    The device is a Plug’n Play concept which is used to measure and analyze the indoor climate at home and at workplace.

    It also measure, visualizes and also analyze indoor climate in a room and at a building.  This concept is compromised by data measurement device, a server and website with APP client for mobile units they are IOS/Mobile. 

    This device also gives a accurate information for temperature, humidity it as a new feature on the consumer market which measures the level of CO2.

    The device gives the measurements that are uploaded to the server every 5 minutes through client’s own Wifi or the internet. 

    In the meanwhile the server also automatically retrieves local weather forecasts, energy measurements etc. from public and commercial supplier’s servers. 

    The IC-Meter GPRS/ WiFi is a generic and globally focused product which is based on facts.

    Some of the facts are: 

    1. Laws of thermo-dynamics are valid universally.

    2. Weather forecast data are also standardized widely and globally.

    3. The preferred communication platform of the world’s population is internet.

    The KRM Smoke Detector analyze indoor climate and indoor energy conditions by use of quality sensors and advanced algorithms. There is no need for consultants nor for the questionnaire forms.

    The device also retrieves automatically local weather forecasts for any location on the earth. By analyzing and comparing the climate of the room with the local weather forecast the device delivers key values for air turnover, minutes per day with the ventilation, daily production of water vapor as well as for function “Any one home right now?”. The energy usage can be remote observed and diagnosed and distributed between buildings envelope, air turnover and base load hot water as well as the heat contribution of the sun can be estimated by combined with an external energy meter example IC-Meter “digital oil meter” or data from an electricity plant.


    1. It can be used in VDS certification.

    2. It can be used in patented single tube air sampling system.

    3. It can be used in contamination display in % and signaling at 100%.

    4. It can be used in electronic air flow control.

    5. It can be used in externally operable reset button in the housing. 

    6. It can be used in remote rest option through terminals.

    7. It can be used in long service life for low communication.

    8. It can be used in Modbus interface (KRM-2-MOD only).
