Smart features making it perfect IoT gadget

Small, battery powered, recorder that monitors and records real-time data such as humidity, temperature, movement, light strength etc. Acquired data is stored in the internal memory in a form of a data-log (data with timestamps) and regularly sent by means of wireless (radio) communication to a cloud-based software to be at disposal of its user for further analysis.


  • Several adjustable data inputs enabling simultaneous connection of different types of sensors.
  • Monitors: voltage, current, magnetic field, humidity, UV, temperature, movement, shaking, Co-CO2, radiation etc.
  • Smart storage of recorded data in a smart data logs (data together with timestamp).
  • Powerful microprocessor unit enabling customer adjusted functionality.

Perfect IoT gadget

  • Battery powered, small in size makes it easy to be put on “strategic places”.
  • Powerful microprocessor unit enables software features adjusted to customer demands.
  • Available different types of radio communication modules using public (GPRS, LTE, Narrowband) or proprietary (LoRa, MBUS, WiFi…) networks.
  • Efficient and secure communication protocols.
  • Cloud based supporting SW enables full IoT system with reaction to critical data in real-time.

Practical applications

  • Environment monitoring applications (weather or pollution).
  • Designated data acquisition (counting events, R&D testing equipment such as remote tracking etc.)
