W-SYS-FR   W-SYS-FR - HOBOnode Wireless Frost Alarm Starter System -

 

The HOBOnode Wireless Frost Alarm System, which combines a wireless temperature sensor, receiver, and free software (web download) provides a simple, cost-effective way to monitor frost & ice conditions. The system can wirelessly transmit air temperature readings to a PC, and provide audible and visual alarm notifications via cell phone text messaging and email when frost conditions occur. The wireless frost alarm system also makes it easy for you to view current temperature readings, as well as temperature trends over time.

Temperature

HOBOnode Receiver

    Transmission range - HOBOnodes to receiver 300m  range with clear line-of-sight. Any obstructions such as vegetation ro walls will reduce range significantally.
    Wireless Data Standard - IEEE 802.15.4, in the 2.4 GHz ISM band - Click here for local RF Regulation Compliance
    Environmental rating - NEMA 6P, IP68; (transmitter end)
    Operating range -40° to +50°C (-40° to 122°F)
    Receiver communication to PC - 1.8m  USB cable (extend with optional extension cables up to 80 feet)
    Max. Number of HOBOnodes and Repeaters - 50
    Receiver Battery Life: 3 yrs typical
    Receiver Power: USB powered with battery backup to retain network setup if PC is turned off. (Note that no data is stored in the reciever.)
    Dimensions: 16.5 x 5 cm (6.5" x 2")

HOBOnode Wireless Temperature Sensor

    Measurement Range: -40° to 100°C (-40° to 212°F)
    Accuracy - 0.22°C from 0 to 50°C (0.4°F from 32° to 122°F) - Note: For accurate temperatures in sunlight we recommend the use of our solar radiation shield. (RS3)
    Resolution - 0.025° at 25°C (0.045°F at 77°F)
    Response time - 3 minutes in air moving 1m/s; 30 seconds in water
    Sample rate -1 reading per minute
    Battery life - 1 yr typical w/o charging; 3 yrs typical w/ solar charging
    Size -16.5cm x 5cm; 3.7m cable to sensor
    Memory - None in HOBOnodes; requires HOBOnode Viewer to be running for data storage.
    Transmission range - HOBOnodes to receiver or repeater: 300m  range with clear line-of-sight. Any obstructions such as vegetation ro walls will reduce range significantally.
    Wireless Data Standard - IEEE 802.15.4, 2.4 GHz ISM band (license free worldwide) - Click here for local RF Regulation Compliance
    Environmental rating - HOBOnodes: NEMA 6P, IP68; temperature sensor probe is rated for 1-year immersion in freshwater = 50° C (122° F)
    Operating range- standard range: -20° to +50°C (-4° to 122°F) with optional lithium batteries: -40° to +50°C (-40° to 122°F)
    Setup/Installation:
        recommend 8 x 1-1/4", schedule 40 PVC pipe for mounting (purchase through local building supply store)
        for windy locations we also recommend our Guy Wire Kit (M-GWK) and ½" Stake Kit (M-SKA)
        note that the HOBOnodes should not be mounted on or near metal surfaces.
