Didactum Humidity Sensor

Continuous humidity monitoring is an essential factor for safe operation of data centers, server rooms, industrial environments, warehouses, or archives. Even small deviations can cause damage to IT systems or stored goods. The Didactum Humidity Sensor, with its high measurement accuracy and compact design, provides a reliable solution for real-time climate monitoring.

Technical Features

• Accuracy: ±3 % relative humidity (RH)
• Operating range: -40 °C to +100 °C
• Additional functions: dew point calculation, frost point measurement, and determination of absolute humidity
• Power consumption: only 60 mW – energy-efficient and low-power
• Dimensions: 60 × 18 × 18 mm – compact and space-saving
• Cable length: extendable up to 50 meters
• Connection: RJ plug with AutoSense capability
• Integration: SNMP v1/v2c/v3 for Nagios, PRTG, Zabbix, etc.

Integration & Installation

With AutoSense support, every Didactum monitoring system detects the humidity sensor immediately after connection. Individual thresholds and alarm levels can be configured via the web-based interface. Alerts are sent via e-mail, SMS, or SNMP trap. Thanks to flexible mounting (wall, ceiling, rack, or HVAC system) and optional cable extension, the sensor is highly versatile.

Application Areas

• Data centers & server rooms: prevention of condensation and failures caused by humidity damage.
• Industrial facilities: ensuring stable production conditions through humidity monitoring.
• Clean rooms & laboratories: compliance with precise humidity levels for quality and process reliability.
• HVAC systems: integration for energy-efficient heating, ventilation, and air conditioning control.
• Warehousing & logistics: protection of temperature-sensitive goods such as pharmaceuticals and food.
• Greenhouses: optimized climate monitoring for healthy plant growth.
• Museums & archives: preservation of delicate exhibits and documents.

Sensor Functions in Detail

• Dew point calculation: prevention of condensation risks.
• Frost point determination: protection in cooling or freezing equipment.
• Data logging: storage of climate values in combination with Didactum monitoring systems on SD card (up to 500 GB).
• Logic schemes: automatic actions based on humidity levels (e.g., activating ventilation or sending alerts).

Economic Benefits

The Didactum Humidity Sensor prevents damage from moisture or condensation. Beyond safeguarding hardware and facilities, it also contributes to energy efficiency by enabling targeted HVAC operation based on precise real-time data. This ensures cost savings and extends the lifespan of critical infrastructure.
