Simple design of a low cost K-band motion sensor pcb design plus software where the movement detection shall be done with a uPC. For example PIC or ATMEL uPC. All information of the 24GHz sensor available, the doppler output is in frequency range of a few Hz to few KHz depending on speed of object. Basically the design shall include 1 or 2 low noise operational amplifier(s), designed as filter and amplifier. The output will be directly for the input of the A/D converter of the uPC. The software shall check if a object moves within the microwave beam and shall drive a transistor or relay to give alarm. The uPC shall be able to set the sensitivity of the motion sensor to certain levels and the timing of the output for the transistor. All shall run at 5 Volts. to supply a programmed uPC is essential, the pcb can be done by me if all files are available. Support for opams and questions about doppler operation and frequencies is available.
