Overview

The HOBO MX2202 waterproof temperature/light level logger leverages the power of Bluetooth Low Energy (BLE) to deliver accurate temperature and light-level measurements straight to your mobile device with Onset's free HOBOconnect app. Designed for durability, this compact waterproof logger is ideal for measuring temperature in streams, lakes, oceans, and soil environments. Data collection in the field has never been easier!

Add the MX Gateway for remote access to your data in Onset's cloud-based HOBOlink software (indoor deployments).

Mounting Requirements: It is very important that the logger housing does not get distorted when mounted. When mounting these loggers to any non-flat surface, such as rebar or posts, we recommend using the Mounting Boot (BOOT-MX2201-2201). This boot is also useful for mounting loggers so they can be easily removed for service.

Frequently Asked Questions

Can I download data from MX2200 Series loggers deployed in water?

No, the MX2200 Series need to be taken out of the water to download the data.

Do I need an optical shuttle to download data from the MX2200?

No, you need to have a mobile device such as a phone or tablet that runs iOS or Android operating systems and that have Bluetooth Low Energy (Bluetooth 4.0 or above) in order to download the data.

Is an event recorded in the data file when the logger is submersed or removed from the water?

With the MX2203 & MX2204, the user has the option while configuring the loggers to use the Bluetooth Off Water Detect. The logger will not advertise when the presence of water is detected. Once the logger is removed from the water, advertising will automatically turn on, thereby not requiring you to push a button (or use a magnet) to wake up the logger when you need to connect to it. This option preserves some battery power. Note: The logger will check for the presence of water every 15 seconds when this is option is selected.

Do the new MX2200 Series water loggers replace the existing Pendant and TidbiT water loggers?

No, we will continue to support the TidbiT, Pendant, and Water Temp Pro optical products although we encourage folks to take a look at the new features of the MX2200 Series.

Can I use HOBOware software to graph, analyze and export the data?

You have the ability to share a .HOBO file via email, or use HOBOlink.com to then open up the file in HOBOware to do additional data analysis like combining graphs and analyzing your data further. Note that HOBOmobile can also directly output a .XLSX & .CSV file format if you choose to work in Excel
