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 ...

An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

The LM358N is an operational amplifier or comparator which can be used to evaluate the voltage readings from the photosensors. It is one of the most important parts in an IR sensor circuit. The L293D ...

Melexis' FIR temperature sensor range is designed for temperature monitoring of critical components in EV powertrain ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...
