A multi-channel data logger records measurements from more than one sensor or input channel on a shared time base. This makes it possible to compare related parameters—such as temperature, relative humidity, pressure, airflow, current, or voltage—without managing a separate logger for every measurement.

The MX1104 includes built-in temperature, relative humidity, and light-intensity sensors, along with one external analog input. The MX1105 does not include those built-in environmental sensors; instead, it provides four external analog input channels. Both models support compatible Self-Describing sensors and other supported analog sensors.

Self-Describing sensors store their configuration information inside the sensor. When a compatible sensor is connected to an MX1104 or MX1105, HOBOconnect automatically detects it and applies the appropriate configuration information. Compatible non-Self-Describing analog sensors can also be used, but they require manual selection and configuration in the app.

When you are within Bluetooth range, you can use the free HOBOconnect app on a compatible mobile device or Windows computer to configure the logger, view current conditions, download data, and create graphs. An internet connection is not required for local Bluetooth communication. For cloud access, add an MX Data Plan and push data through HOBOconnect or use an MX Gateway to transfer data automatically to LI-COR Cloud over Wi-Fi or Ethernet.
