The built-in web server, which is hosted on the ESP32, allows monitoring through any device connected to the local network, ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure shows an infrared ...

France-based infrared sensor maker Lynred has officially kicked off a new European project to develop high-performance devices for use in future defense systems. The Grenoble company is coordinating ...

This burglar alarm system circuit is using a infrared proximity detector that triggers an alarm when the rays falling on its sensor are interrupted. It is different from others burglar alarm systems ...
