A time to celebrate: Cindy Man opens a bottle of champagne to celebrate the commissioning of her wind-power monitor at Ngong Ping's automatic weather station.  Electricity is supplied to the station with a wind-power generator.

Cindy Man, an engineering graduate from the Electrical & Mechanical Services Department, never dreamed that one of her inventions could help monitor Hong Kong's sometimes unpredictable weather.

But her new electronic device now helps the Hong Kong Observatory monitor the operation of wind-powered automatic weather stations in remote areas.

The device, put into operation at Ngong Ping on Lantau today, can tell the Observatory whether sufficient electrical energy is generated to support the operation of the station in an instant.
