The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Here we have used IR sensors to make an object detection circuit and a proximity sensor for path-tracking robots.

This IR proximity detector circuit gives an audible indication when any object comes in front of the infrared reflecting sensor (containing IR LED and phototransistor). The sound generated by the ...

An infrared (IR) proximity sensor, and a small solenoid is combined here to make the 6-Volt DC powered automatic soap dispenser unit. When the infrared sensor detects the close proximity of a hand, it ...

Vishay Intertechnology introduced a new series of Infrared (IR) sensor modules in five compact package types. These TSSP9xxx modules offer a long range presence and proximity sensing up to 2 m and 30 ...

Here, we propose net-structure proximity sensor (NSPS), which covers large sensing area and fulfills 1-ms response time. NSPS is an array of infrared reflective proximity sensor elements integrated by ...
