Temperature Measurement for Lab and Science Projects

Introduction Every lab (home, office, school) needs temperature measurement capabilities. Measuring temperature for science experiments is hard – all sorts of materials, liquids, and chemicals may be involved or a large temperature range may need to be covered. The sensor used for this (a thermocouple) is not easy to interface, and the sensor amplifier is …
