Introduction: Home Security Motion Sensor
In this instructable ,I am going to build you can build a PIR motion sensor home security system.you can make your own casing and layout.
Pir sensor x1
18650 battery x1
battery charger module x1
toggle switch x1
Step 1: The Wiring
Connect the battery's + and - to the chargers + and -.Take a wire from the + and connect it to the middle pin of the switch. Take a wire from any side of the switch to the vcc of the pir sensor. Connect the battery's - terminal to the GND of the PIR sensor.Connect the out of the sensor to the input of the buzzer and the battery - terminal to the GND of the buzzer.
There is a jumper n the circuit side that can be used to set different output modes but the motion sensing will be the same. Also we can solder a temperature sensor or an LDR, then the PIR sensor will only work at night.
