Detailed Description

Driver for the EagleTree Systems Airspeed Sensor.

Has only been tested with V3 of the sensor hardware.

Notes: Connect directly to TWOG/Tiny I2C port. Multiple sensors can be chained together. Sensor should be in the proprietary mode (default) and not in 3rd party mode.

Sensor module wire assignments: Red wire: 5V White wire: Ground Yellow wire: SDA Brown wire: SCL
