for an upcoming project, I will want to monitor the temperature of several devices concurrently, imported to my PC. My initial thought was to attach thermocouples to all of them, fed into a thermocouple data acquisition unit, but I have not been able to find such a data acquisition unit for any reasonable price (all I found were 400$ or above). As this is for my own home tinkering, cost is a huge factor. I did find this DAQ unit for 59$ which has (8) ±10V inputs. I was thinking as a cost saving measure to scrap the thermocouples, and use RTDs with a fixed resistor as a voltage divider to generate an analog voltage input into this DAQ. But I have no idea how reliable (repeatable) this would be. Also I beleive this would give me a nonlinear analog signal for a linear increase/decrease in temperature which I'm not sure can be scaled properly in the software. Any input?
