Automatic, accurate, affordable ambient conditions monitoring

Kaltiot offers affordable ambient conditions monitoring for construction sites as part of our full set of construction monitoring services.

The basic monitoring service tracks air temperature and humidity (RH). Concrete humidity, air pressure, and air dust content can also be tracked.

The solution uses 100% wireless sensors which can be taped, glued, or screwed in place. The sensors are affordable and the battery life will last for the entire project duration, up to 2 years. As soon as they’re installed, the sensors start sending data to the project online cloud dashboard where it can be viewed from anywhere, at any time.

Sensors are typically installed when the external structure of the building (walls and roof) are in place, and the windows and doors are either installed or covered to enable interior climate control.

Compared to manual sensors, the sensors enable more detailed and more accurate historical data, real-time checking of measurements from anywhere, and comparison of data between different points in the building.

For example, if the sensor in one apartment unit in a 50-unit building shows a drastically lower temperature, perhaps a door or window was left open in that unit. A worker can be sent to close the door so the unit will dry properly and to cut the heating bill.

What types of projects is this for?

Kaltiot Smart Tracker makes sense for sites that would use 10 or more sensors. The larger the project, the more useful automated monitoring is. There is no upper limit to the number of sensors.

In addition, companies that might later want to start using other features of Kaltiot Smart Tracker like dust, air pressure, equipment location tracking and worker tracker can start with ambient condition monitoring.

How are the sensors installed?

Sensors are typically installed when the site needs interior climate control to ensure the proper temperature and humidity range for structural dryness and interior work, such as flooring and tile installation.

Sensors can be attached to a wall surface that will remain unfinished (such as behind a permanent cabinet) or taped to a ceiling light fixture location, so they do not need to be moved until interior work is completed.

Data collection begins as soon as the sensor location is marked in the control panel. Automatic data collection continues until end of project.

The sensors can be returned to Kaltiot at the end of the project or used for the next project depending on customer needs.



Optimize heating to cut expenses

Heating costs are an enormous expense on large construction projects and can add up to 10000€ or more per month.

Real-time sensors let you detect and fix issues like a door left open somewhere or a leak in the building envelope, or insufficient airflow in certain spaces. This cuts wasted energy from heat escaping the building. Better optimized heating also means a shorter total drying time which also cuts heating expenses.

Predict and speed up concrete drying

With an accurate historical record of the temperature and humidity conditions in each space of a concrete structure, you can more accurately predict when interior work can begin, and where. This helps avoid delays due to insufficiently cured concrete.

In addition, by keeping optimal conditions throughout the entire building, the building will dry faster and more evenly so interior work can begin sooner.


Ensure the right conditions for high quality

Temperature and humidity can vary significantly between units on the same site. Central, automatic monitoring of every unit is more accurate than typical manual measurements done in just a few spots in the building. The right conditions are essential for a high-quality end result and minimized risk of mold and structural dampness.


Reliable data

Typical absolute accuracy:

  • Relative humidity (RH): ±2 % (20…80 % relative humidity at 25 °C)
  • Temperature: ±0,2 °C @ 5…60 °C
  • Air pressure: ±1 hPa, relative accuracy ±0,06 hPa
  • Particulates PM2.5: ±10 μg/m3
  • Particulates PM10: ±25 μg/m3

Multiple sensors are available for different needs. Sensor technical certifications are available. Read more about our technology here. The information on this page is a guideline and device specs may change, confirm specs with our sales team.


One system that grows with your needs

Smart Tracker is expandable. It can be used to monitor any number of construction sites at once. The data can be imported into other tools or BIM software your company uses. The Smart Tracker system can handle many other key monitoring and tracking needs for construction companies within the same system.
