GRILLO PULSE

Sensitive and Smart Earthquake Sensor

Detect earthquakes or building vibrations and see the data instantly.

High performance accelerometer

Grillo Pulse is perfect for seismic imaging, structural health monitoring, and other vibration monitoring applications. It has powered Grillo’s Mexico EEW since 2017 and proven more effective than sensor networks 100x the cost.

Plug and Play

The Grillo Pulse comes pre-loaded with firmware that connects to the Grillo Cloud, providing low-latency streaming of unprocessed triaxial accelerations. Simply install the sensor, connect to local wifi, and you’re set.

Grillo Cloud

Grillo Pulse connects by wifi to Grillo Cloud where you can download data, monitor sensor status, locations and more. With the EEW cloud plan you can even visualize a real-time stream.


from grillo.data.df import get_df_from_records

# Specify start and end dates in UTC
start_date_utc = '2018-02-16 23:39:00'
end_date_utc = '2018-02-16 23:43:00'

# Get records for the specified dates
records_df = get_df_from_records(
    data_client.get_filtered_records(
        start_date_utc,
        end_date_utc
        )
    )
     

Analyze historic or streaming data

Download your data from the dashboard, or using our python library. If you require real-time data we can setup a streaming service for you (with an EEW cloud plan).

GRILLO Pulse

We manage your data. You focus on the work.

Grillo Pulse sensors are programmed to send all their unprocessed data to the cloud every second. When you purchase a sensor you need to also select a Cloud Plan to access the data.
