Comidox 3PCS BF120-3AA 120Ω 120ohm High-Precision Resistance Strain Gauge Foil Strain Gauge for The Pressure Sensor Load Cell

today we are going to take a look at the strain gauge and how they work how to properly read their output and use them in everyday project as its name implies these devices are used to measure strain or deformation over an object if we know the gauge factor of this device just by measuring the strain we can easily pass the deformation measure to force measure over that object then the measured force will be translated into weight so basically using a strain gauge we can go and measure weight this can be very useful with our project that require precision weight measurements we can build a scale for example a feather device by weight the tech when somebody plays something over surface and much more so in today's video you will understand how a common strain gauge works then we will see how to pass from resistance values to voltage values and read that with an ADC and then measure the def
