Real-time environmental monitoring is increasingly important in agriculture, industrial automation, smart homes, and healthcare. The real-time data monitoring ...

Flexible, low-cost temperature- and pressure-sensing devices are of profound importance in satisfying the urgent requirements for many advanced artificial ...

The main principle of this circuit is to display the digital temperature value. Here, ATmega8 microcontroller is used. The ATmega8 has inbuilt analog to digital converter with six multiplexed channels ...

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 ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

For third-gen Nest and Nest E owners, sensors make a great upgrade to an already very good thermostat. It was a long time coming, but Nest has finally released its remote temperature sensor, which ...
