I am new here so I hope I'm posting it at the correct place.
I am having some troubles with some of my force sensors. My case is like this: I have a body which have a weight. However, the surface is not even. I wanted to measure the weight of the whole body, but with a small sensor (circular force sensing resistors with diameter of 2 cm). Hence, I know that the reading that I am getting on that specific region of my sensors are then as pressure (am I correct on this??)
I tried to make a figure out of it to help to ease things out (hopefully). So, imagine the 2 orange circles are the 2 cm diameter circular FSR sensors. The blocks over it is the weight, but it is not evenly distributed. Hence the front side have a heavier weight compared to the back side.
If so, is it possible for me to add up the "weights" that I got from the two sensors (shown as the orange circles), and then calculate the pressure by:
Pressure = (Weight1 + Weight 2)/total Area of 2 sensors
By this sense, can I assume that I am able to get the total weight, by using this formula:
Total Weight= Pressure (from eq. on top) * Total area of the "grey" box
Any help would be really great!
Thank you in advance for your help!
