Pir Sensor & Camera Room Security Email Alerts

Made by electrouser245 / Security / Sensors

About the project

Using a PIR sensor with a camera for the raspberry pi, you can create a room security system. The PIR sensor can detect motion and will then activate the camera to take a snapchat photo. The python code will then email the snapshot as an attachment to your own email address.

Story

Using a PIR motion sensor with a usb webcam or a picamera for the raspberry pi, you too can turn your raspberry pi device in a home security system which will send email alerts when someone enters your room.

The PIR sensor will detect motion, example someone enters or walks up to your desk. This is then activate the webcam or picamera and take a snapshot of who entered.

The image will then be sent as an attachment to your own email address.

So image your out and your annoying younger brother or sister tries to steal something from for room This device will then modify with a snapshot and time-stamp which can be received on your phone, proving they entered and the times when they did.
