PIR Motion Sensor Tutorial : 8 Steps (with Pictures ...

PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors input and begin explaining how a basic sensor works, we'll use the rather nice diagram below (if anyone knows where it originates plz let me know).

PIR Sensor input/output voltages - Sensors - Arduino Forum

· I have some of these PIR sensors [image] Specs say input voltage of 5v-12v, so there's some kind of onboard regulator, possibly 3v3. So the output signal is 3v3 regardless of input voltage? Is there any point in giving this sensor more than 5v? Does the excess just give the regulator more to do with no gain in sensitivity/ sensing range?

· Schaltplan Hauptteil dieser Schaltung sind Timer IC555 und PIR (passiver Infrarot) Sensor. Diese Schaltung empfängt Trigger-Eingang vom PIR-Sensor und aktiviert Relais durch Timer-IC-Ausgang. PIR-Sensorausgang wird direkt in die Basis des Transistors BC547 eingespeist, und dann wird der Kollektoranschluss mit dem Schwellenwert und dem Triggerstift des IC555 über einen …
