IIRIS salt therapy device

Our customer is well-established professional halogenerator manufacturer. They needed a consumer device that can be used at homes. We designed electronics hardware and created embedded software for a device with touch screen user interface for salt therapy sessions at home. Device allows to select different levels of salt-aerosol concentration. It has various working modes.

Smart wild bird feeder

Battery powered wild bird feeder detects wild bird visits and takes high quality photos of birds. All photos are instantly published to web server over Wifi and can be seen via mobile apps. 

Cable connection tester

Industrial cable connection tester measures cable connections’ resistance and correctness. LED indicators allow easily to identify faulty connections.

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.
