All sensors are analog in nature, even an on/off switch, but how they work and how to get accurate information with the desired precision can be a challenge. The internet of things brought sensors to ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

An example is the sensing of a rotary cam position. The oblong shape of the cam dictates use of a sensor able to detect different shapes and sizes. A simple prox sensor merely detects the presence or ...

IEEE P1451.4 defines a sensor with embedded TEDS and a mixed-mode, analog and digital interface. Most sensors put out some sort of analog signal -- a voltage, current, or resistance, that varies in a ...

What’s the big deal about running an analog-to-digital converter (ADC) device? Tie a sensor output to an ADC input and start taking readings. Right? After all, digital signaling offers strong noise ...

Electronic instrumentation called data acquisition systems (DAQs or DASs) acquire data from sensors. They are often extended to be instrumentation and control systems. This is a tutorial presentation ...
