Design and Implementation of Dual Fan System

The project titled “Design And Implementation Of Dual Fan System” leverages the Peltier effect to develop an efficient and eco-friendly system for room humidification. This system uses a NodeMCU microcontroller for IoT-based monitoring and control. The design incorporates a 12V 10AH relay, SMPS (Switched Mode Power Supply), a 12V blower fan, a Peltier air cooler kit, and a temperature sensor. The primary feature is the temperature- based automatic control of the Peltier cooler and fan, optimizing performance and energy consumption. This smart humidifier aims to improve air quality and maintain desired humidity levels in indoor environments. Air quality and optimal humidity are critical for healthy living and comfort, especially in indoor settings. Conventional humidifiers are often bulky, energy-intensive, and lack intelligent control mechanisms. This project introduces a compact, energy-efficient, and intelligent room humidifier system using Peltier technology. The Peltier module, known for its dual heating and cooling capability, plays a pivotal role in this system. Paired with IoT-enabled NodeMCU, the system ensures real-time temperature monitoring and adaptive control, making it an innovative solution for modern indoor air quality management.
