Rancangan Timbangan Digital Range 2 Kilogram Menggunakan Load Cell Berbasis IoT (Internet of Things) ESP 8266

Abstract

With advances in technology, devices that previously operated analogue are now being developed using digital techniques, and manual equipment is starting to turn into automatic. Digital scales are measuring instruments for measuring the mass of an object or substance with a digital display. This research aims to produce a digital scale based on the NodeMCU ESP8266, using the HX711 load cell sensor, displaying the load value on a 16x2 LCD, and displaying it in real time on the IoT website. This makes measurement results easier to read and more accurate compared to analog scales. From the test results, the tool is able to measure loads with a maximum load of 2 kg with an accuracy of 99.87%.
