The sensor is a ‘standalone’ infrared proximity sensor, so no external control/driver circuitry is needed to play with it. You can directly connect a low-current 5V electromagnetic relay or ...

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 ...

Download this article in PDF format. 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 ...

The video demonstrates how to wire up a Passive Infrared Sensor (PIR) using 4-core security cables. All Gallagher inputs are balanced 4-state inputs and must have two 4k7 resistors wired at the device ...
