Project Idea
Develop an IoT-based smart ventilation system that monitors air quality parameters such as temperature, humidity, and CO2 levels, automatically controlling fans or exhaust systems to maintain optimal indoor air quality. The system also allows remote monitoring and control via a smartphone app, promoting healthier and energy-efficient environments.
Project Description
The IoT-Based Smart Ventilation System utilizes sensors like DHT22 (for temperature & humidity) and MQ-135 (for air quality and CO2 levels) connected to a Node MCU ESP32 microcontroller. The collected data is transmitted in real-time to a cloud platform (Blynk) via Wi-Fi. Based on predefined thresholds, the system automatically switches on ventilation fans or exhausts through a relay module. Users can also monitor air quality parameters and manually control the ventilation system remotely through a smartphone dashboard. This project is suitable for homes, offices, labs, and industrial spaces where maintaining good air quality is essential.
