Grillo Pulse

The Grillo Pulse is Grillo's professional-grade seismic sensor designed for remote and outdoor deployments. Featuring global cellular connectivity, solar power support, and GPS timing, it's built for locations where infrastructure is limited or unreliable.

It combines an ultra-low noise MEMS accelerometer with a sensitive 4.5Hz geophone, providing 4 channels of seismic data capable of capturing everything from microseismic events to strong local earthquakes.

Grillo Pulse
