The HW group Temp‑1Wire Outdoor is a specially designed digital temperature sensor for outdoor use. With a wide measurement range from –50 °C to +125 °C, it is ideal for demanding applications such as environmental monitoring, industrial process control, food and pharmaceutical logistics, and supplemental climate data collection in IT infrastructures. Its rugged stainless‑steel housing and IP67 protection rating ensure reliable performance even under extreme weather conditions.

Made from corrosion‑resistant stainless steel (grade 17241), the sensor is not only mechanically durable but also hygienic and easy to clean — a key advantage in the food and pharmaceutical industries. The fully sealed, dust‑ and waterproof construction ensures accurate and stable readings, even in rain, snow, or high humidity.

The Temp‑1Wire Outdoor features an RJ11 connector and a proven 1‑Wire communication interface, allowing fast and seamless integration with HW group monitoring systems such as Poseidon, Ares, or HWg‑STE. Power supply and data transmission are combined within a single cable, simplifying installation and reducing maintenance requirements.

Integration with HW group Systems

The Temp‑1Wire Outdoor is fully compatible with standard HW group monitoring devices. Once connected to the RJ11 port of a Poseidon2, Ares, or HWg‑STE system, the sensor is automatically recognized and ready for immediate use. Data can be viewed in real time via the device’s web interface. Using the SensDesk.com IoT portal, data can also be archived, analyzed, and exported for reporting. Automatic alerts via email, SMS, or SNMP traps can be configured to trigger when predefined temperature thresholds are exceeded.

Practical Example

In an agricultural facility, the Temp‑1Wire Outdoor continuously measures the outside temperature around a cold‑storage area. If temperature deviations are detected, the system automatically sends a notification, enabling immediate corrective action. This ensures consistent product quality and prevents potential losses.

The HW group Temp‑1Wire Outdoor is a professional outdoor temperature sensor distinguished by its precision, durability, and versatility. Its IP67 protection rating and high‑quality stainless‑steel construction make it ideal for industries requiring reliability and hygienic safety. Whether in food production, pharmaceuticals, research, or environmental monitoring, this sensor consistently delivers accurate and stable measurement data — even under the most challenging conditions.
