Story

I want some that guard my room when I'm not there that's why I made this it has a pit sensor that sens motion and sends a notification on my phone this is the first version in the next version I'm trying to add a camera and sends me image or video.

library:

WEBSERVER(creation):

so we need to write some Html code for our page if you are new to Html or not good at you can also visit this

IFTTT:

so I am using ifttt's webhook service to send me a notification on my phone for this you need to have ifttt app in your cell

firstly need an account in ifttt

Click on create

.click on THIS

.click on THIS

search webhooks and click on it

Click on Receive a web request

give event name as you want and also click on CREATE TRIGGER

Click on THAT

search notification and click on it

click on send a notification from the IFTTT app

write your message and if want you can also add occurred at that means the time of occurrence

after this click on create action

then click on finish

then click on home and go the home page

now click on the webhooks

now click on the documentation

now type event in that box for ex: I write there lock_s my event name

now copy the key and paste on your code and also by clicking on TEST IT you can test it and able to see the notification in your phone

paste the key there.

you will get this type of notification in your cell.

Connection:

connect pir to D1 or GPIO 5 of NodeMCU
connect the buzzer to D2 or GPIO 4 of NodeMCU

this will help you.

WEBSERVER:

you need to put your board's IP on the browser to set and control the system.

in case you don't know the IP of your board

Serial.print(WiFi.localIP());

you need to paste these lines on the setup of your code and don't forget to begin serial.
so set a pass there to activities the system or deactivate the system.

this is an activation pass you can also put as per your choice.

this is deactivation pass you can change as per your choice.

after giving pass click on the button to execute.
