Grillo One
Grillo One is a strong-motion seismic sensor with a three-axis MEMS accelerometer. It connects by Ethernet or Wi-Fi and is powered through its USB-C port. Its hardware and software are open source; it is the same device used in the OpenEEW project.
At a glance
| Sensor | Three-axis MEMS accelerometer |
| Channels | HNZ, HNN, HNE at 125 samples per second |
| Connectivity | Ethernet, with Wi-Fi (2.4 GHz) if no Ethernet cable is connected at start-up |
| Power | USB-C, 5 V. USB-C is the only power input. |
| Timing | Network time (NTP) |
| Status lights | Three colour lights: Network, Sensor, and Data. See Status lights. |
| Firmware | Updated over the air from Grillo Cloud. Latest version: 1.0.1. See Firmware. |
| Managed in | Grillo Cloud |
Grillo One has no geophone, GNSS, battery, or cellular modem. For those, see Grillo Pulse.
Setup steps
- Claim the sensor in Grillo Cloud with its Device ID.
- Connect and install it.
- Verify that it is online.
Claim it before or soon after you connect it. A Grillo One sends health reports as soon as it is online, but it only starts sending seismic data once it has been claimed and has received its station code from Grillo Cloud.
Device ID
The Device ID is 12 uppercase hexadecimal characters, for example A0B1C2D3E4F5. It is printed on the sensor's label. Record it before you mount the sensor.
