Detects tremors
A sensitive MEMS sensor reads ground vibration 250 times per second. Sensitive enough to tell a passing truck apart from real shaking.
Early-stage hardware startup
How did your building move in the earthquake? We built a device that measures it.
SismoSmart plugs into a socket and mounts on the wall. It measures your building's motion continuously and notifies your phone when the shaking is serious. Its real job is the recording it keeps: when an engineer arrives, they can read how the building behaved at the time.

Data flow
Measurement starts at the device and ends on your phone.
The device measures, encrypts and sends. The app turns that into something readable: is the device alive, what was the last event, which way is your building trending.
- The wall-mounted MEMS sensor has a noise floor of 22 µg. Your phone sits around 2,000 µg. The gap is roughly a hundredfold.
- You can see your building's vibration data without handing over personal information.
- The device doesn't decide in the engineer's place. It gives the engineer better data.

Where we stand
There are things this device cannot do.
SismoSmart is still in its pilot phase. What it does is 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 of those stay where they are. We fill the gap in between.

How it works
Setup takes a few minutes. Everything after that is in the background.
Once the device is up, there is nothing left for you to do. It spends the first few days learning your building's normal vibration profile, and after that it can pick out what isn't normal.
- 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
For a few days the device just listens to your building's normal vibration. It learns what a passing truck does, what a windy day does. It can only spot the abnormal once it knows the normal.
- 04
It notifies you when shaking starts
When it detects serious vibration, a notification lands on your phone. If nearby devices saw the same shaking, the notification arrives marked as confirmed.
- 05
It records the event
The raw data from during and after the shaking is kept on the device and sent to the cloud. An engineer can read how the building responded from that recording.
- 06
More devices, better results
With several devices in one building you can see how the floors move relative to each other. With several in one neighborhood, the odds of a false alarm drop.
What it does
It quietly does several separate jobs at once.
Notifying you during an earthquake is only one of them. The valuable part is what happens before and after: it tracks the building's health for months, and it records what happened while the ground was moving.
Notifies your phone
When it detects shaking, a push notification goes out. It says what to do: drop, cover, hold on.
Tracks your building's health
Every building has a natural frequency. The device tracks that and the damping ratio over months. An unexpected shift there can be an early sign of structural trouble.
Reports after an earthquake
Peak acceleration, duration and how your building responded end up in a single report. The engineer has a starting point before they even arrive.
Reads temperature and humidity too
A building doesn't behave the same in winter as in summer. Without environmental data you can't tell that seasonal drift apart from real damage.
Stronger together
Every device in your neighborhood feeds the shared signal. As the count goes up, confirmation gets faster and false alarms get rarer.
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
A device in a few flats and one in the common area. We agree it with the building management and install it free for six months.
Campuses and factories
Facilities with more than one building. One device per building, all of them visible from a single dashboard.
University partnerships
We share data with earthquake engineering departments. Researchers get anonymized access and we get academic feedback.
FAQ
Frequently asked questions
If your question is here, so is the answer. If it isn't, write to info@sismosmart.com and we'll answer it. The full list lives on the FAQ page.
Will this device warn me before an earthquake?
We're talking seconds, not minutes. If the earthquake comes from a distance, the device can catch the fast-moving P wave and send a notification before the destructive S wave arrives. If the epicenter is close, that window shrinks to almost nothing. We don't market this as an early warning system, because it won't work for every earthquake.
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 do the opposite: how your building 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. The person who gets to call a building safe or unsafe is an engineer, not a device. What the device does is leave that engineer something solid 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 and no technician. It takes five minutes.
What happens during a power or internet outage?
If the internet goes, the device keeps measuring, saves the event to its own memory, and uploads it when the connection returns. If the power goes, the supercapacitor inside gives it 30 to 60 seconds of bridge power, which is enough to push the last event to the cloud. A longer outage shuts it down.
When does it go on sale?
Pilots start in summer 2026 and we're aiming for broad availability by the end of 2026. Certification and manufacturing could push that back. Sign up for the newsletter and you'll hear the firm date first.
