24GHz mmWave Radar Sensor – Fall Detection Module

The 24GHz mmWave Radar Sensor – Fall Detection Module operates using Infineon mmWave FMCW industrial radar technology. It utilizes Doppler radar technology with a Near Distance Sensor (NDS) to detect human activities such as standing, moving, and falling. The sensor distinguishes between occupied and unoccupied conditions and identifies human activities in a self-adapting environment.

Near Distance Sensor (NDS)

• Avoid Extreme Conditions: Do not expose the sensor to temperatures outside the range of -20 to +60°C for operating and -40 to +80°C for storage.,
• Prevent Obstruction: Although the sensor can operate properly regardless of shelter blocks, avoid placing objects directly in front of the sensor that might completely obstruct its sensing capability.

• Ensure Proper Installation: Install the sensor in a location where its fan-beam pattern (Horizontal 90° and Vertical 60°) can cover the desired area effectively.,
• Maintain Operating Conditions: Keep the sensor within the operating temperature range of -20 to +60°C and ensure the operating voltage is between 4.5 to 6V.

• Motion Perception: Maximum distance up to 12 meters.,
• Micromotion Perception: Maximum distance up to 5 meters.,
• Body Perception: Maximum distance up to 3 meters.

• Temperature: Operates effectively within a temperature range of -20 to +60°C.,
• Humidity And Other Factors: Designed to function properly in complex environments with varying temperatures, humidity, noise, air currents, dust, and light.

• Manage Output: Handle the output data from the sensor for further processing or integration into other systems.

• Voltage: Connect a power source that supplies between 4.5 to 6V.,
• Current: Ensure the power source can provide 90 to 100 mA of current.

The sensor measures 11 × 7 × 1 cm and weighs 0.004 kg.
