Product Description

The HOBO H21-USB Micro Station Data Logger is a weatherproof data logger for multi-channel monitoring of microclimates. This battery-powered station accepts up to five plug-and-play Smart Sensors and has a hinged door to make sensor installation simple and quick.

The Micro Station is equipped with a built-in USB port for fast, efficient data readout to a computer, and integrated mounting tabs for easy installation. The weatherproof IP66 enclosure ensures reliable operation in harsh outdoor environments.

The logger supports logging intervals from 1 second to 18 hours with 512 KB of nonvolatile flash memory. It operates on four AA batteries: alkaline batteries provide -20°C to +50°C operating range, while lithium batteries extend operation to -40°C to +70°C. Typical battery life is one year with up to five sensors at a 1-minute logging interval.

The H21-USB is compatible with HOBOware and HOBOware Pro software for logger setup and data analysis. Smart sensors are sold separately.
