The Pax Passad 30 fan moisture and presence sensor is a ventilation accessory designed to enhance air quality control in residential and commercial spaces. This white circular sensor measures 100 mm in diameter and integrates with compatible ventilation systems to detect both humidity levels and human presence. The moisture detection function monitors ambient humidity to help prevent mold growth and maintain optimal indoor air conditions, while the presence sensor automatically adjusts ventilation based on room occupancy to improve energy efficiency.

Constructed with durable materials suitable for long-term installation, this sensor features a discreet white finish that blends with most interior designs. The Pax Passad 30 operates within standard temperature ranges for indoor environments and connects to ventilation units using industry-standard protocols. Its compact design allows for ceiling or wall mounting in bathrooms, kitchens, offices, and other areas requiring controlled ventilation. The sensor provides reliable detection without requiring direct user interaction once installed, making it a practical addition to automated ventilation systems focused on maintaining consistent air quality and reducing unnecessary energy consumption.
