IoT-Enabled Smart Restroom and Septic Tank Hygiene Management System with Odor Control

In order to improve cleanliness and minimize manual involvement, this study proposes an automated hygiene management system for septic tanks and public toilets. The system incorporates PIR sensors to identify restroom occupancy, sophisticated odor sensors to monitor air quality, and high-pressure water jets for effective cleaning. An automated aroma dispenser is activated when restroom stink levels surpass a threshold of 15 parts per million. The machine starts more sprays at 10- and 20-minute intervals if the stink doesn”t go away. If the odor persists, maintenance staff are alerted, and a complete cleaning cycle is automatically started. Additionally, when no human presence is detected, the PIR sensor initiates automatic flushing following restroom usage. The system regularly checks odor levels in septic tanks between 50 and 100 parts per million. When the threshold is exceeded, contaminants can be pushed out through an automatic drainage system because high- pressure water jets mix the contents. This guarantees effective trash management that doesn't overlook any already-existing materials. The suggested approach addresses typical problems including poor cleaning, odor control, and waste overflow and offers a dependable and affordable way to raise hygiene standards in septic tanks and public bathrooms. It improves resource management, public health, and operational efficiency in sanitary facilities by automating critical procedures.
