Our Standard Moisture Sensor can measure relative humidity in walls and floors.

It is a passive and super thin sensor (like a sticky label), which makes it affordable. The components in the system are...

The Sensors



Used for scanning the sensor values.

For Sweden we have an exclusive reseller – Preventum – where equipment for quality assured repairs according to Sluta Riv’s rules, are provided.

Here are some typical scenarios where our sensors are used, but there are many, many more application areas.

You have purchased a building

…and want to assure that there are no moisture problems when the contractor delivers the building. Further, you want to check if there are any problems present prior to the expiration of the warranty. If you have installed our sensors, you will be able to measure if there are any problems with moisture before signing off the take over of your investment.

You are renting out apartments

…and there is a moisture damage in one of the bathrooms. If the Standard Moisture Sensor is installed, you can determine the magnitude of the damage, isolate it and repair the needed parts only, thus saving money.

You provide solutions for repair

…of moisture risk areas (bathrooms, kitchens, etc). You can increase the confidence in your installation by making it measurable and thus be able to visualize the quality of your installation.

Frequently asked questions

Are they simple to install?

Yes, the sensors are self-adhesive and you simply place them at a location where you want to measure moisture. You can find the instructions here.

How does the sensor work?

The sensor is based on a polyimide which is used within the electronics industry. It is a known material with known properties. It is very durable but has a critical flaw for many applications: it can absorb up to 2% water, which is a property we make use of. With the help of two printed capacitor plates and a coil we are able to measure the moisture content in the polyimide. This is done with our moisture scanner, which scans a frequency span and measures the response from the sensor. This response varies with the moisture content in the polyimide and is automatically translated into a moisture level value to the user.

How do you know where each sensor is installed?

The sensor is passive and its only purpose is to balance in moisture level with its surroundings in order to determine said moisture level. To localize the sensor and connect the measured value to a specific sensor we have developed an app where you easily can see where sensors are installed on a drawing of the measurable object. Before measuring you choose the sensor you are going to measure, and the result is saved to the chosen sensor. The value is also uploaded to InviSense Cloud for compilation and overview of the results.

How long does the sensor last?

The sensor is not limited by any battery time and the tests we have conducted doesn’t show any signs of aging. We haven’t seen any signs that the sensor wouldn’t last until you remove it.

Is it possible to get similar measurements with existing technology?

Yes, with traditional methods, which often use destructive sampling. This is the very thing we want to help our customers avoid.

Where do I buy the sensor?

We have a reseller TBD that handles the sales in Sweden. Please contact them. If you are from outside Sweden, call InviSense. +46 (0) 13101035 or send us an email to info@invisense.se. We speak Swedish and English!

How has the sensor been developed?

Our system is based on 10 years of research at Linköping University. The product was then developed by RISE Acreo and the founders of InviSense for about 5 years to get a functional and commercially attractive product. The results are good and we continue to develop the sensors to make them even better and to introduce new functions.

What does it mean that the sensor is passive?

It means that it isn’t limited by any battery time, doesn’t emit any radiation, can be extremely thin (less than 0.1mm) and has to be measured by InviSense moisture scanner where the sensor is located.

Does it have any limitations?

Yes, the reading done with the scanner is inductive, which means that it’s disturbed by metal. It’s thereby not possible to install the sensor behind or too close to metal.

Is it possible to see trends over time?

Yes, with the help of our user friendly InviSense Cloud all measurement data is saved and connected to each sensor. This means that it’s possible to see how a single sensor is affected. This could mean that new knowledge is created over time and with that it would be possible to make decisions regarding material choices suitable for different cardinal directions, applications and climate change.

Where is it suitable to install a sensor?

Where you want to measure moisture faster, more precise and simpler than with today’s instruments.

What is the primary application?

  • To have a quantitative check of the moisture level in the walls or floors of your building at inspections. You will get a number that will tell you if you have problems or not at your final inspection, two-year inspection and five-year inspection of your building. That way you are able to notice damage in time, and the fault can be corrected by the responsible party.
  • Having sensors in your building, you can quickly determine whether it’s damaged or not and the extent of the damage. You can then spend the time determining the cause of the damage and decide which corrective actions that should be conducted without tearing down too much.
  • If you also install sensors in a repaired construction you will be able to follow up if the fault is corrected.

What is the best thing about the sensor?

It measures moisture in the locations it’s placed. As an example, when the sensor is placed behind the sealing layer in a bathroom no moisture in the outer layers is considered in the measurement. We measure moisture where it counts, giving a relevant result without destructive sampling.
