The HOBOnet Wireless Temperature and Relative Humidity Sensor provides a cost-effective and scalable solution for web-enabled monitoring of air temperature and humidity. HOBOnet Wireless Sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX station, or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset’s innovative cloud-based software platform.
The HOBO MX2302 is a weatherproof data logger with external temperature and relative humidity sensors. Leveraging Bluetooth Low Energy, the logger enables easy, fast setup and data download directly from your mobile device or Windows computer with Onset's free HOBOconnect app. The MX2302 provides high-accuracy measurements in harsh outdoor environments.

The HOBO RX3000, Onset’s most flexible remote data logging station, provides instant access to site-specific environmental data anywhere, anytime via the internet. The station combines the versatility and sensor quality of more expensive systems, an onboard LCD display, and the convenience of plug-and-play operation. The RX3000 is a configurable system (see "Configure System" tab below).
The RX3000 station is the basic component of the cost-effective and scalable HOBOnet Field Monitoring System for crop management, environmental research, and greenhouse operations.
The HOBO RX3000 Weather Station Starter Kit provides instant access to site-specific air temperature, relative humidity, and wind speed/direction data anywhere, anytime on your desktop or mobile device.
The RX3000 accepts up to 10 plug-and-play Smart Sensors. Just plug in your sensor and it’s automatically recognized – no programming, wiring, or calibration necessary.
This weather station kit includes a one-year cellular data plan plus cloud-based data access through HOBOlink – for 24/7 access to your data and the ability to verify RX3000 system status, set up and manage alarm notifications, and schedule automated delivery of data.
Rugged and compact, the redesigned HOBO USB Micro Station is a weatherproof data logger for multi-channel monitoring of microclimates. Starting at just $220, 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.
Looking for a cellular option? The MicroRX Station offers integrated solar panel or battery-power for affordable remote data offload via 4G cellular.
Interested in water level and flow monitoring? The MicroRX Water Level Station combines the MicroRX Station with Onset’s own water level sensor and pre-programmed water flow formulas.
The HOBO Weather Station Starter Kit combines our most rugged data logging weather station with out-of-the-box convenience.
The U30/NRC accepts up to 10 plug-and-play Smart Sensors. Just plug in your sensor and it’s automatically recognized – no programming, wiring or calibration necessary. With this kit you can measure temperature, relative humidity, wind speed/direction. Simply select the HOBO Weather Station starter system and your choice of either a 2-Meter or 3-Meter Tripod Kit and go!
Software ordered separately. Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis.
The Temperature/Relative Humidity Smart Sensor is designed to work with all Onset data loggers that accept smart sensors. All sensor parameters are stored inside the smart sensor, which automatically communicates configuration data information to the logger without any programming, calibration, or extensive user setup.
