Arduino Uno controlled
This Arduino-driven fixture enables the essential characteristics of many types of temperature sensor including silicon, PTC, and NTC to be measured for comparing to the factory specs. It also helps you identify a faulty sensor, or match a pair of them.
The project was designed after suffering a malfunction in the domestic solar water heater. The approach is based on the Joule effect: a small metal plate thermally coupled to the DUT (device under test) is heated to a constant, adjustable temperature. After stabilization you can measure the sensor’s characteristics at different temperatures set with the help of your Arduino Uno.
