Manufacture of Electronic Weighing Machine Using Load Cell

We have seen weighing machine at many shops, where machine displays the weight just by placing any item on the WEIGHING platform. The building of the weighing machine can be done by 7 segment LCD display using required DRIVER ICs, MICROCONTROLLER or by USING ARDUINO. Our project is to design weighing machine using ARDUINO & LOAD CELL, having capacity of measuring up to 20kgs. This limit can be further increased by using the load cell of higher capacity. In our project we have used HX711 IC& ARDUINO 1 . Here load cell acts as a transducer which transforms weight into Electrical Output. The basic unit of Load Cell is Strain Gauge which deforms when pressure is applied on it. Load cells are highly accurate transducers which provide the user with the information not generally obtainable by other technology due to commercial factors 2 Implementing arduino in weight measurement machine is easy and also economical. Initially one needs to calibrate this system for measuring the correct weight and after that the operation gives pretty accurate results. -------------------------------------------------------------------------------------------------------------------------------------Date of Submission: 28-07-2019 Date of acceptance: 13-08-2019 -------------------------------------------------------------------------------------------------------------------------------------
