HW group sensors are internationally recognized for quality, precision, and reliability in environmental monitoring. One of the most in-demand sensors from this manufacturer is the HTemp-1Wire Outdoor. This model is specifically designed for professional outdoor use and delivers precise readings under a variety of weather conditions. The sensor combines robust construction with state-of-the-art 1-Wire technology, making it an indispensable element in monitoring and smart building applications. It excels particularly in areas where temperature and humidity must be measured continuously and reliably.

The HW group HTemp-1Wire Outdoor, featuring a 3-meter RJ11 connection cable, is designed for a temperature range of –30 °C to +85 °C. It also measures relative humidity within a range of 0 to 100 % RH. This makes it suitable for almost all outdoor applications, from technical outdoor installations to logistics and storage areas, and even agricultural use. Its compatibility with devices in the Poseidon2, Ares, and HWg-STE2 series ensures seamless integration into existing measurement and monitoring systems.

Of particular note is the weatherproof metal housing that protects the HTemp-1Wire Outdoor from dust, moisture, and temperature fluctuations. Where other sensors struggle to withstand environmental stresses, this sensor delivers with long-lasting, stable construction. The high-quality materials provide durable corrosion resistance, significantly improving sensor availability in continuous operation. Thanks to its daisy-chain function, multiple sensors can be connected together to efficiently and accurately monitor even large outdoor areas.

The sensor is not only a precise measuring instrument but also an important component in modern IoT and smart building concepts. At a time of increasing demands for building energy efficiency and automation, it significantly contributes to intelligent control of air conditioning, heating systems, and ventilation units. By integrating with HW group monitoring devices such as Poseidon2 or HWg-STE2, temperature trend data can be analyzed in real time and critical thresholds detected immediately. This dramatically enhances operational security in technical outdoor installations.

Technical Features of the HW group HTemp-1Wire Outdoor

The technical design of this sensor meets the highest standards. With a measurement range of –30 °C to +85 °C, the HTemp-1Wire Outdoor covers virtually any conceivable outdoor situation.

Advantages of Using the HTemp-1Wire Outdoor Sensor

One significant advantage of the HW group HTemp-1Wire Outdoor lies in its ease of use. The device connects directly to the monitoring unit via the 1-Wire RJ11 port and is ready for operation immediately. Automatic sensor ID detection eliminates the need for complex configuration. Its daisy-chain capability allows flexible expansion of the monitoring system, enabling comprehensive supervision of large areas such as production sites, loading yards, or outdoor warehouses.

Another benefit is the high precision of the readings. Continuous temperature and humidity monitoring enables accurate analysis of climate developments over time. This is particularly relevant in agriculture or horticulture, where even small temperature fluctuations can affect plant growth or storage conditions. In industrial contexts, the sensor safeguards sensitive technical components that may be impaired by overheating or excessive humidity.

Typical Applications for HW group Sensors

• Monitoring outdoor storage and transport areas
• Climate control in greenhouses and nurseries
• Monitoring pump stations, tank facilities, and transformer stations
• Smart building connections for automated climate control
• Monitoring telecommunications facilities
• Agricultural use – temperature and humidity monitoring in open-air installations
• Building technology and environmental protection applications

Intelligent Integration into HW group Systems

The open architecture of HW group monitoring platforms allows for a wide range of applications. The HTemp-1Wire Outdoor integrates easily into Ares LTE monitoring units, enabling data transmission via mobile networks. Combined with Poseidon2 devices, it allows monitoring of larger installations via Ethernet and SNMP. Through the HWg-PDMS cloud platform or portals like SensDesk.cloud, measurements can be centrally displayed and analyzed. This improves transparency of environmental parameters and enables rapid response to deviations.

For system administrators or technicians, this means greater control and a reliable data foundation with minimal maintenance effort. Combined with alerts via email, SMS, or SNMP traps, the sensor provides a comprehensive tool for securing sensitive infrastructure. Whether for cooling systems, power plants, or telecommunications sites, the HW group HTemp-1Wire Outdoor offers an outstanding solution for increasing operational safety and facility availability.

Reliability and Durability in Focus

Long-term use in harsh outdoor environments puts high demands on materials and construction. Here, the HW group HTemp-1Wire Outdoor excels with its robust metal housing and weather-resistant sealed design. This permanently protects sensor elements from moisture, dust, and temperature shocks. The device thus meets all requirements for continuous operation in the most demanding climate situations.

The sensor is also designed for low maintenance. After initial installation and configuration via the connected monitoring device, it operates continuously in the background, transmitting its readings to the central system. Thanks to its stability, regular replacement is unnecessary – another argument for its cost-effectiveness in professional use.
