110 lbs. They can safely handle 120% overload (60 kg / 130 lbs per cell) and the ultimate overload of 150% (75 kg / 165 lbs per cell). Going over the maximum limit can permanently damage the load cells.
I forgot to mention some critical details about mounting the 50kg bathroom scale load cells to a wooden board. It is important that the strain gauge has room to move up and down. This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year's resolutions, and then forget about a month later).
This sensor can measure up to about 110 pounds. Check the video below for a simple explanation on how these work and how to use them. One end of the sensor through the screw holes fixed and the other end to keep floating.
Applied according to label directions direction of gravity. This item is used widely in hopper scales, platform scales, platform balance, belt scales and other electronic weighing devices.

Whether you're a consumer replacing faulty cells or an OEM manufacturer designing smart bathroom scales, choosing the right load cell ensures long-term reliability, precision, and user trust. These load cells are listed as "half-bridges." However in fact they only have 1 strain gauge in them, but they have a passive resistor that can be wired as a dummy leg of a Wheatstone bridge, so that one, two, or four of these load cells can be configured in a full. Types of Bathroom Scale Load Cells A load cell is the core sensing component in a digital bathroom scale, responsible for converting applied weight into an electrical signal that can be processed and displayed.
The accuracy, durability, and responsiveness of a scale largely depend on the type of load cell it uses. Below is a comprehensive overview of the most common types of load cells used in. Connect the load-cells to an HX711 amp according to instructions available all over the internet, and that's about it.
As I had touch buttons on the face of the scales I used those to bring the ESP out of deep sleep.
