HB100X Microwave Doppler Radar Motion Sensor Module 10.525GHz

HB100X Microwave Doppler Radar Motion Sensor Module

The HB100X Microwave Doppler Radar Motion Sensor Module is a compact, high-performance wireless detection module built around the industry-standard HB100 chip. Operating at 10.525 GHz, it uses Doppler radar technology to reliably detect moving objects across a range of 20+ meters — all without physical contact. Whether you're building a security system, smart door controller, or automation project, this module delivers consistent, accurate results even in demanding environments.

How It Works

Based on the Doppler principle, the module continuously emits microwave signals. When those signals strike a moving object, the reflected frequency shifts — and the module detects that change. If an object is stationary, the reflected frequency matches the transmitted frequency and no trigger occurs. This makes the HB100X ideal for distinguishing genuine motion from background interference.

Key Advantages Over Other Detection Methods

• Non-contact detection — no physical interaction required
• Environment-independent — unaffected by temperature, humidity, noise, air, dust, or lighting conditions
• Strong anti-RF interference — stable performance in electrically noisy settings
• Low output power — safe for everyday use
• Long detection range — detects movement at distances exceeding 20 meters

Frequently Asked Questions

Q: What is the HB100X Microwave Doppler Radar Motion Sensor Module used for?

A: The HB100X is a 10.525 GHz Doppler radar sensor module designed to detect moving objects without physical contact. It is widely used in automatic door controllers, security systems, ATM video automation, train signal systems, and custom DIY electronics projects. Its detection range extends beyond 20 meters, making it suitable for both short- and long-range motion sensing applications.

Q: What makes the HB100X better than infrared or ultrasonic motion sensors?

A: Unlike infrared sensors, the HB100X is not affected by temperature, lighting, humidity, or dust — making it far more reliable in harsh or variable environments. Compared to ultrasonic sensors, it offers a significantly longer detection range (20+ meters) and stronger resistance to RF interference, ensuring consistent performance in electrically noisy settings.

Q: What voltage does the HB100X module require to operate?

A: The HB100X operates on DC 5V (±0.25V), drawing a typical current of 37 mA in continuous wave mode. In pulse mode at 5% duty cycle, the average current drops to just 2 mA, making it highly efficient for battery-powered or low-power applications.

Q: How many units can I order at once?

A: The HB100X Motion Sensor Module is available in three quantity options: 1 PC, 5 PCS, or 10 PCS. Choose the pack size that best suits your project needs — larger packs offer better per-unit value for multi-unit builds or prototyping.
