The Expella Humidity Sensor is an innovative product that detects humid air and automatically activates an exhaust fan, helping to prevent condensation and the formation of mould.

The patented technology was developed in Australia and is ideal for bathroom and laundry applications. The Humidity Sensor has an elegant slim-line profile and minimal design, and it can be discreetly mounted onto the ceiling. By automating exhaust fan activation this product helps make buildings healthier, more comfortable and more energy efficient.

The Humidity Sensor is suitable for new builds, bathroom and laundry renovations, or it can be retro-fitted into an existing space. The product is easily installed by a licensed electrician and is designed to work in conjunction with an exhaust fan or ducted ventilation system (available separately).
