What is a loadcell? How can it be used in your project? Introduction The force transducer measures a stress applied by the user or an object and transmits it to the arduino board in the form of a voltage. It consists of a force cell. The force cell is a strain gauge used to measure force. The force transducer measures a stress applied by the user or an object and transmits it to the arduino board in the form of a voltage. It consists of a force cell. The force cell is a strain gauge used to measure force. The force sensor can read a value ranging from 0 newtons to 10 newtons, which corresponds to 1kg. You can find sensors up to 2-3 kg on arduino.Depending on what you need for your project, there are force transducers of different sizes and precision.Some sensors also have a conversion module to amplify the signal and convert it into a digital value. These sensors are plugged into a digital terminal on the Arduino board.Here is a kit of different pressure sensors using a conversion module: The force sensor pins Vcc: Must be connected to the 5v of your Arduino boardGND & Signal: This pin is connected to a 9.1 kilo-ohm resistor, an analogue terminal and earth. Display value on serial monitor We’ll now see how to display the force values on the serial monitor in Newton-metres: Measuring force with LEDs We’re now going to look at how to light up LEDs as a function of force in Newton-metres.
