Auto Sash: Smart IoT-Powered Fume Hood for Safer, Efficient Laboratories

• 1
  Safety Risks – Manual operation increased user exposure to harmful fumes and accidental splashes.
• 2
  Energy Inefficiency – Sashes left open when not in use led to high air handling costs.
• 3
  Inconsistent Operation – Human error often resulted in improper sash positions, affecting airflow and containment efficiency.
• 4
  Lack of Smart Controls – No integration for automatic detection, monitoring, or adaptive operation.
• 5
  Limited User Convenience – Researchers often struggled to operate the sash while handling chemicals or equipment.

• 1
  Requirement Analysis – Studying laboratory workflow, user safety protocols, and regulatory standards.
• 2
  Hardware Design – Developing a motorized sash control system with sensors, buttons, and foot pedal integration.
• 3
  IoT Integration – Implementing microcontroller-based control logic with auto/manual modes and presence detection.
• 4
  Calibration Mechanism – Allowing users to customize sash levels (Open, Working, Closed) and inactivity timers.
• 5
  Safety Layer – Incorporating obstacle detection and emergency stop logic.
• 6
  Testing & Validation – Conducting multiple safety and performance tests to ensure reliability in live lab environments.

• 1
  Three-Level Calibration System – Customizable Open, Working, and Closed positions for flexible operations.
• 2
  Human Presence Detection – Automatically opens to the working level when a user approaches.
• 3
  Energy-Saving Automation – Closes automatically when inactive, reducing air handling energy costs.
• 4
  Foot Pedal Operation – Enables hands-free control when handling chemicals or instruments.
• 5
  Digital Display Interface – Provides real-time status and calibration information.
• 6
  Manual/Auto Mode Selection – Offers operational flexibility for varied lab requirements.
• 7
  Obstacle Detection System – Prevents accidents by halting sash movement if obstructions are detected.

• 1
  Reduced User Exposure – Automatic sash positioning minimized direct contact with hazardous fumes.
• 2
  Enhanced Energy Efficiency – Auto-closing mechanism reduced ventilation energy use by up to 30%.
• 3
  Improved User Experience – Hands-free operation and intuitive interface simplified daily workflows.
• 4
  Regulatory Compliance – Ensured adherence to international safety and environmental standards.
• 5
  Minimized Equipment Damage – Obstacle detection safeguarded sensitive instruments and personnel.
