IMPORTANT: HOBO data loggers require HOBOware software (USB interface cable included w/CD purchase). See compatible items below.

The award-winning HOBO Weather Station offers easy configuration and dependable research-grade measurements at a reasonable cost. The HOBO Weather Station records up to 15 channels of measurements, and a broad range of plug-and-play smart sensors are available for monitoring all kinds of environmental conditions - from temperature and humidity to soil moisture, wind speed/direction, rainfall, leaf wetness, solar radiation, and barometric pressure. Input adapters for 4-20mA, DC voltage, and pulses increase the range of possible measurements.

  • Accept Onset's wide range of plug-in smart sensors
  • Optional analog and pulse inputs for 3rd-party sensors
  • Battery-powered for up to a year - no solar panels required


 

CE Compliance

Onset products have been CE compliant for many years.  Recently the European Union changed the CE regulations, effective July 20, forcing Onset to either change the circuitry in some products, or choose to no longer list them as CE compliant. In most cases we offer CE compliant alternative products.

Rest assured Onset has placed a high priority on making all current products CE compliant before year-end. If you are not shipping this item to a EU country after July 20, please disregard this message.

This product is not currently CE compliant. If you are shipping to a EU country, Onset recommends using the CE compliant parts: U30-NRC or U30-NRC-SYS-A

This product has been discontinued.
