KMY24 Datasheet | Infineon

.. Microwave Motion Sensor KMY 24 Description The KMY 24 is a microwave rader motion sensor based on the Doppler effect. It transmits a low energy microwave radiation at 2.45 GHz which is reflected by objects. If the object is moving relative to the sensor, a Doppler shift occurs. The shifted wave is mixed with the original wave in two mixers, resulting in two output voltage signals. The phase shift between these two signals is negative or positive depending on whether the target is approaching or receding from the detector.

Solder pads must not be perforated, as this will damage, EHA07260 and may destroy the multilayer PC Board. 2. Regulations on the use of High frequency devices. The use of high frequency devices is regulated in most countries and certain frequencies can be subject to restrictions. The use of the KMY 24 should be clarified with the respective authorities in each country to ensure pliance with the prevalent legislation. Data Sheet 1999-04-01 .. KMY...
