In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

The Ikea Timmerflotte temperature and humidity sensor is a complete steal for what it offers. It’s affordable, Matter-compatible and delivers reliable readings, all wrapped in a clean, unobtrusive ...

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 ...

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, ...

Steve Moser has posted on X about some code he found in the Home app of the iOS 26 beta. The code describes an “Adaptive Temperature” feature for home thermostats, which appears to offer several ...

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 ...

DESCRIOTION The Temperature Monitoring System is a useful and practical electronics project that allows users to measure and monitor ambient temperature using a digital temperature sensor with Arduino ...

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 ...

ROME—NATO is working on finalizing a stand-in jamming capability code in the coming months that could provide an impetus for more member states to introduce such systems. The code should be formally ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...
