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.
Supplies
Pir sensor x1
18650 battery x1
battery charger module x1
buzzer x1
toggle switch x1
wires x1
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.
