The temperature & humidity sensor
Swiss Made Sensor.
The humidity sensor component inside the ServersCheck sensor is made in Switzerland. It is factory calibrated against several national standards. Final assembly and testing is done in Thailand unless the TAA version is chosen.
Sensor Drifting & Calibration.
How It works.
The ENV-THUM sensor connects to the the base unit. This makes the device an ethernet temperature & humidity sensor. The sensor measures the relative humidity and temperature. This sensor is designed to monitor conditions in server rooms and other sensitive area's. Humidity reading is done through the external probe. Alerting via email, SMS, voice call. Integrates with BMS platforms using the Modbus TCP protocol. Or with NMS systems through SNMP GET and SNMP TRAPS.

Tips For Avoiding Humidity-Related Server Damage.Most servers will support non-operating humidity in the range of 90%. Actual operating tolerances are quite a bit lower. While moisture in the air isn't necessarily a problem. "Condensing humidity" is water vapor that turns to actual water droplets. It can short out a server as quickly as if you had squirted it with a water hose.
Too low humidity levels allow for the build up of static electricity. This static electricity can result in permanent equipment damage. Simply by just touching the IT equipment and causing an ESD discharge.
Humidity conditions are directly related to the temperature in the server room. Water vapor begins to condense once the ambient temperature reaches the "dew point." Because temperatures can vary widely during the day and night, your computer room's dew point changes regularly. It means that you can go from normal operations to "meltdown" in a matter of minutes.
It's important implement a 24/7 monitoring system for relative humidity.
Avoid humidity and consendation damage your systems. Install a humidity monitoring system. ServersCheck offers a sensor for monitoring not only humidity but also temperature 24x7. It is a digital thermometer and hygrometer with a high acurracy as per above specs. The sensor components are made in Switzerland and are factory calibrated before mounting onto our PCB.
The sensors connects to the base unit. It checks non stop for humidity levels against your defined thresholds. Upon breach of your upper or lower limits, it can alert multiple people via email, SMS and voice calls.
It becomes a Modbus humidity sensor by enabling the Modbus protocol in the base unit. The Modbus TCP protocol allows for integration with Building Management Systems.
Through SNMP the sensor can be integrated with NOC network management systems.
