Gravity: Digital Microwave Sensor (Motion Detection)

Gravity: Digital Microwave Sensor (Motion Detection)The microwave sensor applies the Doppler effect to detect moving objects using microwaves. This differs from the method used by a regular infrared (IR) sensor as microwave is sensitive to a variety of objects that are microwave reflective, and its sensor readings are not affected by the ambient temperature. This type of sensor is widely used in industrial, transportation and civil applications such as measuring vehicle speed, liquid levels, automatic

Temperature effect on sensitivity(%RO/°C): 0

If you're feeling really advanced

It's the upgrade to the L3G4200 (see this app note on what to look for if upgrading an existing design to the L3GD20) with three full axes of sensing

and many connector placements are already taken care of
