Tindie Weblog | Precision Load Cell Weight Scale


There are various fields the place exact weights are essential. From laboratory science experiments to cooking and baking, understanding how a lot one thing weighs may be extraordinarily essential. Getting high-precision weight measurements sometimes requires a top quality load cell and a high-performance instrumentation amplifier to measure the change in resistance throughout the cell as weight is added. The HX711 is an built-in circuit containing each a load cell front-end amplifier in addition to a good-quality ADC to digitize the outcomes. This acrylic-encased load cell comes with an HX711 breakout so you’ll be able to rapidly combine the dimensions into no matter utility you want!

The clear acrylic look matches effectively in each residence and workplace environments. Acrylic is simple to scrub in case measured gadgets get spilled onto the dimensions. With this system and a microcontroller system of your alternative, you may get exact weight measurements as much as 40kg (about 88lbs). You possibly can simply calibrate the system your self if desired to extend measurement precision utilizing normal weights and a calibration routine. Add an OLED or LCD show and some buttons, and also you’ve acquired an ideal, DIY scale system. Or, you possibly can use this scale in an automatic system, for instance, an computerized cookie machine or a bartending robotic.

For the value this is a superb purchase — there are Arduino libraries that may get you up and working in a short time, however you can too construct your personal load-cell front-end if you wish to actually get each final decimal level out of the system! This may make an ideal first microcontroller undertaking for somebody simply studying C/C++ or Micro/CircuitPython. Try the vendor’s retailer for plenty of cool breakouts and devices!
