  • Easy mounting via wall bracket


Determination of the ambient temperature and air humidity at a defined location.


The temperature sensor FTM T transmits the current ambient temperature via the integrated EnOcean wireless module to the AFRISOhome gateway. The temperature and humidity sensor FTM TF also transmits the value of the current air humidity.
Based on the event message, the AFRISOhome gateway can trigger measures. The energy required to send a wireless telegram is generated by means of the integrated photovoltaic cell. An optional battery can be used for application in darker rooms. The ambient temperature can be readjusted via the single room temperature controller CosiTherm® Wireless in order to keep the room temperature from rising or falling. The AFRISOhome gateway transmits alarm messages and changes in temperature and/or humidity via WLAN or LAN to the person in charge (for example, to the owner, the facility manager, the janitor or other configured contacts); the message includes information on which temperature sensor has signalled the change.
The AFRISOhome gateway in conjunction with additional AFRISO smart home products with EnOcean wireless technology allows the user to configure a whole range of fully customisable, extensible applications.
