The HW group THPVoc 1W‑UNI is a modern and compact environmental sensor that simultaneously measures temperature, humidity, air pressure, and air quality (VOC). This high‑precision multi‑sensor device is an ideal solution for monitoring indoor climate conditions where reliability and accuracy are essential. From data centers to office buildings, educational institutions, and laboratories, this sensor offers comprehensive environmental monitoring that enhances both comfort and safety within buildings.

With its 1‑Wire UNI interface, the THPVoc 1W‑UNI easily integrates into HW group devices such as Poseidon2, STE2 R2, or Ares 12 LTE. All measured values — temperature, humidity, pressure, and VOC — are transmitted digitally in real time and can be displayed and analyzed directly via the web interface or through the IoT portal SensDesk.com.

The sensor’s compact design (40 × 40 × 20 mm), high‑quality measuring components, and IP30‑rated housing make it ideal for indoor use. A 3‑meter RJ11 cable provides both power supply and data transmission, making installation and maintenance straightforward and efficient.

Precise Temperature and Humidity Measurement

With an extended measurement range from –30 °C to +70 °C, the THPVoc 1W‑UNI reliably captures both cold and warm indoor environments. Relative humidity is measured from 0 % to 100 % RH with high accuracy. This combination allows precise monitoring and control of climate‑relevant systems such as HVAC units, dehumidifiers, and automated ventilation systems. In data centers, this functionality protects sensitive hardware against condensation, corrosion, and electrostatic discharge, while in offices or classrooms it promotes comfortable and healthy working conditions.

Air Pressure and VOC Monitoring

A key feature of the THPVoc 1W‑UNI is its integrated air pressure measurement from 30,000 Pa to 110,000 Pa. This enables accurate barometric tracking, which plays an important role in analyzing indoor climate fluctuations and airflow patterns.

Additionally, the sensor includes a VOC (Volatile Organic Compounds) sensing element that measures concentrations up to 60,000 ppb. These measurements provide valuable insights into indoor air quality, as high VOC levels can indicate poor ventilation or pollutant sources. In modern building management systems, the VOC sensor serves as an early‑warning component, triggering automated ventilation or issuing alerts when elevated contamination levels are detected.

Integration with HW group Systems

The THPVoc 1W‑UNI is designed for seamless integration into existing HW group monitoring systems. Once connected via RJ11, it is automatically detected by the connected device. Data can be viewed in real time through the web interface of Poseidon2, STE2 R2, or Ares units. Thresholds for VOC, humidity, or temperature can be customized, and alarms are automatically triggered via email, SMS, or SNMP trap when limits are exceeded.

Example of Practical Application

In a modern office building, the THPVoc 1W‑UNI continuously measures room temperature, humidity, and CO₂‑equivalent VOC values. If elevated VOC levels are detected in a conference room, the system automatically signals the central ventilation controller to increase air exchange. This improves air quality without wasting energy through unnecessary continuous ventilation. The sensor thus supports not only occupant health and productivity but also energy efficiency.

The HW group THPVoc 1W‑UNI is a powerful, multifunctional environmental monitoring sensor for professional use. Its ability to simultaneously measure temperature, humidity, pressure, and VOC values makes it indispensable for data centers, smart buildings, and laboratory environments. Integrated with innovative HW group platforms such as SensDesk.com, it provides a future‑ready solution for real‑time environmental monitoring, energy optimization, and quality management.
