This project required weather data to be monitored at a remote air strip in a valley, which was then sent via the mobile phone network back to Sydney so the owner could monitor weather conditions before flying out to this remote location. The only Next G phone signal was located almost 2km away through dense bush on the side of a hill. The solution required a three part approach;
- A high quality weather station capable of transmitting long distances out of the box if possible rather that high cost aftermarket 2.4 gig wireless hardware that was difficult to configure and maintain.
- Highly reliable Next G Telemetry solution able to provide near real time weather data via web, mobile phone with the ability to provide Weather Alerts via SMS and Email
- Due to the remote location the solution needed to be solar powered that was cost effective, had a small footprint and could withstand severe weather conditions.
Part One the Weather Station
Currently the only out of the box high quality weather station capable of transmitting long distances over 2.4gig was the Rain Wise MK-II which transmits up to 1.6km line of sight out of the box. Due to the dense bush between the weather station and receiver the optional Flat panel directional and Omni-directional base antennas were fitted. In testing we were able to transmit 12km line of site and maintained 85% plus signal strength. Similar results were recorded over 2km through dense bush at the air strip site.
Part Two the Telemetry Communications
This was done via the RainWise Teledata Next G RTU. The Teledata Next G RTU plugs into the RainWise 3300 logger / receiver providing the transmission of weather station data along with virtual sensors that provided, Dew Point, Sigma Theta winds stats and Live Fire Danger Index which is useful when you air strip is located in remote bushland. Weather Station data can be viewed and or downloaded via the RainWise Teledata server;
With the RainWise 3300 logger Telemetry mode enabled the power consumption is reduced by up to 50% along with the low power usage of the RainWise Teledata RTU (12VDC 65mA) a small 20watt solar panel and 20 amp hour battery was all that was required to run both units allowing for near real data 24 x 7 . This system also allowed for SMS enquiry to current weather conditions via SMS
SMS phone number 0458 501 336
Wn.0: (Current weather stats)
Cb.0: (Telemetry box temp & solar system)
Sigma.0: (Current Sigma Theta wind stats)
SMS commands are not case sensitive and 0 is the number zero
The remote station can also be configured with sensor alarms and alarm groups. When an alarm is triggered eg, 90mm day rain, Very High Fire Danger, 80km wind from the West, etc the remote station will send a SMS and or Email Weather Alert to the mobile numbers and emails in that alarm group.
