Two essential projects for home automation and safety:
Door Control with WiFi & LPG Flame Detection.
Simulation and diagrams included.
A smart security system combining a password-protected keypad, servo lock, and real-time temperature monitoring. Controllable via WiFi using RemoteXY.
A critical safety system for homes. It detects high gas concentrations or open flames and immediately triggers a buzzer alarm and activates a water pump.
