HB100 Human Presence Radar Sensor 10GHz, Range up to 20m

The HB100 sensor is a type of microwave motion sensor module that is used to detect the presence of moving objects. It works by emitting microwave signals and then measuring the reflection of those signals off of objects within its detection range. The sensor is able to detect motion within a range of up to 20 meters, and it has a detection angle of 360 degrees.

The HB100 sensor emits continuous wave (CW) signals at this frequency and measures the Doppler shift of the reflected signals to detect motion. The Doppler shift is a change in the frequency of the reflected signal caused by the motion of the object relative to the sensor, which allows the sensor to determine the speed and direction of the object.

Interfacing HB100 with Arduino

Arduino Code for HB100

    #include <FreqPeriod.h>

    double lfrq;
    long int pp;

    void setup() {
      Serial.begin(9600);
      FreqPeriod::begin();
      Serial.println("FreqPeriod Library Test");
    }

    void loop() {
      pp = FreqPeriod::getPeriod();
      if (pp) {
        Serial.print("period: ");
        Serial.print(pp);
        Serial.print(" 1/16us / frequency: ");

        lfrq = 16000400.0 / pp;
        Serial.print(lfrq);
        Serial.print(" Hz ");
        Serial.print(lfrq / 31.36);
        Serial.println(" Mph");
      }
    }
