Maico PP 45 HY Humidity Sensor

The Maico PP 45 HY is a capacitive room humidity sensor designed for precise measurement and control in HVAC, building automation, and ventilation systems. It provides a linear 0-10 V DC output signal proportional to 0-100% relative humidity, ensuring reliable integration with building management systems.

Advantages

High accuracy of ±3% RH in the 10-90% RH range at 20°C; robust ABS plastic housing with IP30 protection; easy wall mounting and screw terminal connection; low power consumption of max. 10 mA; wide operating temperature range from 0 to +50 °C.

Suitable for

• Humidity monitoring in residential and commercial ventilation systems
• Demand-controlled ventilation based on room humidity
• Integration into HVAC automation and building management systems
• Use in offices, schools, hospitals, and industrial environments
