Overview
An easy-to-deploy, low-cost cellular monitoring station for long-term, reliable monitoring of indoor conditions in warehouses, cold storage facilities, data centers, museums, commercial and residential buildings, and more. This station includes an integrated HOBOnet Manager for easy deployment with wireless HOBOnet sensors. The station also features inputs for up to five of HOBO research-grade plug-and-play sensors. Configurable station-side alarms trigger immediate notifications of critical conditions, and the LI-COR Cloud (formerly HOBOlink) software platform makes it easy to view, access, analyze, and share data.
