Background
Automated and App-Controlled Fragrance Delivery for Smarter Indoor Environments
The Smart Air Freshener System was developed to enhance indoor environments by providing an automated and customizable fragrance experience. Traditional air fresheners offer limited control and often operate on fixed intervals, which may not align with user preferences. This project aimed to introduce a smart, connected solution that allows users to personalize fragrance intensity and scheduling through a mobile application.

How We Built It
Our Approach
ESP32-Powered BLE Dispenser with Android Scheduling App
A smart fragrance dispensing system was developed using the ESP32 with integrated BLE connectivity to enable wireless communication with mobile devices. A dedicated Android application was designed to allow users to configure spray schedules and adjust fragrance intensity based on specific times and days. The system ensures reliable execution of scheduled operations while providing a simple and intuitive interface for user control. The architecture focuses on stability, ease of use, and efficient performance for daily operation.

Client Feedback
What the Client Said
"
I wanted something that actually fit into my routine rather than just spraying on a fixed timer regardless of when I'm home. Being able to set different schedules for weekdays and weekends from my phone is exactly what I needed. It runs quietly in the background, never misses a scheduled spray, and the app is genuinely straightforward to use. A small product done really well.
