This is a project circuit which helps to a person in the driving seat and gives an alarm if there is any obstacle or a wall while parking or while driving in reverse. This is a project circuit which ...

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 ...

Ever wonder how to calculate revolutions per minute using a microcontroller? This project shows you how by purposing an IR emitter and detector and a computer fan. As the fan blades spin they disrupt ...

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 ...

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 ...
