SMTAS04USB mini – Evaluation board for SMT172 Introduction
This document describes a 4 channel temperature measurement system: The New Smart Temperature Acquisition System (SMTAS04usbmini). It is based on the use of the Smartec temperature sensors SMT172. The SMT172 is a three terminal integrated temperature sensor with a duty cycle output. Two terminals are used for the power supply of and the third terminal carries the output signal. The output signal of the sensor is a duty-cycle-modulated square-wave signal (see Figure 1).
