Have you ever wondered if your house is safe while you are someplace else having the time of your life. Well, you need not to worry anymore as the burglert will take care of this for you. The Burglert is a device which lets you know if someone has entered your house without your permission. the device will send an SMS to your phone alerting you that a burglar has entered your house. It is a setup which uses Bolt WiFi Module along with an LDR which measures the intensity of light and sends an alert when the intensity lies between a specific range of limits.
The berglert cam be considered to be of 2 parts. The first is the LED which will be fixed to your door and the second part is your LDR which will be placed in such a way that the light from the LED will be falling directly on the LDR. This whole setup is placed in a box so that the LDR can detect the light coming from the LED only. If the burglar were to open the door the LED attached to the door would also move away from the LDR thus reducing the intensity of the light falling on it. When the intensity reduces the device send an SMS to your phone alerting that theres a burglar in the house.
The different components of the system are linked as shown below. The user can turn on or off the LED based on whether he is at home or not. This is done by connecting the LED to the bolt module which in turn is linked to the bolt cloud. The HTML codes are entered in the product code which enable the user to control the LED.
Putty is used in order to fetch the data from the LDR. The codes are written in python. The input from the LDR is read by the commands in the bolt python library. if these inputs fall within a range of values an SMS alert will be sent to the user via twilio SMS service letting the user know that a burglar has entered the house at so and so time.
