Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...

Designers face many chal lenges when placing thermal-sensing components in embedded systems. The first comes in choosing the temperature sensor. It is often not obvious whether a thermistor, resistive ...

Probably the most electronically sensed analog quantity is temperature. An essential factor in most environments and critical in many, temperature is widely sensed in industrial, automotive, building ...

Almost all processes, measurements, and control systems vary as a function of temperature. Today's engineers are required to design systems to measure temperature in order to accurately control other ...

To see if a fish is fresh, people recommend looking at its eyes and gills or giving it a sniff. But a more accurate check for ...
