In the digital era, server rooms serve as the hub for data storage and processing. Their environmental stability directly affects equipment lifespan and business continuity. Excessive temperature can easily cause server overheating and crashes, while improper humidity may lead to static electricity or corrosion. Through precise monitoring and intelligent linkage, server room temperature and humidity sensors have become a core component of DCIM monitoring systems. With reliable performance, the Nexisense series supports a full-chain solution from local display to cloud-based management, helping enterprises build efficient environmental control for server rooms. This article provides a detailed explanation of its technical and practical value.

Definition of Server Room Temperature and Humidity Sensors

A server room temperature and humidity sensor is a monitoring device designed specifically for data centers. It simultaneously captures air temperature and relative humidity and converts them into standard output signals. It is commonly integrated into DCIM monitoring systems, covering power, environmental, and security parameters.

According to the national standard GB2887-89, Class A server rooms require a temperature of 22±2°C and humidity of 45–65% RH. Sensors ensure these parameters remain stable, preventing abnormalities caused by equipment heat sources such as server dissipation.

Working Principle of Server Room Temperature and Humidity Sensors

The principle is based on high-precision measurement units. The temperature module uses platinum resistance or thermistor elements to detect thermal equilibrium changes, while the humidity module uses capacitive polymer film technology, where water molecule absorption causes capacitance variation. Internal circuits compensate for environmental interference and output linear data.

Within a DCIM system, sensors collect data in real time and link with leak detection and power supply modules. When anomalies occur, multiple alarm methods are triggered to ensure rapid response.

Structural Analysis of Server Room Temperature and Humidity Sensors

The structural design emphasizes industrial durability. A typical 86-type wall-mounted enclosure is equipped with an LCD screen and buttons for convenient on-site configuration of addresses and thresholds. Probes can be built-in or externally extended, and stainless-steel protective filters provide dust resistance.

Wiring uses screwless terminals, compatible with 0.3–2.0 mm² cables. Output interfaces support RS485 and analog signals (4–20 mA / 0–5 V / 0–10 V), enabling easy integration with PLCs or cloud platforms. Nexisense devices feature modular design for flexible installation.

Advantages of Server Room Temperature and Humidity Sensors

High accuracy and reliability: Temperature ±0.1°C, humidity ±2% RH, with strong anti-interference capability.

Intuitive display: Large screen for real-time viewing and button-based local configuration.

Diverse transmission: RS485 networking with cloud-based remote support.

Timely alarms: Multi-channel notifications when thresholds are exceeded to prevent risks.

Excellent scalability: Integration with DCIM systems covering temperature, humidity, water leakage, and more.

These advantages enable 24/7 uninterrupted monitoring and significantly reduce the burden of manual inspections.

Application Scenarios of Server Room Temperature and Humidity Sensors

Data center core areas: Monitor server heat dissipation to maintain constant temperature and humidity.

Power distribution rooms and UPS areas: Prevent thermal anomalies in power equipment.

Multi-site server rooms: Unified management through cloud platforms with cross-regional visibility.

Combined with water leakage detection and access control, they form a comprehensive DCIM system that supports predictive maintenance.

Measurement Methods of Server Room Temperature and Humidity Sensors

Continuous automatic measurement: Wall-mounted installation near equipment, avoiding direct airflow from heat sources. Probes are exposed to ambient air for real-time sampling.

Data uploaded to cloud platforms: Support for local software or remote apps to view curves and export reports. Thresholds can be preset, and anomalies trigger immediate alarms via SMS, email, or phone calls.

Maintenance and Care Guidelines for Server Room Temperature and Humidity Sensors

Maintenance is simple: Regularly clean the probe and check wiring connections. Annual calibration using standard instruments is recommended.

Avoid direct sunlight and strong electromagnetic interference. Cloud platforms monitor device status to promptly detect offline conditions.

Nexisense designs emphasize durability, reducing maintenance frequency.

Technical Parameters of Server Room Temperature and Humidity Sensors

Temperature range: -40 to +80°C (expandable), accuracy ±0.1°C; Humidity range: 0–100% RH, accuracy ±2% RH.

Output: RS485 (Modbus-RTU), 4–20 mA / 0–5 V / 0–10 V; Display: LCD screen; Protection: IP65+; Power supply: DC 12–24 V.

These parameters comply with Class A server room standards, ensuring reliable operation.

Overall Value of DCIM Monitoring Systems

With temperature and humidity sensors as the core, DCIM systems expand to cover power supply, water leakage, and security. Key advantages include round-the-clock monitoring, intelligent early warning, and centralized management.

Remote platforms break time and space limitations, supporting trend analysis and decision-making. They reduce failure rates and safeguard data security.
