Overview
Measures and transmits temperature and relative humidity data wirelessly to mobile devices or Windows computers via Bluetooth technology.
This self-contained wireless data logger works with your mobile device or Windows computer and Onset's free HOBOconnect app so you can configure the logger and download data when within 100 feet of the logger, with no other dedicated equipment required. You can also view data in graphs, check the operational status of the logger, configure alarm notifications, and share data files.
Add the MX Gateway for remote access to your data in Onset's HOBOlink cloud software platform.

FAQs
The temperature sensor can measure temperatures ranging from -20° to 70°C (-4° to 158°F).
The accuracy varies depending on the temperature range:
±0.21°C from 0° to 50°C (±0.38°F from 32° to 122°F)
The resolution of the temperature sensor is 0.024°C at 25°C (0.04°F at 77°F).
The temperature sensor has a drift of less than 0.1°C per year (0.18°F per year).
The typical response time to reach 90% in air moving at 1 m/s (2.2 mph) is 7 minutes and 30 seconds.
The relative humidity sensor can measure humidity from 1% to 90% (non-condensing).
The accuracy of the relative humidity sensor is:
±2% from 20% to 80% (maximum of ±4.5% including hysteresis at 25°C or 77°F)
Below 20% and above 80%, the accuracy is ±6% typical
The resolution of the relative humidity sensor is 0.01%.
The relative humidity sensor has a typical drift of less than 1% per year.
The typical response time to reach 90% in airflow of 1 m/s (2.2 mph) is 20 seconds.
The logger operates within a temperature range of -20° to 70°C (-4° to 158°F) and 0 to 95% relative humidity (non-condensing).
The logger has a transmission range of approximately 30.5 meters (100 feet) line-of-sight.
The logger uses Bluetooth Low Energy (Bluetooth Smart) for wireless data transmission.
The logging rate can be set from 1 second to 18 hours.
The logging modes available are fixed interval (normal, statistics) or burst.
The memory modes are wrap when full or stop when full.
The start modes are immediate, push button, date & time, or next interval.
The stop modes are when memory is full, push button, date & time, or after a set logging period.
The time accuracy is ±1 minute per month at 25°C (77°F).
The battery life is typically 1 year with a logging interval of 1 minute. Faster logging intervals, entering burst logging mode, and remaining connected with the app will impact battery life. Excessive readouts, audible alarms, and paging also impact battery life.
The logger uses two AAA 1.5 V alkaline batteries, which are user-replaceable.
The logger has 128 KB of memory, which can store up to 84,650 measurements.
Downloading the full memory typically takes approximately 60 seconds, though it may take longer if the device is farther from the logger.
The dimensions are 3.66 x 8.48 x 2.29 cm (1.44 x 3.34 x 0.9 inches), and it weighs 56 g (1.98 oz).
The logger has an IP50 environmental rating.
