This short video showcases some preliminary tests with a really interesting anemometer/wind sensor from modern device. This little sensor uses a technique called “hot wire” which involves heating an element to a constant temperature and measuring the electrical power that is required to maintain the heated element at temperature as the wind changes. With wind variance the sensor produces voltage/values. These values are sent through the serial port into grasshopper via the generic serial read component from firefly. Once the values are pipped into grasshopper they alter a series of relationships that inflates a 3-dimensional balloon.
