Grillo Pulse Features
Our advanced seismic seismometer comes with these powerful capabilities
Solar & Battery Ready
Built-in solar input and battery charging allow you to connect an external solar panel and battery for continuous operation in remote locations.
LTE & Wi-Fi Connectivity
LTE cellular and Wi-Fi for reliable data transmission. Hardware-ready for Starlink connectivity when carrier support becomes 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
Everything included for off-grid operation with dual sensors - no need for digitizer or additional computing module.
Integrations
Configured to transmit directly to your seismic data acquisition system (Earthworm, SeisComP, Python, or Grillo Cloud).
Rapid Setup
No need for additional infrastructure - deploy with the IP68 weatherproof case and solar panel for true off-grid operation.

Real-World Application
See how our technology is making a difference
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.
