Smartec sensors and the Smartec UTI can be applied in many different ways to create ingenious devices. Our experience is that writing software measuring times and duty cycles (which is what you have to do to use our temperature sensors or the UTI interface) is not so easy. This is especially true when you are using low cost low speed microcontrollers. To support the designer in achieving his goal Smartec created ready to go software software, as well as examples of how to write software yourself and how to overcome all kinds of problems like synchronisation and resolution errors. As the UTI is really a Universal Transducer Interface it will not surprise you to find examples of quite different applications, such as measuring low voltages (thermocouples) and how to connect 6 Pt100 elements (four wire) to the UTI or connect such elements with cables up to several hundreds of meters long
