Simple Pir Motion Sensor Circuit Diagram. Pin 1 is vcc which is connected positive 5v supply. 2 pir motion sensor.
Infrared intruder alarm circuit diagram this is an infrared intruder alarm circuit that. Motion detector circuit schematic. This simple motion sensor alarm and light circuit is using a passive infrared sensor module also call pir sensor module.
Infrared intruder alarm circuit diagram this is an infrared intruder alarm circuit that.
This can be done on perfboard too. The post discuses 4 simple motion detector circuits using op amp and transistor. When pir sensor sense any human interference or ir light running 38khz. In our circuit we will connect a 470ω resistor in series with an led to the output pin of the pir sensor.
