The microwave motion sensor is a microwave moving object detector designed by the principle of radar. Different from ordinary infrared detectors, microwave sensors detect the movement of objects by detecting the microwaves reflected by the object. The detection object will not be limited to the human body, but there are many other things.Microwave sensors are not affected by ambient temperature, have a long detection range and high sensitivity. They are widely used in industrial, transportation and civil installations, such as vehicle speed measurement, automatic doors, induction lights, reversing radar, etc.Due to the universality of microwave sensors to detect objects, in actual life applications, another sensor will be used for targeted detection. for example, a microwave sensor + an infrared pyroelectric sensor can effectively determine whether someone is passing by, and it will not be interfered by sunlight or the color of clothing, and will not react to other objects.Product Features:Compared with other detection methods, this detection has the following advantages:Non-contact detection;Not affected by temperature, humidity, noise, airflow, dust, light, etc., suitable for harsh environments;Strong anti-radio frequency interference ability;The output power is small, which is not harmful to the human body;Long detection distance;Support the detection of non-living objects;The directionality of microwaves is very good, and the speed is equal to the speed of light;Technical specificationsWorking voltage: 5V0.25VWorking current (CW): 60mA (Max), 37mA (Typical)Interface type: Gravity 3-Pin interfaceTransmission parameters:Detection distance: 2-16m continuously adjustable (minimum range 2m, maximum range 16m)Transmit frequency: 10.525 GHzFrequency setting accuracy: 3MHzOutput power (minimum): 13dBm EIRPHarmonic emission:Less than -10dBmAverage current (5%DC): 2mA typ.Pulse width (Min): 5uSecDuty cycle (Min): 1%Receive parameters:Sensitivity (10dB S ratio) 3Hz to 80Hz Bandwidth: -86dBm3Hz to 80Hz bandwidth clutter 10uVAntenna gain: 8dBiVertical 3dB beam width: 36 degreesHorizontal 3dB beam width: 72 degreesColour:BlackMaterial:PCBSize:48.5x63mmPackage Contents:1 * Microwave sensor module1 * Gravity 3-pin cableOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
