The LoRa-based smart public toilet solution utilizes wireless IoT technology to monitor restroom conditions (odors, foot traffic), equipment status, and emergencies in real time. The system automatically adjusts ventilation, lighting, and water usage, improving hygiene while reducing energy consumption and maintenance costs, ultimately providing a more comfortable and safer public service experience.

Industry Pain Points

🚻 Poor Hygiene Management

Unpleasant odors and unclean conditions cannot be monitored in real time, negatively impacting urban image.

🔧 Low Operational Efficiency

Manual inspections are required for fault reporting, resulting in slow response times.

📊 Outdated Management Methods

Lack of data support makes it difficult to optimize cleaning schedules and supply replenishment.

âš  Potential Safety Hazards

Emergency situations (e.g., falls, sudden illnesses) cannot be promptly alerted.

Program Architecture

  • ✅ Smart Sensing Layer (Environment + Equipment Monitoring)
    Environmental sensors: Monitor ammonia, hydrogen sulfide levels (quantifying odors), temperature, humidity, and foot traffic.
    Equipment status monitoring: Track usage and faults in water valves, hand dryers, and soap dispensers.
    Safety monitoring: Fall detection radar and emergency help buttons.
  • ✅ Network Transmission Layer (Stable Communication)
    LoRa gateways: Single gateway covers a 3 km radius (urban areas) with strong penetration through concrete structures.
    Multi-protocol compatibility: Supports RS485/Modbus for integration with existing sanitation equipment.
  • ✅ Cloud Management Platform (Intelligent Management)
    Smart supply alerts: Monitor tissue/soap levels and automatically generate restocking orders.
    Maintenance dispatch center: Automatically assign repair tasks, reducing response time by 70%.
  • ✅ Application Layer (User Services)
    Navigation screens: Display available stalls and air quality, support QR code-based paper dispensing.
    Energy-saving strategies: Automatically reduce lighting/ventilation frequency during low-traffic hours.
