K-LC2 is a 2 x 4 patch Doppler module with an asymmetrical beam for lowcost short distance applications. Its typical applications are movement sensors in the security and presence detection domain. In building automation this module may be an alternative for infrared PIR or AIR systems thanks to its outstanding performance/cost ratio.
FSK is possible thanks to the unique RFbeam oscillator design. This allows to use this lowcost module even in ranging applications. Powerful starter kits (ST100 and ST200) with signal conditioning and visualization on the PC’s are available.
