Structural Monitoring
Know what shaking reached your structure, and how strong it was.
Evidence when it matters
After an earthquake, engineers and facility teams need to know what each structure actually experienced, not what the regional estimate says.
On Grillo Cloud's Structural plan, each Grillo Pulse measures all the time and keeps the last 60 seconds in memory. When shaking crosses its threshold, it uploads that buffer and keeps recording until the shaking stops. Grillo Cloud records each upload as a trigger, with its peak ground acceleration, peak ground velocity, and dominant frequency.
Because sensors upload only when something happens, they use far less mobile data than continuous recording.
Grillo sensors have been deployed in schools, offices, and apartment buildings across Mexico City, one of the world's most seismically active cities, and the approach has been cited in Science magazine.
What you get
Triggered recording
Set a project-wide threshold, or one per sensor, from 1 to 2000 mg. Each recording keeps up to 60 seconds from before the threshold was crossed.
Peaks and waveforms
Horizontal and per-axis PGA, vertical PGV from the calibrated geophone, dominant frequency, and the waveform on every channel.
Email alerts
Choose an alert level, separate from the recording threshold, and up to 25 recipients. Grillo emails an alert within seconds, then a summary when the shaking ends.
Data API
Feed triggers and sensor health into your building-management system, SCADA, or reports through the read-only API.
Remote sensor management
Check each sensor's status, signal, and power, and update its firmware over the air, without a site visit.
Cellular or Ethernet
Pulse Cellular needs no building network. Pulse Ethernet connects to a wired port where you have one.
Use cases
Schools & public buildings
A record of the shaking each building experienced, ready for your engineers' post-event assessment.
High-rise residential & commercial
Sensors on several floors show how shaking changed through the structure.
Critical facilities
Hospitals, data centers, and emergency facilities that need to keep operating after a seismic event.
Bridges & dams
Record the shaking at structures where a failure would have the greatest downstream consequences.

Grillo is not a life-safety system. Recordings support, but do not replace, a professional assessment of whether a structure is safe. Email alerts can be delayed by networks and email providers. Read the Structural plan documentation.
