Abstract: A sapphire fiber high temperature sensor based on Fabry-Perot interference was studied in the paper. A sapphire wafer served as the Fabry-Perot cavity was fixed to the end face of the ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Whenever the temperature climbs, we all see social media posts of car dashboards offering blisteringly hot temperature claims, but how accurate are they? As the big question is, really, where is the ...

The IM19 is used in conjunction with the UM980 GNSS receiver to provide tilt-compensated Lat/Lon/Alt readings with 1cm accuracy up to 30° tilt angle, and 2cm accuracy up to 60°. Various bits of the ...

Over the past decades, physicists and quantum engineers introduced a wide range of systems that perform desired functions leveraging quantum mechanical effects. These include so-called quantum sensors ...

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...

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 ...

HomeKit has changed how I interact with many of the rooms in my house. While lighting and cameras tend to have the spotlight for most people as they can easily see the impact, environment monitoring ...

Temperature sensors are an important yet often overlooked part of a HomeKit setup. Even working as a passive tracking device, I want to add them to every room to understand more about what’s happening ...
