Smart Bird Feeder

Machine vision is used to identify birds presence on the image and to identify birds species.

Air pressure monitor for construction sites

All measurement data is sent to server-based application over GSM. Web-based user interface allows to get overview of device measurements. Device can be set up conveniently via mobile phone

Trackers for logistics sector

Compact trackers report their location on predefined time intervals over GSM network. Battery powered trackers have optimized power consumption logic, which allows them to have several weeks long lifetime. Web-based user interface allows to see trackers route on a map.
