This sensor has three output pins Vcc, Output and Ground as shown in the pin diagram … The main electronic component we will use that allows us to pick up this detection is the PIR motion sensor. This sensor module has been designed as an alternative to the common PIR motion sensors widely used in burglar alarms and security lights. Add Tip Ask Question Comment Download. If you only have buzzers that need more voltage, then you'll have to power the buzzer with an external power source. PIR Sensor is one of the most commonly used sensors for motion detection. They are used to detect whether a human has moved in or out of the sensor’s range. When the PIR Sensor detects any human body movement, its OUTPUT pin becomes HIGH (Vcc) and when it does not detect any human body movement, its OUTPUT pin becomes LOW (Ground).Here the BC547 Transistor work as a switch. Motion detector circuit can be implemented by using different controllers like 555 timers, microcontrollers, etc., and by using different sensors like IR, PIR, and the Ultrasonic sensors discussed above. They are commonly found in appliances and gadgets used at home or for businesses. Experiment to see the effect on the circuit's behavior.
