Now do the experiment, build your own test platform and buy 4 pressure sensors, I am responsible for how to collect the experimental data But I don't understand very well, all ask everybody.Signal amplifier, analog signal conversion, how to connect to the computerPS: what kind of software acquisition is used in the general data collection?
The pressure sensor is voltage type (0-5V, 1-5V) or current (4-20mA), connected to the DC power supply and load resistance, received together and a sensor, as long as the acquisition of current and voltage in the circuit, then you can calculate the value of linear pressure
You'd better add a module in the middle...Data acquisition, communication, host computer
Having a dedicated digital to analog converter
