LE 8 Band ee Motion Sensor Module Ped Manual v1.02 nnn wey HB Series of microwave motion sensor module are X-Band Bi Static DRO Doppler transceiver front-end module. These modules are designed for movement detection, like intruder alarms, occupancy modules and other innovative ideas. Oscillator The module consists of Dielectric Resonator Oscillator (DROP, microwave mixer and patch antenna (see Diagram A). This Application Note highlights some important points when designing-in HB100 module.
HB100 X Band Li Motion Sensor Module User Manual v1.02 The module operates at +3 Vdc for Continuous wave (CW) operation (see Annex 1). The module can be powered by +5V low duty cycle pulsed trains in order to reduce its power consumption, Sample & Hold circuit at the IF output is required for pulse operation (see Annex 2). a naan The transmit frequency and power of the module is set by factory. There is no user adjustable part in {his device.
_HB100 Bang v1.02 Doppler shift Doppler shift output from IF terminal when movement is detected. The magnitude of the Doppler Shift is proportional to reflection of transmitted energy and is in the range of micro volts (uV). A high gain low frequency amplifier is usually connected to the IF terminal in order to amplify the Doppler shift to a processable level (see Annex 1). Frequency of Doppler shift is proportional to velocity of motion. Typical human walking generates Doppler shift below 100 Hz.

CRETE The module has been fully tested to specifications. Upon opening, tighten or loosen the chassis will cause performance deterioration. The module is an electrostatic sensitive device (ESTES. Precautions shall be observed for handling and assembly.
