Data Logger

4-Channel Analog Data Logger

Four channel inputs to measure and transmit data wirelessly from chosen sensors to your mobile device or Windows laptop via Bluetooth technology

HOBO 4-Channel Analog Data Logger

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 our 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.

Purchase an MX Data Plan to get more out of your data and access it from anywhere using the LI-COR Cloud software platform (formerly HOBOlink)! You can also purchase the MX Gateway station, which automatically offloads your logger’s data via Bluetooth and sends it to LI-COR Cloud.
