MX1104 Temp/RH/Light Data Logger

Sale priceR 6,021.12
SKU: MX1104



The HOBO MX1104 multi-channel data logger measures and transmits temperature, relative humidity, and light intensity data wirelessly. Additionally, it features an external analog input to attach a variety of other sensors.

This self-contained, Bluetooth-enabled wireless data logger allows users to conveniently access data using their mobile devices or a Windows computer. With Onset's free HOBOconnect app available for iOS, users can access the logger's data at any time within a 100-foot range via Bluetooth Low Energy (BLE) technology. The logger offers a suite of functionalities: it allows for configuration, data readout, graphical data viewing, operational status checks of loggers, alarm notifications configuration, and data file sharing, all without the need for dedicated equipment other than a mobile device or laptop.

For those seeking remote data access, the MX Gateway can be added, providing access to the recorded data in Onset’s cloud-based HOBOlink® software.

This versatile tool ensures efficient data logging and remote monitoring capabilities, all streamlined for user convenience.
