We don’t know if this will come as a surprise to the regular Hackaday reader, but a whole bunch of Atmel microcontrollers have a very cool feature hidden away in their datasheets. Most of them – ...

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

Nowadays, numerous electronic sensor modules are available on the market that can be combined with inexpensive microcontroller boards to measure environmental parameters of importance. The project ...

This project is to prototype a set of self-powered (such as piezoelectric, thermostat, solar, etc) embedded sensor systems for pervasive computing. A tangible exam is a body-temperature powered motion ...

Whether you are building a temperature-sensing device or need to bring temperature-sensing capabilities to an existing system, you should familiarize yourself with thermocouples and learn how to ...

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...
