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 – ...

Tired of condensation wrecking your shed tools or greenhouse gear? I built a no-frills ESP32 + DHT22 node that wakes every 15 minutes, grabs temp/humidity data, beams it over Wi-Fi, and sleeps—running ...

When they need to add temperature control to a project, many hackers reach for a K-type thermocouple for their high-temperature needs, or an integrated temperature-sensing IC when it doesn’t get that ...

Sensor plays very important role in robotics and plant automation. One of the important areas in Industrial applications is Interfacing their output to the firmware. It is very important to understand ...

Thermopile sensors offer a reliable way to measure temperature without physical contact, making them ideal for real-world applications where speed, safety, and precision matter. Whether you are ...

Local-first wins.

In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...
