Didactum CAN combination sensor – temperature, pressure, and humidity monitoring for demanding environments

Didactum CAN Combo Sensor – Temperature, Pressure, and Humidity Monitoring

Continuous monitoring of climatic parameters is essential in modern data centers, server rooms, clean rooms, as well as in museums, archives, production facilities, or pharmaceutical environments. The Didactum CAN Combo Sensor combines the measurement of temperature, humidity, and pressure in one compact module, providing precise real-time data for comprehensive climate monitoring. With integrated dew point calculation and data logger functionality, it is a future-proof all-in-one solution for professional monitoring projects.

Functionality and Benefits

The combo sensor simultaneously measures three key parameters:

Temperature: continuous real-time monitoring, configurable individual thresholds
Humidity: relative humidity monitoring with alarms when critical values are exceeded
Pressure: monitoring of air and room pressure for HVAC and clean room applications

All measurement values are displayed in the Didactum web interface and can be integrated into dashboards, alarm rules, or automation schemes.

Dew Point Calculation

A core feature of the combo sensor is automatic dew point calculation. This considerably reduces the risk of condensation damage – essential in archives, museums, data centers, or pharmaceutical environments. Through this proactive monitoring, damage to sensitive IT equipment or valuable inventory can be effectively prevented.

Temperature Data Logger and Recording

The integrated temperature data logger allows the storage of all measured values on an SD card with up to 500 GB capacity. This function is ideal for compliance requirements, audits, or for documentation of climatic conditions. At the same time, trend analyses can be generated to enable long-term optimizations in facility or IT operations.

CAN-Bus for Scalability

For use in larger infrastructures, the combo sensor features a CAN-Bus interface. Up to 32 sensors can be networked in a daisy chain, allowing efficient monitoring in large-scale installations such as data centers or production plants. With cable lengths of up to 225 meters, extensive areas can also be easily covered.

Alarm and Notification System

E-mail alerts: notification to administrators
SMS alerts: via GSM or LTE gateway
SNMP traps: integration into Nagios, PRTG, Zabbix, OpenNMS, IBM Tivoli
Logical actions: control of connected relays, air conditioning, or ventilation systems

Typical Applications

Data centers & server rooms: climate protection for sensitive hardware
Clean rooms & laboratories: pressure and climate control for stable production conditions
Pharma & food: cold chain and quality control
Museums & archives: climate monitoring to preserve cultural assets
Building technology & HVAC systems: central climate control and monitoring
Agriculture & greenhouses: monitoring temperature, humidity, and pressure for optimal plant growth

Scalability and Efficiency

The ability to deploy multiple combo sensors in a daisy chain significantly reduces installation costs and cabling efforts. The sensors are automatically detected (AutoSense), integrated into the monitoring system, and can be configured centrally. This ensures scalability while guaranteeing maximum operational reliability.

Economic Benefits

Companies benefit in multiple ways from using the Didactum CAN Combo Sensor:

Reduction of risks such as overheating, condensation damage, or overpressure
Optimized energy efficiency through targeted climate and pressure management
Complete documentation for audits, quality assurance, and compliance
Cost savings through proactive maintenance and precise data analysis
