Detects tremors
The current design targets an ADXL355-class MEMS sensor and 250 Hz three-axis sampling. Bench and pilot evidence are still required for detection and performance claims.
Early-stage hardware startup
We're building a device that measures how your building moves in an earthquake.
SismoSmart is a wall-mounted device we're developing to measure and record building motion. It is still pre-launch: detection, notification, connectivity and performance will be validated in pilots. The goal is to leave a qualified engineer a useful motion record after shaking.

Data flow
Measurement starts at the device and ends on your phone.
In the design, measurement happens on the device and data is sent securely when there is a connection. Device security, reporting and long-term trend views will be validated in pilots.
- The current design targets an ADXL355-class sensor, 250 Hz three-axis sampling and a documented noise objective; final performance awaits a frozen bill of materials and bench evidence.
- You can see your building's vibration data without handing over personal information.
- The device makes no decisions; it collects data for the engineer to review.

Where we stand
There are things this device cannot do.
SismoSmart is still in its pilot phase. It aims to record what happens inside your building and turn that into data you can look at afterwards. We are not competing with national alerting systems or with the structural inspection that follows an earthquake; both stay where they are. We are trying to fill the gap between them.

How it works
Setup takes a few minutes. The rest runs in the background.
In pilots we are testing whether the device can learn a building's normal vibration profile and separate unusual motion from everyday noise. False positives and missed events are still possible.
- 01
Mount it on a wall
Pick a stable indoor wall. The adhesive strip comes pre-applied, and there are screw holes if you would rather fix it properly.
- 02
Pair from the app
The SismoSmart app finds the device over Bluetooth. You enter your Wi-Fi password once, and that's it.
- 03
It learns the building
In pilots we are trying to build a baseline from ordinary vibration such as traffic and wind. We won't call the method reliable until it has field evidence.
- 04
It notifies you when shaking starts
The design aims to issue a notification after on-device detection. Notification timing and multi-device confirmation will be tested in pilots.
- 05
It records the event
In the design, an event is stored on the device and uploaded to the cloud when there is a connection. We won't present this as a working feature until pilots have tested the full path.
- 06
More than one device
Several devices may give useful evidence on motion between floors and on matching events. Accuracy and the effect on false alarms still need pilot data.
What it does
It quietly does several separate jobs at once.
The product is being designed around event recording and longer-term building-motion evidence. Notification, structural-health interpretation and other features are not yet validated. They are goals we are working toward, not guaranteed outcomes.
Notifies your phone
How notification will behave still has to be validated in pilots. SismoSmart is not an emergency service or an official warning system; follow official alerts and emergency guidance.
Tracks your building's health
A change in measured vibration characteristics may give engineers additional evidence over time. It is not a diagnosis and cannot determine whether a building is safe.
Reports after an earthquake
The planned post-event report aims to summarize measured motion for qualified review. Its contents and interpretation will be validated in pilots.
Reads temperature and humidity too
Environmental sensing is designed to help engineers separate seasonal effects from other changes. It does not by itself identify damage.
Matching across devices
Matching events across several devices is a design goal. Its effect on confirmation time and false alarms has not yet been shown in pilot evidence.
Pilot path
We want to try this in a handful of real buildings first.
Before we scale the product we want to see it in the field. Feedback from the first pilots will decide what the finished device looks like. For now we're talking to three groups.
Apartments
Pilot device count, duration, ownership and commercial terms are agreed case by case. This page does not commit to free hardware or a fixed pilot term.
Campuses and factories
Facilities with more than one building. One device per building, all of them visible from a single dashboard.
University partnerships
Research access would require explicit pilot terms, privacy controls and a separate data-sharing agreement. It is not the default data flow.
FAQ
Frequently asked questions
If your question isn't here, write to info@sismosmart.com and we'll answer it. The full list is on the FAQ page.
Will this device warn me before an earthquake?
No. SismoSmart is not an earthquake early-warning service and does not promise advance warning. Pilot work may evaluate low-latency notifications after on-device detection, but official alerts remain the source for emergency warnings.
How is this different from Google's earthquake alerts?
Google uses the accelerometer in people's phones. It's free, it's already on every handset, and it works well. But what it measures is the source of the earthquake, not your building. We measure your building instead: how it vibrates, how that changes with the season, what state it's in after an earthquake. A phone can't answer those questions.
Can a single device tell me my building is safe?
It can't. An engineer decides whether a building is safe. The device leaves that engineer solid data to work from.
Is installation difficult?
You plug the USB-C cable into a socket, stick the device to the wall with the adhesive on the back, and pair it from the app. No drill or technician is needed, and setup takes a few minutes.
What happens during a power or internet outage?
The current design targets local buffering during network loss and a short supercapacitor bridge during power loss. Exact duration and end-to-end upload behavior will be confirmed through hardware and pilot testing.
When does it go on sale?
There is no firm public sale date. SismoSmart remains pre-launch; pilot evidence, hardware readiness, certification and manufacturing will determine the schedule. Subscribe for confirmed updates.
