Precise indoor humidity monitoring, ready to use immediately
The Didactum Humidity Sensor is an analog plug-and-play sensor for precise measurement of relative indoor humidity (10–95 % RH) with an accuracy of 3 % RH. It is connected via RJ11 cable to any analog port (A1…A8) of a Didactum monitoring system and automatically detected thanks to AutoSense – separate configuration of the connection type is not necessary.
The sensor cannot be operated independently, but is always used together with a Didactum monitoring system, which records and visualizes the measured values and automatically triggers alarms if required.
Reliable humidity monitoring for sensitive environments
The sensor helps maintain suitable humidity conditions for equipment and inventory in a wide variety of industries.
Data Centers & Server Rooms
Monitoring of humidity to prevent condensation that can damage sensitive electronics.
Industrial Automation
Maintaining optimal environmental conditions in factories, warehouses and production facilities.
Greenhouses & Indoor Farming
Important for controlling the humidity required for plant growth.
Plug-and-Play
Automatic detection at the analog port, no additional configuration required.
Three ways to mount
The sensor can be mounted in different ways depending on the location of use.
Adhesive mounting
The sensor is attached directly to the desired surface using the included adhesive sticker.
Screw mounting
Alternatively, the sensor can be mounted on walls using the included screw.
Mounting bracket
For flexible positioning, the sensor can be attached to a mounting bracket, either glued or screwed.
The sensor is suitable for indoor mounting as desktop or wall mounting.
More sensors via the sensor expansion unit
If the analog ports of the monitoring system are no longer sufficient, the number of sensors can be easily increased.
Each sensor expansion unit connected to the Didactum monitoring system via the CAN bus adds 8 additional analog sensor ports. Sensors connected to it are automatically detected and displayed in the system – without any manual configuration.
Full control over thresholds, trends and automation
The sensor integrates seamlessly into the Didactum web interface and provides precise measured values and actionable insights.
- Individual threshold values (Lower Critical, Lower Warning, Normal, Upper Warning, Upper Critical) per sensor
- Logic schemes for automated actions when threshold values are exceeded
- Clear, individually configurable dashboard
- Graphical trend display and continuous logging of measured values
- Notifications via email, SMS, SNMP trap and other channels
Application areas of the humidity sensor
- Server room and technology cabinet monitoring to prevent condensation and moisture damage
- Industrial automation to ensure optimal production and storage conditions
- Greenhouses and indoor farming with defined humidity requirements
- Extension of existing monitoring landscapes (Zabbix, PRTG, Nagios)
- Retrofitting additional measuring points via the expansion unit
- Verifiable humidity logging for audits and compliance

To the tutorial →Frequently Asked Questions
How is the humidity sensor connected?
The sensor is connected via RJ11 cable to any analog port (A1…A8) of a Didactum monitoring system. Thanks to AutoSense, it is automatically detected; manual configuration of the connection type is not necessary.
How accurately does the sensor measure?
The sensor achieves an accuracy of 3 % RH and covers a measuring range of 10 % to 95 % relative humidity indoors.
How far away from the monitoring system can the sensor be mounted?
The maximum distance to the monitoring system or to a sensor expansion unit is 50 m.
Can the sensor be operated independently, without a monitoring system?
No. The humidity sensor does not provide its own display or evaluation and must always be used together with a Didactum monitoring system, which records and processes the measured values.
Can multiple humidity sensors be used simultaneously?
Yes. Each analog port of the monitoring system can accommodate one humidity sensor. If the existing ports are not sufficient, the number can be increased by 8 additional analog ports via a sensor expansion unit. Daisy-chaining multiple humidity sensors together is not possible; each sensor requires its own analog port.
How is the sensor mounted?
The sensor can either be attached directly to a surface using the included adhesive sticker, screwed to a wall using the included screw, or attached to a mounting bracket that is glued or screwed.
