Outdoor transmitter

• Wireless Data transmitted at 868 MHz
• Wireless Transmission at 868 MHz : 100 metres (in open field)

PC connection

• Computer connection included
• Delivered with setup CD-ROM (in French, English and German) and 2 metres of cable for the base-computer link
• Data is gathered by the computer, from which it is possible to use the data and design graphs
• Possible storage of 1750 sets of data, a set of data is a recording of information at that point in time from all sensors.
• The recording regularity for a set of data can be set from once every 1 minute through to once every 24hrs. For example if you recorded a set of data once every hour you would get 24 sets of data per day to view for all weather sensors and barometric pressure etc. So 1750 sets divided by 24 would give you approximately 73 days worth of data
• Minimum system requirement for use of this Heavy Weather software is :
• Operating system : Windows 98 or above
• Processor : Pentium 166 MHz or above
• RAM : 32 MB of RAM or above
• Hard-disk : 20 MB free space
• CD Rom drive

Frequencies

• The transmission is at 868 MHz, the recording is every 4 to 6 seconds (if the wind is more than 10 m/s) or every 128 seconds (if the wind is less than 10 m/s) or 10 minutes if the station fails to receive any data after 5 attempts in a row (all outdoor data readings will display “---“ except for the rain value)

Measurement
• Of the Station ( L x W x D) = 255 x 154 x 30 mm
• Of the thermo/hygro transmitter ( L x W x H) = 62 x 57 x 156 mm
• Of the rain meter ( D x H) = 131 x 151 mm
• Of the anemometer ( L x W x H) = 250 x 276 x 145 mm
