Temperature and humidity measurement with wireless sensor FTM 20 TF

The new AFRISO FTM 20 TF temperature sensor, which does not require batteries and is low maintenance, measures ambient temperature and humidity in rooms at regular intervals. Any significant changes in sensor data are immediately transmitted to the optional AFRISOhome gateway, the essential component of a modern building management system. It is perfect for setting up a smart home system in apartments, multi-family houses, or office buildings. The data can be used as input for controlling actuators, such as radiator actuators or EnOcean wireless exhaust fans.

The new AFRISO FTM 20 TF temperature sensor measures the ambient temperature and the humidity in rooms. Its sensor data is transmitted to a gateway and can be used to directly control room temperature controllers or radiator actuators.

The energy required to send a wireless telegram is generated by means of an integrated photovoltaic cell. The integrated, solar-operated energy storage module allows for several days of operation even in total darkness. In permanently dark environments (such as basements or warehouses) it is also possible to use a button cell battery. 

A double-sided adhesive strip allows for extremely easy mounting of the compact housing to walls or furniture. It is possible to plug on an enclosed metal plate which serves as a base for placing the sensor on a shelf, a window sill or a sideboard. 

FTM 20 TF works in conjunction with, for examples, the AFRISO wireless actuators AVD 20-D and AVD 30 or with the AFRISOhome gateway. Products from other vendors can also be connected to this gateway. The user can configure a whole range of fully customisable, extensible applications which can be controlled via smartphones or tablets.
