3Pcs Microwave Doppler X-Band Radar Sensor Wireless Module Motion Speed

Description: This HB100 Miniature Microwave Motion Sensor is a X-Band Bi-Static Doppler transceiver module. Its built-in Dielectric Resonator Oscillator (DRO) and a pair of Microstrip 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. Features: Great replacement for failing or faulty Doppler radar microwave motion sensor module Highly resistant to radio-frequency interference Detection range: Over 20 meters Output power: 5mW Dimension(L x W x T): Approx. 1.75 x 1.45 x 0.3 inch / 4.4 x 3.7 x 0.8cm Non-contact detection Independent of temperature, humidity, noise, airflow, dust, light, etc. suitable for harsh environments Strong resistance to RF interference Low cost & Low Power Consumption.
