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 – ...

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 ...

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 ...

The semiconductor chips driving modern-day computer processors are covered in billions of individual transistors, each of ...

Local-first wins.

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 ...

We may receive a commission on purchases made from links. Though the meaning of smart home varies depending on who you ask, with so many useful smart sensors for your home, if your home isn't smart, ...

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 ...

Environmental temperature fluctuations can cause sensor output variations separate from measured pressure. A sensor’s thermal sensitivity dictates the severity of these output errors, with higher ...
