The PIR sensor used in the circuit will detect human IR radiations, when the sensor detects the human radiations its output goes high and activates the UM3561 IC. The UM3561 is a four siren sound generator IC and in this circuit we are only using one of its siren. At the output of the UM3561 IC a BD140 transistor is used to amplify the output ...

The PIR motion sensor is a sensor which detects movement through picking up infrared waves. Being that a person emits infrared waves, the detector is able to detect these waves and react, according to the how the circuit is designed to react. The sensor can also pick up the movement of inanimate objects as well, such a rolling ball, because as those objects move, friction acts on them ...

HC-SR501 PIR sensor has three output pins VCC, Output and Ground as shown in the diagram below. It has a built-in voltage regulator so it can be powered by any DC voltage from to 12 volts, typically 5V is used. Other than this, there are a couple options you have with your PIR. Let’s check them out.

· See the circuit diagram below. When a signal from an Infrared PIR Sensor module comes to the circuit. It is a 3V peak voltage. Then, this voltage flows to the base of Q1 through R1-current limiting for the transistor. Now Q1 runs, the current can flow from the 12V to a relay coil. The RY1 pulls contact C to NC. Next, the siren alert with a lot louder. At the same time, LED glows up. Because ...
