Design and Fabrication of Solar Powered Smart Air Cooler

Abstract

This paper introduces a solar-powered smart air cooler designed to offer a comfortable and energy-efficient cooling experience. The system runs on solar energy, which helps reduce electricity usage and is especially useful in places with frequent power outages. It’s built with smart features that respond to real-time conditions like temperature, humidity, and even user presence using a PIR sensor. A PMDC motor is used and the system is managed by an ESP32 microcontroller. The cooler can be monitored and controlled remotely through the Blynk interface, allowing users to adjust settings from anywhere. Features like automatic shut-off, mist-based cooling, and humidity-based water control make it intelligent and easy to use. This cooler provides an eco-friendly, modern solution for keeping spaces cool while promoting energy savings and environmental care.
