MMW-005 Solid State Wind Sensor
__________________________________________________________________________________________

Introduction

1.
The MMW-005 is a solid state wind sensor type (Figure 1),
which uses a specialized chip to measure wind speed and wind
direction based on the temperature differences across the chip
surface. These temperature differences are processed by a
small microprocessor in the sensor, resulting in a serial signal
for the indication of wind direction and wind speed. The output
signal of the sensor is RS-422 and is standardized according to
NMEA-0183
