Monitoring
using wireless sensors
Geomatic SIA offers the latest technologies related to the monitoring of buildings and structures. This includes monitoring using wireless sensors.
Wireless sensors provide much more in-depth knowledge of the state of the sites being monitored during (e.g.) construction; when
piles are drilled, sensors make it possible to see in real time what impact this action has on adjacent buildings, so that preventive
decisions can be made and actions can be taken to help builders avoid additional costs associated with cracks in adjacent buildings.
Sensors can be installed, and measurements of the condition of various different buildings and structures can be obtained. Most often, sensors are used to monitor:
- Buildings and structures;
- Bridges;
- Railway infrastructure;
- Tanks, pipelines.

Currently, SIA Geomatic is the official cooperation partner of the US company www.resensys.com in Latvia.
We offer Resensys wireless sensors and SenSpot™ geophones, SeniMax™ gateway/base stations, and SenScope™ software.
SenSpot™ sensors and geophones are wireless monitoring devices that transfer data about the state of properties being monitored to the SeniMax™ data gateway (base station) that transmits data to a secure cloud/server. Data can be accessed from anywhere in the world via Wi-Fi internet.
The power source is a lithium-ion battery. The sensors are among the world’s most energy-efficient sensors, with a service life of up to 10 years without the need to replace the battery. The sensors do not require maintenance or calibration throughout their operation. They operate over a wide temperature range, from -40°C to +65°C.
Inclination sensors

Inclination sensors are used to measure the tilting of structures. They can be installed on a vertical structure, such as a wall, column or façade, and measure the inclination from the vertical line; these sensors can also be installed on horizontal floors to measuring their tilt.
SenScope™ software

Resensys SenScope™ is designed for real-time monitoring and data analysis based on Resensys SenSpot™ sensor measurements. SenScope™ is capable of processing substantial amounts of sensor data, creating schedules, and performing data analysis.
The software is also designed for configuring sensors and for the control of properties under monitoring. The following options are also present:
- Real-time communication capability with Resensys SenSpot™ sensors and Resensys SeniMax;
- Visualisation, comparison and analysis of data;
- Data analysis (e.g. effects of temperature on cracks in the walls of the building, or on expansion or reduction);
- It is possible to set averages and maximum limits, and to generate and send alarms and alerts on a 24/7 basis, in the form of e-mail and SMS, if the thresholds are exceeded;
- Visualisation and archiving of historical data.
