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 ...

Temperature sensors are an important yet often overlooked part of a HomeKit setup. Even working as a passive tracking device, I want to add them to every room to understand more about what’s happening ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Engineering students at Johns Hopkins have a noninvasive sensor under development that can quickly and accurately measure core body temperature (CBT). The team developed its sensor to help medics ...

Virtually every modern car on the road is equipped with bells, whistles, and sensors designed to let you know when even the slightest thing is wrong with your vehicle. While any driver can appreciate ...
