Transmission
433 MHz wireless or cable-based transmission 100 metres in open field
Transmission distance by cable : 10 metres (however an extra 10 metres can be added)
Frequencies
For 433 MHz transmission :
- if the wind speed is greater than 10 m/s, every 32 seconds
- if the wind is less than 10 m/s, every 128 seconds
- Or every 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) If the transmission is by cable, every 8 seconds
PC connection
Computer connection included Delivered with setup CD-ROM (in French, English and German) and one 2 metre cable for linking the base station and the computer (USB) Operating system : from Windows 98 to Vista Data is gathered by the computer, which can be used to create graphs or to export it Storage capacity of 175 sets of data
