Story

Today's life is made easier by the arrival of the IoT in various ways. One of the things that IoT helps with is the security system. The security system created in this project is a security system using magnetic sensors. This sensor will later be installed on the door and door frame. This sensor will detect and send notifications via the owner's telegram bot when the door is opened. This sensor can also be turned on and off according to the user's wishes

Required components:

1. NodeMCU ESP8266

2. Jumper Cable, Male-Male

3. USB-A to Micro-USB Cable

4. Breadboard

5. Buzzer

6. Sensor magnetic NO

7. 5 mm LED: Blue

Software used:

1. Arduino IDE

2. Telegram

Installation Step:

1. Assemble the components according to the scheme below

2. Connect the ESP8266 to the laptop using a USB A to Micro USB cable

3. After the circuit is complete, create program code in the Arduino IDE by adjusting the circuit

4, Open telegram and create a new bot in BotFather, after that, search for Telegram ID on IDBot

5. adjust the ssid, pass from your WiFi network, and enter the ID and telegram bot into the program code

6. Upload the finished program to the ESP on the Arduino IDE

7. Then run the circuit to test whether it is successful or not

To make it clearer, you can watch the following video:
