HB100 Microwave Doppler Radar Wireless Motion Sensor

The HB100 Microwave Doppler Radar Wireless Motion Sensor operates on the Doppler Principle. It emits radio waves that, when encountering a moving object, are reflected back with a frequency shift. This shift in frequency is used to detect motion. The sensor includes a Dielectric Resonator Oscillator (DRO) and a Microstrip patch antenna array for detecting the motion.

Doppler Radar Sensor

• Avoid High Voltage Soldering Tools: Do not use high voltage soldering tools as they may damage the sensitive components of the sensor.,
• Neglect Esd Precautions: Do not neglect ESD precautions; the device is sensitive to electrostatic discharge.

• Use A Low Voltage Soldering Iron: Ensure the soldering iron is low voltage and properly grounded to prevent damage to the device.,
• Check For Damage With A Multimeter: Use a multimeter in diode mode to check for damage. The forward voltage drop between IF and GND should be about 0.25 V.

• Maximum: 20 meters,
• Description: The sensor can detect motion up to a distance of 20 meters.

• Range: 4.75 ~ 5.25 VDC,
• Description: The sensor should be powered within this voltage range to ensure proper operation without damage.

• Tutorial Link: Refer to the tutorial on interfacing the HB100 Microwave Motion Sensor with an Arduino for detailed steps and code examples.
