FresnelLinsen werden nach wie vor eingesetzt, wenn das Gewicht der Linsen ausschlaggebend und die Abbildungsqualität zweitrangig ist. Bei Richtfeuern wird nur eine Linse verwendet, während bei Drehfeuern mehrere Linsen im Kreis drehbar um die Lichtquelle angeordnet sind.. Hinter Rückprojektionsbildschirmen befand sich eine FresnelLinse, um die Ausleuchtung der Mattscheibe …

PIR Sensor Circuit and Working with Applications

+

PIR sensor consists of three pins, ground, signal, and power at the side or bottom. Generally, the PIR sensor power is up to 5V, but, the large size PIR modules operate a relay instead of direct output. It is very simple and easy to interface the sensor with a microcontroller. The output of the PIR is (usually digital output) either low or high.
