This Design Idea implements a remote sensor preamp (e.g., for a piezoelectric transducer) which transfers both signal and power over a single wire pair or coax. R6 provides a matching load to the ...

Smart homes of the future will automatically adapt to their surroundings using an array of sensors to record everything from the building’s temperature and humidity to the light level and air quality.

Conventional thermostats are based on separate temperature sensor and heater devices with means for feedback between them. But in some recent EDN design ideas (DIs) we’ve seen thermostat designs that ...

This file type includes high resolution graphics and schematics. Force sensors weigh freight on manufacturing and transportation equipment. They also monitor loads on machines subject to stringent ...

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 ...
