Didactum Humidity Sensor for Climate Monitoring

Function and Purpose

The Didactum humidity sensor for relative humidity is a precise measuring instrument designed to monitor climatic conditions in indoor environments. It measures relative humidity in the range of 10 % to 95 % and provides reliable real-time data on the stability and quality of ambient air. The sensor has been specially developed for professional use in IT infrastructures, production facilities, and sensitive storage areas where constant humidity levels are crucial for operational safety.

By continuously monitoring relative humidity, the sensor helps to prevent risks such as corrosion, condensation, static discharge, or material deformation. This is especially important in server rooms, data centers, or telecommunications facilities, where even minor deviations from recommended climate values can cause functional disturbances. Through integration into Didactum monitoring systems, humidity can be monitored in real time, and immediate alarm notifications are triggered via SNMP trap, email, or SMS when threshold values are exceeded.

The humidity sensor is an analog plug-and-play sensor that can be directly connected to one of the analog ports (A1…A8) of the Didactum monitoring system without additional configuration. Once connected, the sensor is automatically detected, and measurement data are displayed and stored via the web-based user interface of the system. This allows not only real-time monitoring but also historical evaluations and trend analyses of climate stability.

To expand larger installations, the maximum number of connected sensors and the distance to the monitoring unit can be individually adapted using a sensor expansion unit. This makes the system scalable and easily adjustable to complex environments with multiple measurement points — such as monitoring humidity in different zones of a data center or archive.

With its high measurement precision, simple integration, and long-term reliability, the Didactum humidity sensor is an ideal solution for professional environmental monitoring applications. It ensures that sensitive equipment, materials, and systems operate under optimal humidity conditions to sustainably prevent malfunctions and quality losses.

Areas of Application

These examples demonstrate the versatility of the sensor across various fields where monitoring and maintaining optimal humidity levels is essential.

Data Centers and Server Rooms: Monitoring humidity to prevent condensation that could damage sensitive electronic equipment and cause outages or hardware failures.
Industrial Automation: Helps maintain optimal environmental conditions in factories, warehouses, and production facilities where humidity control is critical for processes, equipment lifespan, or product quality.
Clean Rooms: In pharmaceutical or electronics manufacturing, precise humidity control is required to prevent contamination or static electricity that could impair product quality.
HVAC Systems (Heating, Ventilation, and Air Conditioning): Provides real-time data for climate control systems and enables efficient humidity regulation in buildings to ensure a comfortable indoor environment.
Laboratories: Ensures that controlled environments such as research labs maintain proper humidity levels for experiments, instruments, and sample storage.
Greenhouses and Indoor Farming: Essential for regulating humidity required for plant growth and preventing mold or fungal formation.

Connecting the humidity sensor:

Installation:

Option 1

At the lower part of the sensor’s plastic housing, there is a round protrusion. It serves as a mounting point when the sensor is fastened to a wall using a screw. In the current example, it is not needed. If you plan to mount the device differently, skip this step.

Cut off the round protrusion with a knife so that the bottom side of the plastic housing is flat.

Option 2

a) Attach the sensor to the desired surface using the included adhesive pad.

or

b) Mount the sensor to the surface using a screw.

Option 3

Mount the sensor to the surface using a bracket.

The mounting bracket and the sensor can be attached either with adhesive pads or using screws and nuts.
