ESP, easy as ABC.

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 ...

First of all, there are definitely simpler ways to monitor remote temperatures, but [Mike]’s remote MQTT temperature sensor and display project is useful in a few ways. Not only does it lay out how to ...

This tiny, inexpensive microcontroller makes it easy to build reliable, room-by-room Home Assistant sensors without paying the smart home tax.

NewTek manufactures custom linear position sensing units in various strokes, sizes and materials, engineered to operate ...

Walking through most process plants or remote facilities, an observer will encounter a sizeable collection of temperature and pressure instruments. Without knowledge of the two critical parameters of ...

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 ...
