Robomart 10.525GHz Microwave Motion Sensor Module

Miniature Microwave Motion Sensor is an X - Band Bi-Static Doppler transceiver module. Its built-in Dielectric Resonator Oscillator (DRO) and a pair of Micro strip patch antenna array, make it ideal for OEM usage in motion detection equipment. This module is ideally suitable for false alarms reduction in intruder detectors when work together with Passive Infrared (PIR) sensor. It can also be used for auto-door opening and vehicle speed measurement. Miniature microwave motion sensor is a common ingredient in security systems and automatic door openers, and can detect movements in a room, yard, or even on the other side of a wall. When the Enable pin is held high or left floating, the device takes brief, periodic, low-power Doppler radar measurements. The frequency of the Output pin's high/low signal oscillation corresponds to the speed of the motion. 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 microvolts (?V). A high gain low frequency amplifier is usually connected to the IF terminal in order to amplify the Doppler shift to a processable levelMiniature Microwave Motion Sensor is designed to meet the requirements of Federal Communications Commission (FCC) rules, Part 15, Section 15.245 (use within a building or to open building door). The noise voltages are measured from 10 Hz to 100 Hz at the output port, inside an anechoic chamber.
