Semi Smart Home System (AVR – ATmega32)

A home automation prototype built using ATmega32 (AVR) microcontroller that performs basic smart control functions based on sensor inputs.

Features:

️ Temperature Monitoring:

Using the LM35 sensor to continuously measure room temperature. If it exceeds a defined threshold, a buzzer is activated automatically for alerting.

Auto Lighting Control:

An LDR sensor detects ambient light levels. When it gets dark, an LED light is turned on automatically to simulate smart lighting.

Technologies Used:

ATmega32 Microcontroller

LM35 Temperature Sensor

LDR (Light Dependent Resistor)

Buzzer, LED

C Language, AVR-GCC

Simulation: Proteus
