201 Readout with Optional Logging to USB Flash Drive

101-D Combined Self-Powered Wind Speed and Wind Direction Sensor

Yagi directional antenna

Power transducer

The 101-D sensor paired with the 201 logger with Yagi antenna provides reception up to 600 feet.  The sensor is self-powered and requires no batteries for operation.  At 5 MPH it is "on the air" broadcasting new data every second.  The 201 base unit with optional data logging stores data on a USB flash drive.  Data is saved as an excel spreadsheet which can be opened for analysis on an PC.  Adding a power transducer allows data logging of wind turbine power.  This enables determination of wind turbine power curves, logs total energy etc.
