LSI LASTEM ToTEM™ Total Environmental Monitoring System

The LSI LASTEM ToTEM™ (ToTal Environmental Monitoring) system is an innovative family of compact environmental monitoring stations designed to provide highly accurate meteorological and environmental measurements in a single, integrated solution. Combining WMO-grade sensing technology, smart communications, and modular expandability, ToTEM delivers reliable environmental data for a wide range of industrial, research, infrastructure, and smart city applications.

Unlike traditional compact weather stations, the ToTEM platform has been developed to overcome the limitations often associated with all-in-one monitoring systems. Its advanced architecture integrates multiple environmental sensors while maintaining the accuracy typically expected from larger and more complex monitoring installations.

The ToTEM system can be configured to measure a comprehensive range of environmental parameters, including:

• Wind Speed and Wind Direction
• Ambient Temperature
• Relative Humidity
• Atmospheric Pressure
• Solar Radiation
• Rainfall
• Particulate Matter (PM)
• Black Globe Temperature
• Heat Stress Indices and Derived Meteorological Parameters

These measurements are delivered using professional-grade sensors designed to meet demanding monitoring requirements.

ToTEM offers flexible communication options to suit both fixed and remote installations, including:

• RS232 and RS485 serial communications
• Modbus RTU protocols
• LTE-M cellular connectivity with integrated eSIM
• LoRa wireless communications
• Analogue outputs (4-20 mA options available on selected models)

This flexibility allows seamless integration into existing monitoring networks, SCADA systems, cloud platforms and industrial control systems.
