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.

Clinton Global Initiative

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.

“To improve earthquake preparedness and response in the region, Grillo is committing to deploy their sensor technology to Puerto Rico, to strengthen seismic monitoring on the island. They will build the foundation for an earthquake early warning system throughout the Caribbean region.”
