SpaceLogger W8 Wireless Overview

Like the SpaceLogger W10, the SpaceLogger W8 Wireless has been developed for economic logging of real-time wind speed and direction data when using Gill Instruments' anemometers with a single serial output and for full environmental data logging from the MetPak Weather Station.

SpaceLogger W8 Wireless is compatible with the following Gill Instruments' meteorological sensors:

These sensors may be set to output in the following compatible modes:
  • ASCII UV (or UVW) continuous
  • ASCII Polar continuous (default setting)
  • ASCII Tunnel continuous
  • MODBUS RTU (MaxiMet GMX range)

Data is stored on a removable SD or SDHC memory card. Current and historic data files may be accessed wirelessly using the SpaceLogger Real-time Communicator Software.

Data is sampled at 1Hz from the connected sensor. Each data record is date and time-stamped when it is stored. A new file (.CSV) is generated for each day's worth of data.

Raw wind & weather data is processed by the logger to calculate 10 minute averaged values with min and max readings during that period. This data set is recorded every 10 minutes in a separate daily .CSV file.

A Wi-Fi wireless local area network (WLAN) is required for remote access to the data stored on the logger. If this is temporarily unavailable, data may be downloaded directly from the SD card to a PC if it is removed from the SpaceLogger. Includes WPS functionality.

Configuration of the SpaceLogger for the WLAN is via a simple set-up file written to the SD card.

The SpaceLogger Launcher Software may connect to multiple loggers within the same WLAN at any time.

The SpaceLogger W8 Wireless may be enabled for FTP'ing of live wind & weather data to the website to provide access to the real-time data remotely.

The SpaceLogger W8 Wireless logger requires RS232 input; this may be direct from the sensor or via a WS-15A Display Unit for local display of live weather data. When long cable runs dictate use of RS485, a WS-15A Display or RS485 to RS232 converter enables connection to the logger.

SD Card Data Capacity

With WindLogger, the logging interval may be selected from the WindSonic settings of 4, 2 or 1 reading per second, or set to one reading every 1 to 60 seconds. With a logging interval of one reading per second, using a 2GByte card, WindLogger will store up to 19 months worth of WindSonic data.

When logging from a WindSonic sensor, each data reading comprises up to 41 bytes. The following table gives the approximate capacity of various sized memory cards, depending on the logging interval selected, assuming a WindSonic sensor is connected:

Logging Interval (Readings per time interval)
Memory Card Size 4 per sec 2 per sec 1 per sec 1 per 2 sec 1 per 5 sec 1 per 10 sec
1 GB 75 days 150 days 300 days 600 days >4 years >8 years
2 GB 150 days 300 days 600 days >3 years >8 years >16 years

When logging from aMetPak weather station, each data set comprises at least 75 bytes.  The following table gives the approximate capacity of various sized memory cards, depending on the logging interval selected, assuming a MetPak is connected:

  MetPak II
Logging Interval (Readings per time interval)
Memory Card Size 1 per sec 1 per 2 sec 1 per 10 sec
1 GB >150 days >300 days 4.5 years
2 GB >300 days >600 days 9 years
