Accurate signal conditioning and high-resolution measurements are no longer limited to industrial or instrumentation applications. Designers of portable consumer- electronic equipment also need to ...

The approximately –2-mV/°C temperature coefficient of diode junctions is a popular means of temperature measurement, especially in cryogenic applications (Figure 1). Diode temperature sensors are ...

The importance of understanding and using wiring diagrams to troubleshoot refrigeration systems cannot be overemphasized. Most system problems can be divided into two broad categories: electrical or ...

Sensors are increasingly important in mobile devices. Combining data from cameras, microphones, inertial sensors, beacons (e.g., GPS) and proximity-based sensors can greatly improve the accuracy and ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

Researchers have developed a sensor array design technology inspired by the human auditory system. By mimicking the human ear's ability to distinguish sounds through tonotopy, this innovative sensor ...

Non-contact proximity sensors can improve the ruggedness of manufacturing operations, such as metal component assembly, by replacing delicate mechanical switches. Sensor selection for these ...
