Internet of Things (IoT) Applications

STE2 is ideal for IoT applications and provides data transfer via Ethernet or WiFi. The SensDesk Cloud portal provides a quick view of the recorded data (up to 3 months) which can also be viewed on the SensDesk mobile application. Data can be sent via email, custom software or third-party Cloud applications using TCP and SNMP protocols. IoT PDMS software allows the data to be converted to Excel format for further analysis. Using SNMP support, STE2 logged data can be accessed via third-party IoT portals with data recorded in real-time and timestamped.
