Description: Microwave motion sensor is a microwave moving object detector based on the principle of radar. Unlike ordinary infrared detectors, microwave sensors detect the motion of objects by detecting the microwaves reflected by objects, and the detection object will not be limited to the human body, but many other things. Microwave sensors are not affected by ambient temperature, long detection distance, high sensitivity, and are widely used in industrial, traffic and civil devices, such as vehicle speed measurement, automatic doors, induction lights, reversing radar and so on. Due to the universality of microwave sensor detection objects, in actual life applications, another sensor will be paired to do targeted detection. Such as microwave sensor + infrared pyroelectric sensor, can effectively determine whether someone is passing by, will not be by sunlight, by the color of clothing, and will not react to other objects. Feature: 1. Non-contact detection, microwave directivity is very good, speed is equal to the speed of light 2. Not affected by temperature, humidity, noise, airflow, dust, light, etc., suitable for harsh environment 3. Strong resistance to RF interference 4. Small output power, no harm to the human body 5. The detection distance is long, supporting the detection of non-living objects Parameter: Operating voltage: 5V Operating current (CW) : 60mA max., 37mA typical Size: 61.2x61.2mm Emission parameter: Detection distance: 2-16m continuously adjustable (minimum range 2m, maximum range 16m) Transmission frequency: 10.525 GHz Frequency setting accuracy: 3MHz Output power (min.) : 13dBm EIRP Harmonic emission: Less than -10dBm Average current (5% DC) : 2mA typ. Pulse width (Min.) : 5uSec Load cycle (Min.) : 1% Receiving parameter: Sensitivity (10dB S ratio)3Hz to 80Hz Bandwidth: -86dBm 3Hz to 80Hz bandwidth clutter 10uV Antenna gain: 8dBi Vertical plane 3dB beamwidth: 36 degrees Horizontal 3dB beamwidth: 72 degrees pin description Material: PC+metal Color: as shown Due to different product batches, the appearance may be different, which does not affect use.
