This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to 20mA ...

Here is an Ultrasensitive Heat Sensor to monitor high temperature in Electronic devices. It can be placed inside the electronic gadget that usually generates heat during its operation. The circuit ...

A team of researchers at Northeastern University have developed a new sensor powered by the very infrared energy it’s designed to detect. The device, which was commissioned as part of DARPA’s Near ...

A wireless sensor node by Germany-based Micropelt is powered by harvesting thermoelectric energy. When a product derives its power from batteries, the user is saddled with the inconvenience of ...
