Grillo Pulse Features
Our advanced seismic seismometer comes with these powerful capabilities
Off-grid Ready
Pulse runs from a single 12 V DC input. For remote sites, power it from a solar charge controller and battery system that supplies 12 V DC.
Cellular or Ethernet
Choose the cellular model (LTE) where there is mobile coverage, or the Ethernet model where a wired network is available.
Dual Sensing Technology
Geophone with pole-zero compensation extending the period to 2s (0.5 Hz) for improved detection of distant seismic events, paired with low-noise triaxial MEMS accelerometer for strong motion detection.
All-in-one Solution
Geophone, accelerometer, digitizer and communications in one weatherproof unit - no separate digitizer or computer needed.
Integrations
Configured to transmit directly to your seismic data acquisition system (Earthworm, SeisComP, Python, or Grillo Cloud).
Rapid Setup
Mount the IP68 weatherproof case and connect 12 V DC. For off-grid sites, add a solar charge controller and battery.

Caribbean Earthquake Early Warning System
As announced by President Clinton, Grillo is deploying sensor technology to Puerto Rico to strengthen seismic monitoring on the island and build the foundation for an earthquake early warning system throughout the Caribbean region. This initiative will improve earthquake preparedness and response across the region, providing crucial early warnings to vulnerable communities.
