A team of Dutch scientists wants to use the crowd instead, by turning umbrellas into mini weather-monitoring stations. Every time it rains, smart umbrellas would use sensors to detect falling drops, and then use Bluetooth to send a report to a smartphone app. As people walk around with umbrellas throughout a city during a storm, each app would send in data to a central system where meteorologists could use it to come up with better predictions.
