dWISE

Posted on by Pietro Robertazzi

What it does

Automatic monitoring, management, storage, and transmission of data collected from digital sensors (MODBUS RTU) for structural, geotechnical, and environmental monitoring, such
as inclinometers, temperature sensors, multi-parameter probes, hydrometers, etc. It is a wireless data acquisition system that, together with mGateway, provides a versatile and autonomous Early Warning system, ideal for short, medium, and long-term monitoring.

Strengths

– Versatile (structural, geotechnical and environmental monitoring);
– Ease of installation and use;
– Internal battery (3.6 V) and external (12 V) power supply;
– Multi-connectivity: Digimesh® / LORAWAN ®;
– Expandability/Modularity: up to 16 MODBUS sensors
– RTU (point and/or distributed monitoring);
– Integrated Diagnostics (network diagnostics, power supply, temperature, memory);
– Automatic sending of acquired data to mGateway;
– Integrated local alarms (on ON/OFF output);
– Great autonomy 2 years (typical, with one sensor and measurements every 60 minutes);
