Home Smell Sensor System for Laundry

I'm looking for an innovative system that can detect unwashed clothes in my home using smell sensors. This project is aimed at creating a system that can identify clothes that are typically worn daily, such as underwear, t-shirts, and pants. The system should have a visual indicator that alerts me when unwashed clothes are present.

Key Requirements:
- Design and build a smell sensor system for detecting unwashed clothes
- System should be suitable for home use
- Visual alert system
- Focus on detecting casual daily wear

Ideal Skills:
- Experience in sensor technology and system design
- Knowledge in creating home-friendly systems
- Ability to design a user-friendly visual alert system
- Understanding of detecting specific types of items

The visual alert system should use LED lights for indicating detection. The system should be powered by a plug-in power source. The system should operate as a standalone unit with no integration with other devices. The sensors should be placed in the laundry basket. The system should achieve a moderate level of accuracy in detecting unwashed clothes, balancing precision and cost. The system should include a mobile app for interaction. Include push notifications for detected unwashed clothes. The mobile app should have a simple and minimal interface. Include basic data logging to track detection events and provide simple historical insights. The system will support one laundry basket or room for detection.
