# 6301-lab3
Temperature sensor carrier board with PTAT cell, dual-slope ADC, and Arduino Nano.
The PTAT cell features breakaway design of the temperature sense area for remote measurement.
Temperature sensor carrier board with PTAT cell, dual-slope ADC, and Arduino Nano. The PTAT cell features breakaway design of the temperature sense area for remote measurement. Final error after calibration was less than 5%.

Circuit and layout drawn in Altium 17.0.

### Conversion Results

Linearity is very good. There is a constant offset error, which can be removed through calibration.
