Summary of Home Security Smart Clock IoT Emergency App Notification

This article describes a DIY Home Security Smart Clock featuring real-time display of time, date, temperature, and humidity. It enables two-way communication via the Blynk app for sending messages from anywhere and includes a panic button to instantly send emergency notifications. The project works offline for basic functions and uses a custom 3D-printed case designed in Tinkercad.

Parts used in the Home Security Smart Clock:

NodeMCU
DHT-22 sensor
DS3231 RTC Module
MAX 7219 LED Matrix Display
Buzzer
Mini Push Button Switch (5-6mm)
Resistor 10k Ohm

I made a Clock that not only display Time,Date, Temp & Hum but you can send message to the clock via Mobile App (Blynk) from anywhere in the World as long as you are connected to internet. And you can also alert by Pressing Panic Button in Clock a Notification Alert will be sent to Mobile instantly through internet. Good for Home Security if you have kid or elderly person in home alone. In Emergency they can alert you by just pressing the button at the back of the Clock. It also work offline showing current time ,temp humidity. Two way communication. The case is designed in Tinkercad where all components will fit in easily.

Step 1: Components Needed

NodeMCU
DHT-22 sensor
DS3231 RTC Module
MAX 7219 LED Matrix Display
Buzzer
Mini Push Button Switch – 5-6mm
