Perseus Monitoring 140

Perseus Monitoring 140

The modern world of technology and infrastructure requires reliable monitoring solutions that are both flexible and powerful. The Perseus Monitoring 140 is an advanced device for environmental monitoring, specifically designed for professional use in technical rooms, data centers, warehouses, and other critical environments.

With its ability to integrate a variety of sensors and evaluate data from other devices via a LAN network, this device sets new standards in LAN monitoring. Whether in the pharmaceutical industry, telecommunications, or logistics, the Perseus Monitoring 140 offers a comprehensive solution for the remote monitoring requirements of modern companies.

Overview of the Perseus Monitoring 140

The Perseus Monitoring 140 is a versatile device designed to simplify sensor integration and analyze data in real time. With a capacity of up to 1000 variables, the device can monitor a wide range of environmental parameters such as temperature, humidity, voltage, current, or water ingress.

Thanks to its support for Modbus/RTU, SNMP Trap, and an open API (XML, Modbus/TCP, MQTT), it is ideal for companies wishing to seamlessly integrate their monitoring systems into existing infrastructures.

The device features four RJ11 ports for 1-Wire UNI sensors, an RS-485 port for Modbus/RTU sensors, and a special WLD port (Water Leak Detection) for water leak detection. In addition, the unique Meters API enables the acquisition and analysis of sensor data from other LAN devices, such as the STE2 R2 thermometer or SNMP-enabled UPS systems. This flexibility makes the Perseus Monitoring 140 an indispensable tool for monitoring critical infrastructures.

Main Features of the Perseus Monitoring 140

Connectivity and Sensor Support

• Ethernet Port (RJ45, 100BASE-T): The Perseus Monitoring 140 features an integrated web server, allowing easy configuration and monitoring via a browser interface.
• 4x RJ11 Ports: Up to two 1-Wire UNI sensors per port, measuring parameters such as temperature, humidity (indoor/outdoor), voltage, or current (0-30A or 4-20mA).
• RS-485 (Modbus/RTU): Enables integration of D3 sensors, such as power meters or air conditioning units.
• WLD Port: Supports a water leak detection cable with a total length of up to 185 meters.
• Digital Inputs and Outputs: Four digital inputs (DI) for dry contacts (e.g., smoke detectors, door sensors) and two digital outputs (DO) for controlling relays, such as for air conditioning or doors.

Data Processing and Analysis

The advanced Lua scripting functionality of the Perseus Monitoring 140 enables the creation of custom logic for data analysis. Companies can use scripts, calendars, or periodic schedules to define complex conditions for monitoring specific events.

For example, an alarm can be triggered if two out of three temperature sensors exceed a critical value. This flexibility makes the Perseus Monitoring 140 ideal for applications requiring precise and customizable monitoring.

Alarms and Notifications

The Perseus Monitoring 140 offers versatile alarm options that can be triggered both locally and over the network:

• Local Alarms: Relay outputs (DO) can be switched based on sensor data, e.g., to activate fans or alarm sirens.
• Network-Based Alarms: SNMP Trap, email notifications, or SMS/calls (via an external SMS gateway) immediately inform responsible personnel about critical events.
• Portal Notifications: When connected to the SensDesk Portal, additional functions such as device invalid alerts, PDF reports, and multi-year multigraphs can be used.

Open API and Integration

Thanks to the open API (SNMP, XML, Modbus/TCP, MQTT), the collected data can easily be integrated into existing SCADA or NMS systems. The Meters API allows the Perseus Monitoring 140 to read sensor data from other devices on the same network, facilitating the monitoring of complex environments. For example, the device can compare the temperature of its own sensor with that of an external STE2 R2 thermometer and additionally include data from an SNMP-enabled UPS.

Security Features

Security was a top priority in the development of the Perseus Monitoring 140:

• Radius – IEEE 802.1X: Supports secure authentication in the network.
• HTTPS with Client Certificate: Ensures encrypted communication.
• Admin and User Accounts: Allows access control for different user groups.
• IPv6 Support and SNMP v3: For modern and secure network environments.

Connection with the SensDesk Portal

Integration with the SensDesk Portal significantly extends the functionality of the Perseus Monitoring 140. The portal offers:

• Graphs and Multigraphs: Visualization of sensor data with historical trends.
• Virtual Sensors: Calculation of averages or other aggregated data.
• Device Failure Alerts: Notification if the device loses connection.
• PDF Reports: For audits and reporting in regulated industries.
• Multi-User Accounts: For teams with different access rights.

The SensDesk Portal is available as both a SaaS solution and on-premise, allowing companies to choose the deployment option that suits them best. For simple applications, the free HWg-cloud.com portal is available, offering basic features such as email alerts and simple graphs.

Typical Application Areas

The Perseus Monitoring 140 is suitable for a wide range of scenarios where precise environmental monitoring and rapid response times are required. Here are some of the most common use cases:

• Data Centers and Server Rooms: Monitoring temperature, humidity, and water ingress to protect expensive hardware.
• Pharmaceutical Warehouses: Ensuring regulatory compliance by monitoring temperature and humidity.
• Telecommunications Sites: Monitoring base stations and technical rooms for reliable operation.
• Warehouses with Cooling: Control of freezer and cold rooms with up to four temperature sensors directly connected to the Perseus Monitoring 140.
• Greenhouses: Monitoring temperature, humidity, and other environmental parameters to optimize plant growth.
• Industrial Facilities: Integration of sensors for current, voltage, or smoke detectors to monitor critical machinery.

A typical example is monitoring a cold storage room in a warehouse. The Perseus Monitoring 140 can connect four temperature sensors (up to 60 meters 1-Wire UNI) directly to monitor the temperature in freezers and refrigerators. Additionally, the device can monitor the battery status of an external UPS via SNMP using the Meters API.

An alarm can be configured to trigger if two out of five sensors exceed a threshold or are unavailable. These alarms can be sent to specific recipients according to an internal schedule to ensure a quick response.

Advantages of the Meters API

The Meters API is a unique feature of the Perseus product line. It enables the device to read sensor data from other devices on the same LAN network and use it for analysis or alarms. This is particularly useful in complex environments where multiple devices provide data. For example, the Perseus Monitoring 140 can compare the temperature of its own sensor with that of an external STE2 R2 thermometer and additionally include data from an SNMP-enabled UPS. This data aggregation enables more precise decisions and alarms based on multiple data sources.

Mobile Monitoring with the HWg Monitor App

The HWg Monitor App (available for Android and iOS) offers a convenient way to monitor all sensor data at a glance. The app can connect directly to the Perseus Monitoring 140 or via the SensDesk Portal. It displays all sensor values on one screen and is ideal for mobile monitoring or as a wall display in technical rooms. With the app, responsible personnel can check the status of their monitored environments anytime and anywhere.

The Perseus Monitoring 140 is a powerful and flexible solution for the remote monitoring requirements of modern companies. With its ability to integrate a variety of sensors, analyze data from other devices, and provide versatile alarm options, this device is ideal for critical applications in data centers, warehouses, telecommunications sites, and more.

Support for Lua scripting, SNMP Trap, Modbus/RTU, and the unique Meters API make the Perseus Monitoring 140 an indispensable tool for companies that value reliability, flexibility, and security. Integration with the SensDesk Portal further expands functionality, allowing companies to benefit from enhanced analysis and reporting options.
