| Microwave Motion Sensor Description The KMY 10 is a microwave rader motion sensor based on the Doppler effect. It transmits a low energy microwave radiation at 9.35 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, resulting in an output voltage. Features * * * * * * High sensitivity Low power consumption High reliability Small size Light weight Low cost Marking KMY 10 (or SMX-11)) Ordering Code License No. Special Package KMY 10 Typ KMY 10 Q62702-R309 Germany: Switzerland: Austria: BZT B129549H BAKOM 92.1340.H.P GZ 104 091-ZB/96 1) Previous type designation SMX-1. Pin Configuration 1 2 3 - VS (GND) VD (output voltage) + VS 5V Voltage Regulator - o/p + Notes: 1. The adjustment screw located on the top EHA07119 Dual OP-Amp 123 face of the sensor housing is used to set the oscillator frequency. This adjustment is made and secured during production and to ensure the correct operation of the device it must not be tampered with! 2. Only the pads marked 1; 2; 3, are predetermined solder pads and only these pads should be used to connect the device. Soldering or otherwise interfering with any other parts of the AF-circuit board will immediately invalidate any warranty on the device! 3. The KMY 10 is classified as an Electrostatic Discharge Sensitive Device. Handling precautions for such devices must be adhered to! 4. 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 10 should be clarified with the respective authorities in each country to ensure compliance with the prevalent legislation.
