Arduino has become one of the key building blocks of the open hardware movement. Arduino, the platform, is designed to be modular, affordable, and easy for virtually anyone to use. The company behind ...

Tired of building the same old Arduino projects like blinking LEDs, temperature monitors, and line-following robots? Now it’s time for something fun. It’s time to turn your skills into entertainment ...

* Accuracy for full range. More exact details for smaller ranges, see datasheet (page 8). One of the interesting functions is the support of an ALERT function. This prevents the need for continuous ...

Sonoff has announced the launch of two affordable smart air quality sensors. The AirGuard PM2.5/PM10 model monitors fine particles, temperature and humidity, whilst the CO₂ version adds carbon dioxide ...

Abstract: While conventional optical fiber humidity sensors offer high sensitivity and stability, their size limits their application in narrow spaces. To overcome the limitation, this paper presents ...

Researchers developed a fingertip-sized, humidity-tolerant hydrogen sensor using platinum nanoparticles that catalyze reactions, thin a water film, change color, and trigger alarms. (Nanowerk News) ...

The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine coolant temperature (ECT) sensor (below). In practical terms, the ECM believes ...

Imagine walking into a room that automatically adjusts its temperature and humidity to your comfort level, no apps, no manual adjustments, just seamless automation. Sounds futuristic? Not anymore.

Paul and David Bradt’s Ardiono Projects offers multiple ways to use Arduino and Raspberry Pi microcontrollers for your model railroading projects. Buy the book here. Code for Button/Blink Test (SN095) ...

We love Arduino here at Hackaday; they’ve probably done more to make embedded programming accessible to more people than anything else in the history of the field. One thing the Arduino ecosystem is ...
