Overview: Smoking sensors in smart buildings are IoT-enabled, high-precision detection devices that identify fire hazards or smoke particles and instantly alert occupants and building management via wireless, centralized networks. Unlike traditional alarms, these devices, often using photoelectric or laser technology, provide real-time monitoring, reduce false alarms through AI, and integrate with HVAC systems to enhance safety. 

Key Features and Functions:

• Real-time Alerts & Remote Monitoring: Send instant notifications to mobile devices, allowing monitoring even outside the building.
• System Integration: Automatically trigger, or work with, other systems, such as closing fire doors, lowering elevators, or shutting down HVAC units to limit smoke spread.
• AI-Powered Accuracy: Use advanced, sometimes AI-enabled, sensors to distinguish between actual smoke/fire and environmental factors like steam or cooking fumes.
• Environmental Monitoring: Advanced models can monitor air quality and detect volatile organic compounds (TVOC) in addition to smoke.
• Vape and Smoke Detection: Specific sensors exist to detect cigarette, cannabis, and e-cigarette vapor. 

These intelligent devices are crucial for proactive fire safety and maintenance in modern commercial, industrial, and residential environments.
