Application of DB5101GS Temperature and Humidity Sensor

In a Provincial-Level Core Data Center

In data center operation and maintenance (O&M), precise control of temperature and humidity is critical to ensuring the stable operation of core hardware such as servers. Excessively high or low temperature and humidity may lead to equipment failures, data loss, or service interruptions. The DB5101GS, a wall-mounted temperature and humidity sensor specially designed for harsh indoor environments, has demonstrated outstanding value in the environmental monitoring system of a provincial-level core data center, thanks to its high accuracy, high stability, and flexible adaptability.
This provincial-level core data center hosts critical services such as government cloud and enterprise cloud, requiring 24/7 uninterrupted operation throughout the year. According to industry standards like ASHRAE TC 9.9, its core computer rooms demand temperature maintenance at 18-27℃ (deviation ≤±2℃) and relative humidity (RH) at 40-60% RH (deviation ≤±5% RH). Previously, the traditional sensors used in the data center had issues including insufficient accuracy (humidity deviation up to ±5% RH) and slow response, which repeatedly caused undetected local temperature and humidity anomalies and led to brief server outages. Therefore, the O&M team needed to replace them with sensors featuring high accuracy, high stability, and compatibility with the existing monitoring system.

Three Core Reasons for Choosing the DB5101GS
1. Accuracy & Stability: Meeting Core Equipment Operation Requirements
The DB5101GS achieves a humidity measurement accuracy of ±2.0% RH (0-90% RH range) and a temperature accuracy of ±0.2℃ (at 25℃/77°F), fully complying with the data center’s deviation requirements.
2. Response Speed & Output Modes: Adapting to Real-Time Monitoring Systems
The DB5101GS has a humidity response time of ≤8s and a temperature response time of ≤2s, enabling it to quickly capture temperature and humidity fluctuations caused by equipment load changes or air conditioning failures in the computer room.
3. Installation & O&M: Aligning with Computer Room Space and Management Needs
The DB5101GS adopts a wall-mounted design (dimensions: 130.0×120.0×45.0mm), which can be easily installed on room walls or next to cabinets without occupying equipment layout space. Its dual-line LCD display supports simultaneous display of real-time temperature and humidity data, allowing O&M personnel to check on-site without connecting to a terminal, thus improving inspection efficiency.

Deployment Results
Since the deployment of the DB5101GS, the data center has achieved a comprehensive upgrade in temperature and humidity monitoring:
Enhanced Equipment Stability: The room temperature and humidity have long remained within the optimal range of 18-24℃ and 45-55% RH. The failure rate of servers due to environmental issues has decreased by 72%, and no outages caused by temperature/humidity anomalies have occurred throughout the year.
Optimized O&M Efficiency: The sensor’s long-term stability extends the calibration cycle from 3 months to 12 months, reducing O&M workload by 60%. The LCD on-site display function cuts inspection time by 50%.
More Accurate Monitoring System Linkage: After connecting to the data center’s intelligent monitoring platform via the RS485 interface, temperature and humidity data are uploaded to the O&M center in real time. When anomalies occur (e.g., temperature >27℃), the system triggers an alarm and links to air conditioning adjustments within 10s—three times faster than the previous response speed.

With "high-precision measurement, long-term stability, and flexible adaptability," the DB5101GS perfectly meets the strict temperature and humidity monitoring requirements of data centers. Its wall-mounted design, dual-line LCD display, and multiple output modes not only meet the room space layout needs but also adapt to the linkage needs of intelligent monitoring systems. It provides reliable environmental data support for the stable operation of data centers, making it an ideal choice for temperature and humidity monitoring in harsh indoor environments (such as data centers and clean rooms).
