• Extra Dehumidifier – Further ensures a dry and breathable atmosphere.

Whether you choose basic or advanced ventilation, UnderPearl shelters provide uncompromised air quality, protection from external threats, and a controlled climate for long-term habitation.

To ensure optimal air quality, safety, and real-time monitoring, UnderPearl shelters are equipped with state-of-the-art sensor systems that track critical environmental conditions both inside and outside the shelter.

Internal Sensors (Cell Sensors) (Real-Time Monitoring for a Safe Interior)

Inside the shelter, advanced sensors continuously measure key air quality parameters to maintain a healthy and habitable environment:

• Temperature (T) & Humidity (RH) – Ensures climate stability and prevents condensation.
• Oxygen (O₂) & Carbon Dioxide (CO₂) – Monitors air composition to prevent suffocation risks.
• Carbon Monoxide (CO) – Detects toxic gases that could be life-threatening.
• Particulate Matter (PM) – Tracks fine dust and pollutants for clean air control.
• Volatile Organic Compounds (VOC) – Identifies hazardous airborne chemicals.
• Explosive & Flammable Gas (EX) – Prevents fire and explosion risks.
• Overpressure Sensor (DP) – Ensures proper internal pressure regulation for a sealed and secure environment.

External Sensors (Early Detection of Outside Threats)

To keep you informed about external conditions, UnderPearl’s external sensor suite provides continuous data on air quality and potential hazards outside the shelter:

• Temperature (T) & Humidity (RH) – Tracks external climate conditions.
• Oxygen (O₂) & Carbon Dioxide (CO₂) – Monitors breathable air levels.
• Carbon Monoxide (CO) & Particulate Matter (PM) – Detects harmful pollutants.
• Volatile Organic Compounds (VOC) – Identifies hazardous chemicals in the air.
• Explosive & Flammable Gas (EX) – Warns of potential external fire or explosion threats.

Complete Protection, Inside and Out

With real-time sensor monitoring, UnderPearl ensures a controlled, safe, and habitable space no matter what happens outside. The combination of internal and external sensors allows for proactive safety measures, automatic air regulation, and immediate alerts in case of environmental threats.
