Introduction

In today’s world, human presence detection plays a crucial role in various applications, from smart home automation to industrial safety. The 24GHz FMCW human presence sensor is an advanced solution that accurately detects people in a given space, even in challenging environments. Unlike traditional motion sensors, FMCW (Frequency-Modulated Continuous Wave) technology provides high precision by detecting even the slightest movements, such as breathing.

This blog explores the working principles of human presence sensors, their applications, and the advantages of pulse detectors, Crux detectors, and the Master Pro presence sensor in modern detection systems.

Understanding 24GHz FMCW Technology

What is FMCW?

FMCW (Frequency-Modulated Continuous Wave) is a radar-based sensing technology that continuously emits a frequency-modulated signal. When this signal bounces off an object, the sensor measures the frequency shift, enabling it to determine the object's presence, distance, and movement with extreme precision.

Why 24GHz?

The 24GHz frequency band offers a perfect balance between range, resolution, and penetration capabilities. Compared to lower-frequency sensors, 24GHz sensors can detect fine movements such as a person’s pulse or breathing, making them ideal for advanced human presence detection.

FMCW vs. Traditional Sensors

Key Features of a Human Presence Sensor

A human presence sensor is more advanced than a simple motion detector. It can:

• Distinguish between human presence and other objects.
• Detect micro-movements such as breathing and heartbeat.
• Work in various lighting conditions, including complete darkness.
• Operate in enclosed spaces (through materials like glass or thin walls).

The Role of Pulse Detectors and Crux Detectors

• Pulse Detector: Detects small human motions like heartbeats or breathing, making it useful for healthcare and security applications.

• Crux Detector: Enhances the sensor's ability to differentiate between human presence and background interference, increasing accuracy.

Applications of Human Presence Sensors

The 24GHz FMCW human presence sensor is widely used across various industries:

1. Smart Homes & Offices

• Automated lighting: Lights turn on/off based on human presence.
• HVAC optimization: Air conditioning adjusts based on occupancy.
• Enhanced security: Detects intruders even if they remain motionless.

2. Healthcare & Elderly Care

• Non-intrusive patient monitoring: Detects breathing patterns without physical contact.
• Fall detection systems: Alerts caregivers if an elderly person falls and remains motionless.

3. Industrial & Automotive

• Factory Safety: Prevents machinery from operating when humans are too close.
• Driver monitoring systems: Detects driver fatigue by monitoring breathing and small movements.
