The HW group HTemp‑485 Box2 is much more than a conventional temperature and humidity sensor. It is specifically designed for precise and long‑term climate monitoring in critical environments. Thanks to its durable construction, RS‑485 high‑distance communication interface, and wide measurement range, this combined sensor is one of the preferred solutions for data center operators, industrial facilities, pharmaceutical storage, and modern smart building installations.

With a temperature range from –10 °C to +70 °C and relative humidity measurement between 0 % and 100 % RH, the HTemp‑485 Box2 covers nearly all relevant application scenarios. Its precision of ±0.8 °C for temperature and ±5 % RH for humidity (at 25 °C, non‑condensing) ensures dependable monitoring of environmental conditions and compliance with industry regulations — particularly in the food and pharmaceutical sectors.

The solid IP23‑rated housing and compact dimensions of only 80 × 71 × 30 mm allow for flexible and easy installation. Even in confined technical racks or demanding production areas, the HTemp‑485 Box2 integrates seamlessly. Weighing only 76 g and consuming a mere 10 mA, this sensor is also ideally suited for energy‑optimized projects in building automation.

A key feature is its effortless Poseidon2 integration. Measured data can be stored locally or transmitted over the network using SNMP, WEB, or XML protocols. With an RS‑485 range of up to 1000 m, even remote measurement points can be captured reliably without compromising data quality.

Integration with HW group Monitoring Systems

The HTemp‑485 Box2 can be used as a standalone device or as a sensor extension for a Poseidon2 monitoring system. This flexibility allows the creation of customized monitoring solutions for a variety of applications. With SNMP support, it can easily integrate into existing network management or IT monitoring platforms such as PRTG, Nagios, or Zabbix. The web interface enables remote access, allowing climate data to be viewed and managed even hundreds of kilometers away.

Typical Applications

• Precise temperature monitoring in data centers to prevent hardware damage
• Climate control in smart building systems to optimize energy use and comfort
• Cold chain compliance in the food industry
• Pharmaceutical storage monitoring for medicines and vaccines
• Industrial environmental monitoring in production environments
• Monitoring archives or libraries to protect sensitive materials

Advantages of the HW group HTemp‑485 Box2

By combining temperature and humidity measurement, operators gain a complete climate data profile for their environmental monitoring needs. Simple integration into existing HW group systems enables scalable deployments — from single‑unit installations to complex, multi‑point networked structures.

• High‑precision measurements for quality‑critical applications
• Easy RS‑485 connectivity without additional hardware
• Energy‑efficient operation with minimal power consumption

• Scalable configuration for projects of any size
• Network‑based remote monitoring in real time

Long‑Term Storage and Data Analysis

When used with Poseidon2 systems, up to 100,000 measurements can be stored for long‑term analysis. This enables trend detection in environmental conditions within data centers or production facilities and supports data‑driven decision‑making. Such historical analysis is especially useful for audits or regulatory compliance documentation.

The HW group HTemp‑485 Box2 offers a high‑precision, reliable, and scalable solution for environmental monitoring. In an era of increasing digitalization and growing demands on data security, stable climate control is essential. Whether deployed in server rooms, smart buildings, the food industry, or pharmaceutical storage, this RS‑485 combo sensor provides the precise environmental data required for stable operation and effective quality assurance.
