Onset has introduced one of their top outdoor environmental monitoring solutions with the release of the U30 weather station. Application requirements can now be accurately met with easy configuration of the HOBO U30-NRC. The weather station offers up to 15 channels to gather environmental data which can be proficiently analyzed by uploading to HOBOware Pro software.
The supported measurements are Barometric Pressure, Leaf Wetness, Light Intensity, PAR, Pulse Input, Rainfall , Relative Humidity, Soil Moisture, Solar Radiation, Temperature, Wind Speed & Direction, 4-20mA, and Voltage Input.
Specifications
Normal operating range: -20°C to 40°C (-4°F to 104°F) Extended operating range: -40 to 60°C (-40 to 140°F) - see "Rechargeable Battery service Life" for impact of operations in Extended Operating Range. Sensor Inputs: 5 standard; option to expand to 10 Smart Sensor compatibility: Compatible with most Onset smart sensors, except for the S-BPA, S-TMA and S-THA Data channels: Maximum of 15 (some sensors use more than one data channel) Alarm output relay: Can be configured to be activated, deactivated or pulsed on user-defined sensor alarms. The relay can be configured as normally open or normally closed, and is rated for 30 V and 1 amp max. Expansion slot: One expansion slot is available for factory-installed expansion port. Local communication: Full Speed USB via USB mini-B connector Size: 17.8 H x 11.7 D x 19.3 W cm (7.0 H x 4 .6 D x 7.6 W inches) Weight: 2 kg (4 lbs 10 oz)
Materials: Outer enclosure: ABS blend with stainless steel hinge pins and bronze inserts Inner enclosure: Polycarbonate with bronze inserts U-Bolts: Steel with zinc dichromate finish Gaskets: Silicone rubber Cable entry channel: EPDM rubber Cable entry bars: Aluminum with ABS plastic thumb screws
Data storage memory: Nonvolatile flash data storage, 512K bytes local storage Memory modes: Stop when full, wrap around when full Operational indicators: Up to six (depending upon options) status lights provide basic diagnostics Logging interval: 1 second to 18 hours, user-specified interval Battery type: 4 Volt, 4.5 AHr or 10 AHr, Rechargeable sealed lead-acid Rechargeable battery service life: Typical 3–5 years depending upon conditions of use. Operation within the extended operating range (but outside the normal range) will reduce battery service life. Time accuracy: 0 to 2 seconds for the first data point and ±5 seconds per week at 25°C (77°F) Environmental rating: Weatherproof enclosure, tested to NEMA 6.
