Description

The HB100 Microwave Doppler Radar Motion Sensor operates on the Doppler principle, detecting movement by analyzing frequency shifts in reflected radio waves. Its integrated Dielectric Resonator Oscillator (DRO) and microstrip patch antenna array provide stable 10.525 GHz signal transmission and reception, ensuring reliable motion sensing even in challenging environmental conditions.

Designed for low-current operation, this module outputs a baseband Intermediate Frequency (IF) signal proportional to target velocity, which can be processed by external amplifiers and microcontrollers. Its flat profile and robust construction make it suitable for integration into compact alarm systems, automatic lighting controls, and industrial motion detection equipment.

Key Features

  • X-Band Doppler Radar: Operates at 10.525 GHz for precise motion and speed detection.
  • Integrated DRO & Antenna: Built-in Dielectric Resonator Oscillator and patch antenna array for a compact, self-contained design.
  • Low Power Operation: Consumes approximately 30 mA at 5V DC, suitable for battery-powered applications.
  • Extended Detection Range: Capable of sensing motion up to 20 meters under optimal conditions.
  • Bi-Static Transceiver Architecture: Separate transmit and receive paths for improved signal isolation and sensitivity.
  • CW & Pulse Mode Compatible: Supports continuous wave or pulsed operation for flexible system design.
  • ESD Sensitive Design: Requires careful handling and proper grounding during soldering and installation.

Applications

  • Intrusion Detection and Security Alarm Systems
  • Automatic Door Activation and Lighting Control
  • Traffic Monitoring and Vehicle Speed Measurement
  • Presence Detection in Smart Home and Building Automation
  • Industrial Machine Guarding and Motion-Activated Safety Systems

Frequently Asked Questions

What is the operating voltage range for the HB100 radar module?

The HB100 module requires a regulated DC supply voltage between 4.75V and 5.25V. Operating outside this range may affect oscillator stability and output signal integrity. A clean 5V power source is recommended.

How do I interface the HB100 sensor with an Arduino or microcontroller?

The HB100 outputs a low-level Intermediate Frequency (IF) signal. This signal must be amplified and filtered using an external op-amp circuit before being fed into an analog input or comparator on your microcontroller for processing the Doppler shift information.

What precautions should be taken when handling and soldering the HB100 module?

The HB100 is highly sensitive to Electrostatic Discharge (ESD). Use a grounded soldering iron and work on an ESD-safe mat. The IF output pin is particularly sensitive. Verify module integrity by checking the forward voltage drop between the IF pin and GND, which should be approximately 0.25V.

Can this sensor detect stationary objects or only moving targets?

The HB100 operates on the Doppler principle, which requires target motion to generate a frequency shift. It cannot detect stationary objects. It senses movement and can provide information related to the velocity of a moving target based on the Doppler shift magnitude.
