The wind speed alarm is configurable as either a high or a low alarm and to avoid false alarm events, there are adjustable hold off and hold on times. The 40 character easy to read display shows wind speed in a choice of measurement units and wind direction in degrees, as a wind arrow and as cardinal points.

Case Study


Richard Paul Russell Ltd. was delighted to offer a cost effective 'plug and play' solution to Phoenix Model Flying Club. Founded 30 years ago with over 200 members, they required ground level highly accurate wind data so members can judge safe limits to fly. An essential part of the requirement was for members to be able to view the data remotely so they can avoid unnecessary trips to the club when high winds are present.

Richard Paul Russell Ltd. delivered a cost-effective solution that exceeded the clients brief, meeting all their "must-haves" with additional desirable functionality well within budget. Key elements of the system included a WeatherFile Connection Unit (WCU) that gathers data directly from the sensor that is sent over the local WiFi network to the WeatherFile website. This data can be viewed over the public internet with any connected device from any location. Additional email alert functionality enables club members to receive notifications directly to their inbox when wind limits are exceeded.

The system was self-installed on time within budget and to specification, delivering highly accurate live wind speed and direction readings through a Gill WindSonic 1 sensor connected directly to WeatherFile. Email alerts and long term data capture provide a complete solution that far exceeds the clients' expectations.

Choose your sensor based on the parameters you want to measure.
