Overview
Ideal for energy audits, building commissioning studies, equipment scheduling, and more, this self-contained, Bluetooth-enabled, wireless data logger lets you use your mobile device or Windows computer and Onset's free HOBOconnect app to access data, at any time, when within 100 feet of the logger. Configure the logger, read out data, view data in graphs, check the operational status of loggers, configure alarm notifications, and share data files - with no dedicated equipment beyond a mobile device or laptop.
Add the MX Gateway, for remote access to your data in Onset's HOBOlink cloud software platform.
