Homework 6 - MAE 40 - Fall 2023 8. Op-Amp Circuit for Force Sensor You are designing a circuit for an experimental setup where you have a force sensor that will experience a load between 8N and 15N. Over this range the force sensor outputs a voltage that is linearly proportional to the applied force and provides an output of 2.2V to 2.9V. You are collecting the data with an Arduino which has a 10-bit analog-to-digital (A2D) converter that measures voltages between 0V and 5V. You want to mea- sure the applied force with as high a resolution as possible. You can assume that the op-amp power supplies are +15V and -15V. (a) Calculate the resolution in Newtons (N) if you directly connected the force sensor to the Arduino A2D pin. (b) Design an op-amp circuit that will convert the 2.2V to 2.9V sensor output into a signal that ranges from 0V to 5V. You can use multiple op-amps and resistor values of your choice. Draw your circuit and show your calculations for the output voltage of the sensor when the sensor output equals (i) 2.2V and (ii) 2.9V. (c) Calculate the resolution in Newtons of the new circuit that you designed. 9. Problem 4-11 6
