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

This infrared detector circuit uses a passive IR-detector component PID20. It converts heat radiation into electrical impulses. The output voltage of the PID20 increases when an object comes close to ...

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 ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

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 ...

ROHM has developed an innovative Schottky barrier diode (SBD) that overcomes the traditional forward voltage (V F )/reverse ...

Infra-red (IR) remotes are great, unless you’re in a hackerspace that’s full of crazy blinking lights and random IR emissions of all kinds. Then, they’re just unreliable. Some smart folks at Metalab ...
