10.525GHz Microwave Sensor 2-16M Doppler Radar For Ardunio HB100 pc66

Description: Description 10.525GHz Microwave Radar Sensor Microwave Motion Sensor Module 2-16M For Ardunio HB100 Description: The microwave motion sensor is a microwave moving object detector designed using Doppler radar principle. Unlike ordinary infrared detectors, microwave sensors detect the motion of an object by detecting microwaves reflected from the object. The detection object will not be limited to the human body, and there are many other things. The microwave sensor is not affected by the ambient temperature, has a long detection range and high sensitivity, and is widely used in industrial, transportation and civil devices such as vehicle speed, automatic doors, sensor lights, and parking sensors. Because of the universality of microwave sensor detection objects, in actual life applications, it will be matched with another sensor for targeted detection. Such as microwave sensor + infrared pyroelectric sensor, can effectively determine whether someone passed, will not be the sun, was disturbed by the color of clothing, will not respond to other objects. Features: - Non-contact detection - It is not affected by temperature, humidity, noise, airflow, dust, light, etc., and is suitable for harsh environments - Strong anti-radio interference capability - The output power is small, which is not harmful to the human body - Far detection distance - Support for detection of non-living objects - The directionality of the microwave is very good, and the speed is equal to the speed of light Specifications: - Working voltage: 5V±0.25V - Operating Current (CW): 60mA max., 37mA typical - Size: 61.2 x 61.2mm Emission parameters: - Detection Distance: 2-16m continuously adjustable (minimum 2m, maximum 16m) - Transmission Frequency: 10.525 GHz - Frequency Setting Accuracy: 3MHz - Output power (minimum): 13dBm EIRP - Harmonic emission: <-10dBm - Average current (5%DC): 2mA typ. - Pulse width (Min.): 5uSec - Duty cycle (Min.): 1% Receive Parameters: - Sensitivity (10dB S/N ratio) 3Hz to 80Hz Bandwidth: -86dBm - 10.3Hz to 80Hz Bandwidth Clutter 10uV - Antenna gain: 8dBi - Vertical 3dB beam width: 36 degrees - Water level 3dB Beam width: 72 degrees Package Included: - 1 x Microwave Radar Sensor Pin Description: Wiring Diagram: Routines: #include //Timer interrupt function Int pbIn = 0; // Define the interrupt PIN is 0, that is, digital pins 2 Int ledOut = 13; Int count=0; Volatile int state = LOW; //Define ledOut, default is off Void setup() { Serial.begin(9600); pinMode(ledOut, OUTPUT); attachInterrupt(pbIn, stateChange, FALLING); // Sets the interrupt function, falling edge triggered interrupts. MsTimer2::set(1000,process); // Set the timer interrupt time 1000ms MsTimer2::start();//Timer interrupt start } Void loop() { Serial.println(count); // Printing times of 1000ms suspension Delay(1); If(state == HIGH) //When moving objects are detected later, 2s shut down automatically after the ledout light is convenient. { Delay(2000); State = LOW; digitalWrite(ledOut, state); //Turn off led } } Void stateChange() //Interrupt function { Count++; } Void process() //Timer handler { If(count>1) //1000ms interrupt number greater than 1 is considereddetected a moving object (this value can be adjusted according to the actual situation, equivalent to adjust the detection threshold of the speed of a moving object) { State = HIGH; digitalWrite(ledOut, state); //Lighting led Count=0; //Count zero } Else Count=0; //In 1000ms, interrupts does not reach set threshold value is considered not detect moving objects, interrupt the count number is cleared to zero. } Note: The sensor has a continuous adjustable range of 2-16m, the potentiometer is adjusted along the MIN direction, the detection distance is reduced; the potentiometer is adjusted against the MIN direction, and the detection distance increases.
