Safety-for-life

We're surprinsingly to present our project. This project is about to use micro-controller act as sercurity system :) Secure your house and will let you know every activities at the door! (i mean notification).

So if you have a door you need a key.....it's not anymore this sercurity system let you know that

  • The key. ----------> Unnecessary
  • RFID Card. ----------> Unnecessary
  • Fills the password every time. ----------> Unnecessary

Just need the smartphone can connect to WIFI. Only 2 Step!

  • Connect WiFi to NodeMCU.
  • Door Unlocked!

How incredible!

Overview

How to use

  • When you want to get in. if you turn on wifi, your phone will connect to system automatically then you walk in front of the door if you phone don't regconize the password, fill the password.

This system have 2 mode (it's reported you on the LCD Screen Always).

  • FULL ACTIVATED MODE
    • it's appear when you outside
    • The Infrared will turn on and will detect abnormal activities. and report to you.
  • SEMI ACTIVATED MODE
    • Appear When you inside your place.
    • Infrared turn off.
    • You can use keypad function
      • Press "****" to show corrent password.
      • Press "000#" to going out.
      • Press "*#*#" to change password.
      • Press "####" open the door temporary (8 seconds).

How Secure?

  • Password Protection 8 PIN.
  • Immediately report to you when have connection to system.
  • Can check the time on Line Application when you went out or you get in.
  • Don't use physical method to get in (like key or RFID card), So in case of you forget the key. you don't need to concern.
  • Detect and report you when have an abnormal activity at the door.
  • We don't use Bluetooth because it's unsafe than WiFi system and you need to pairing.

Function

Various situations are there, so you need to know.

  • Every activities will notice you politely on the 'Line Application'.
  • if door locked and you need to enter you place.(Sign in)
    • Connect wifi ssid "I LOVE COMPRO" Fill password ('88888888' is default).
    • When password is correct. you have 45 seconds to stand in front of the door and twist door knob.
    • While you twist the door knob. Sensor will detect your activity then unlock the door. Sensor will turn off automatically.
  • if door locked and you want to go outside.(Sign out)
    • Press "000#" on the keypad. Display Show "----Door Unlocked----" Then you have 6 Seconds to open the door
      before the alart sound start.
    • After you open the door, you have 20 Sec. for going out. Sensor IR will turn on automatically.
  • if door locked and you was outside your place.
    • If IR sensor detect someone who doing unknown activities on your knob. will report line message to you.
      and alert sound will play repeating loudly.
  • if door lock and you need to open temporary.
    • Press "####" on the keypad. you have 8 seconds to open the door. in this way wifiAP and IR sensor will not turn on.
  • On Keypad Function
    • Press "****" to show corrent password.
    • Press "000#" to going out.
    • Press "*#*#" to change password.
