This IoT‑enabled system provides precise remote monitoring of temperature, humidity, liquid, power, intrusion, and smoke via IP networks and sends early warnings to prevent downtime. Imagine a small IT company’s server room: a cooling system fails, and the temperature rises unnoticed. Without monitoring, servers could overheat, leading to data loss and costly repairs. With ENVIROMUX® 1‑Wire, you receive instant alerts via email, SMS, or SNMP, allowing immediate action. It supports up to 24 1‑Wire sensors in any combination (temperature, humidity, dew point, or digital inputs) plus two separate digital inputs. The system operates independently or as a remote IP sensor for E‑2D/5D/16D systems and offers a user‑friendly web interface for configuration and monitoring worldwide—saving time and improving operational reliability.

In today’s digital environment, downtime is costly—precise environmental monitoring is essential. The ENVIROMUX® 1‑Wire system stands out for its flexibility: it supports up to 24 individual 1‑Wire sensors or up to 8 temperature/humidity/dew point sensors, with a maximum cable length of 183 m per RJ11 port. Consider a cold storage example: a sudden humidity increase caused by a leak could threaten perishable goods. The system detects this immediately and sends configurable alerts to a facility manager or via SNMP to the existing network management system. With two RJ11 ports for daisy‑chaining, two digital inputs, and optional PoE support, it offers versatility and easy installation. The unit can ping up to four IP devices and report non‑responses, ensuring higher availability and reduced downtime.

The advantages of ENVIROMUX® 1‑Wire are evident in real‑world scenarios, such as co‑location sites. The device mounts easily on a wall or DIN rail, connects to the network, and configured temperature or humidity thresholds trigger alarms automatically. For instance, humidity above 85 % due to leakage activates a “Smart Alert” that combines multiple conditions to minimize false alarms. One customer reported the system prevented water damage worth thousands of euros. Hot‑swappable sensors allow maintenance without downtime, and integration with Nagios and Zabbix is seamless. With an MTBF exceeding 500,000 hours and security protocols such as HTTPS, SSLv3, and AES‑256 encryption, it protects your infrastructure and data. Ideal for IT infrastructure, cold‑storage facilities, and unattended sites - the ENVIROMUX® 1‑Wire is your reliable monitoring solution.

Additional Features and Benefits

The ENVIROMUX® 1‑Wire monitors temperature, humidity, liquid, power, intrusion, and smoke. When thresholds are exceeded, it sends alerts via email, web interface, SNMP, or SMS. It can operate stand‑alone or as a remote sensor for E‑2D/5D/16D devices. It supports up to 24 1‑Wire sensors (temperature, humidity, dew point, digital inputs) and two separate digital inputs.
