HOBO Pendant MX loggers measure temperature (MX2201) or temperature/light (MX2202) in indoor and outdoor environments. Designed for durability, these compact, waterproof loggers can be used in numerous applications, including fresh and salt water. The loggers are Bluetooth® Low Energy-enabled for wireless communication with a mobile device. Using the HOBOmobile® app, you can easily configure the loggers, download logged data to your phone or tablet, or automatically upload the data to HOBOlink® for further analysis. You can also configure the loggers to calculate statistics, set up alarms to trip at specific thresholds, or enable burst logging in which data is logged at a faster interval when sensor readings are above or below certain limits.
