Sens-it is a company with the core business of measuring and registering the indoor climate in spaces in buildings. This is done based on the latest technology of Internet of Things (IoT). This technology makes it possible to create the large infrastructure (ie no power, internet, wifi, 4G, etc.). We use sensors that are easy to install and when the indoor climate is clear. After the moment of placing, the first measurement in real time in the dashboard of that moment was built up in 5 minutes by means of stairs. This dashboard is made available for the customer. We rent the security including the dashboard and data management, so no major investment is necessary. This product is ideal for a quick analysis, but can also be used for a permanent measurement. After analysis of the measurement data, in consultation with the client, a tailored advice can be made to improve the indoor climate.
