I have to make monitoring system of real time pressure and temperature sensor data. how i can do it with matlab and what are the other hardware components i need?

I need to monitor graph plot of sensor data in real time. I am not sure what are the other hardwares i need to display the data in matlab

[Walter Roberson]

What kind of hardware interfaces does your sensor have?

Do you have information about how the hardware measurements for the device correspond to readings? For example does a change of 1 in reading of the temperature sensor correspond to 0.1 degree celcius, or 0.1 degree fahrenheit, or the representation N/255 of the way through the range between some minimum temperature and maximum temperature whose bounds you control by control information you write to the device?

What sensing rate do you need? How many bits wide are the samples?

What latency is acceptable in the drawing?

Is it necessary to process each sample individually as soon as possible, or would it be acceptable to read them in batches and update for the batch (for example, reading 1 second of data at a time, processing it, updating the graph) ?

Thanks for the reply, But i do not need very accurate measurement of the readings. I am going to get sensor data stored in the memory and i have to plot it in matlab. The data will be of a complete injection molding cycle. later the arrangement should be capable enough to perform when it get connected to real sensor systems by some port in the laptop to give plotting of the readings. and it should be as fast as we can.
