Network-based temperature and humidity monitoring in the server room

Every server room generates heat, and without proper cooling, hardware quickly reaches critical limits. For SMEs in particular, temperature monitoring and humidity control are crucial parts of server room environmental monitoring. Didactum offers the sensorProbe2, an IP alarm server designed to ensure stable IT infrastructure conditions.

1. Risks of Overheating & Humidity

Excessive heat reduces hardware lifespan and causes system instability. Equally dangerous is improper humidity: levels under 30% cause static electricity while levels above 55% accelerate corrosion.

• Hard drive failure from overheating
• Static discharge damages electronics under 30% humidity
• Corrosion at >55% humidity, leading to hardware failures

2. Didactum sensorProbe2

The sensorProbe2 is ideal for small and mid-sized businesses. Equipped with a combined temperature and humidity sensor, it continuously monitors climate values in server rooms. Alarms are triggered immediately when thresholds are exceeded.

• Standalone IP alarm server – no extra software required
• Email alerts to up to 6 recipients
• SMS alerts via email-to-SMS gateway
• Full SNMP compatibility with Nagios, Zabbix, HP OpenView

3. Monitoring Integration

sensorProbe2 is fully SNMP-enabled and integrates easily into existing monitoring systems:

• Nagios and OpenNMS in enterprise setups
• WhatsUp Gold and HP OpenView for larger networks
• Central management via MIB files

4. Cooling System Monitoring

Cooling systems are critical. If an AC fails, temperatures rise dangerously within minutes. The sensorProbe2 supports dry contact inputs from HVAC systems, providing immediate alarms by email, SMS, or SNMP trap.

5. sensorProbe2 Advantages

• Compact design and easy installation
• Supports SNMPv1 with alerts and traps
• Standalone operation – no external server needed
• Expandable with dry contact inputs
• Cost-effective monitoring for SMEs

6. Practical Use

Field applications show significant reduction in hardware failures when using sensorProbe2. One company reported fewer disk failures within 6 months as overheating phases were detected early, triggering cooling system adjustments.

With the Didactum sensorProbe2, SMEs gain a professional tool for server room climate monitoring. From temperature and humidity monitoring to HVAC integration and SNMP-based alarm notifications, it provides a complete platform for risk prevention and improved operational stability.
