The HOBO MX2300 Series Data Loggers record and transmit temperature and/or relative humidity (RH) in outdoor or indoor environments. These Bluetooth Low Energy-enabled loggers are designed for wireless communication with a mobile device. Using the HOBOmobile app, you can easily configure the logger, read it out and view data on your phone or tablet, or export the data for further analysis.
The logger can calculate minimum, maximum, average, and standard deviation statistics and be configured to indicate alarms at thresholds you specify. The logger also supports burst logging in which data is logged at a faster interval when sensor readings are above or below certain limits. The Temp and Temp/RH models have internal sensors while the External Temp/RH, External Temp, and 2x External Temp include built-in external sensors, offering a wide range of solutions for monitoring temperature and RH in numerous applications.

Application Notes and White Papers
This product can be used in the following applications:
Here's how some of our customers used this product.
Monitoring Temperature and Humidity in a Greenhouse
The Background: Our customer is a small plant nursery that wants to keep track of the temperature and humidity levels inside their greenhouse.
The Problem: The customer seeks a quick and easy solution. They intend to permanently mount the instruments and want to make sure it’s easy to access the data.
The Solution: We recommended a HOBO MX2300 series data logger. The MX2300 is compatible with either integral or external temperature and humidity sensors and can wirelessly transmit data to a mobile device via Bluetooth. The unit is easy to set up and has a long battery life.
University Study on Snow Melt
The Background: Our customer is a university conducting a long term study to determine snow melt during the summer. They seek a number of data loggers with which to compile the data.
The Problem: The study involves covering large piles of snow with wood chips to insulate them, then monitoring temperatures at different depths in the snow pack. They are also monitoring ambient conditions such as temperature, wind, humidity, etc. and correlating all the data to try to predict the expected snow melt.
The Solution: We recommended HOBO MX2300 Series Data Loggers. The MX series accurately records low temperatures and transmits values wirelessly to a mobile device via Bluetooth Low Energy. Using the HOBOmobile app, the logger can be easily set-up. This represents a great way to gather the data needed for this study.
