HOBO® MX1105 Data Logger
4-Channel Analog Data Logger
The HOBO MX1105 multi-channel data logger, with four-channel
inputs, measures and transmits data wirelessly from a variety of
sensors to your mobile device via Bluetooth Low Energy (BLE)
technology.
This self-contained wireless data logger lets you use your mobile
device and Onset’s free HOBOconnect app to access data, at any
time, over a 100-foot range via Bluetooth Low Energy (BLE)
technology. You can configure the logger, read out data, view data
in graphs, check the operational status of loggers, configure alarm
notifications, and share data files – all with no dedicated equipment
beyond a mobile device. And if used with the new MX Gateway, you
can remotely access your data in Onset’s cloudbased HOBOlink® software. The MX1105 is ideal for energy audits,
building commissioning studies, equipment scheduling, and more.
