Merrytek 3^rd Generation Lifebeing Presence Sensor

Experience the ultimate performance of 24GHz millimeter-wave radar.

 

 

8m Diameter Presence Detection Range

Approaches a near-perfect circular coverage range

 

Merrytek 3^rd generation Lifebeing Presence Sensor integrates German’s Infineon automotive-grade chip with Merrytek self-developed patented antenna technologies. It enables highly overlapping detection ranges in the same spatial for major gross-motor movements, minor fine-motor movements, and subtle respiratory motion, covering a maximum diameter of 8 meters. The detection area coverage forms an almost ideal circular pattern, providing precise activation thresholds and comprehensive, real-time omnidirectional sensing.

 

 

 

 

 

The data in the image was collected from a male subject, 1.72 meters tall and weighing 75 kilograms, walking directly toward the sensor at a speed of 0.5 m/s in an open indoor environment, with no obstructions over his chest or abdomen.

 

Anti-near-field interference

Customizable elimination of far-field interference

Accurate detection without false alarm

 

Utilizing a 24GHz millimeter-wave radar chip and integrated with Merrytek’s proprietary and patented core algorithm, the Merrytek 3^rd generation Lifebeing Presence Sensor features reinforced and enhanced anti-interference capabilities. In unoccupied states, it can identify and exclude common interference sources within the detection area, such as robotic vacuum cleaners, oscillating fans, and minor movements from small plants, ensuring zero false activations during regular operation.

 

With the addition of a near-field interference shielding function, it effectively blocks interference from sources such as ceiling-mounted pipe vibrations, hanging sign movements, exhaust fans, and air conditioner outlets. This ensures stable sensing without self-triggering.

 

 

Supports far-field distance range setting and interference elimination functions, allowing for 8 adjustable distance intervals. This effectively excludes interference sources within specified zones, enhancing the accuracy of human presence detection.

 

 

Multi-scene zoned deployment

Effective Energy Saving

Multi-scene zoned deployment for indoor spaces, allowing each area to sense independently without interference between zones. Clearly defined detection boundaries enable lights to activate in response to movement, preventing false triggers in adjacent zones and facilitating precise energy savings and efficient management.

 

 

Application scenarios

 

Home scenario

 

• Home unoccupied: Automatic activation of the robotic vacuum cleaner for cleaning
• Returning home from work: Remote controlling and pre-activating devices such as air condition and underfloor heating through platform; Upon arrival at home, automatically turns on lights, curtains etc.
• Daily Presence at home: Real-time sensing of ambient light levels allows smart lighting to automatically adjust brightness, ensuring a consistently comfortable lighting environment.
• Getting up in the middle of the night: Automatically turn on the nightlight, ensuring safe navigation without stumbling in the dark.

 

Office scenario

 

• Lights on when people presence: Upon sensing someone entering the office area, the lights are turned on immediately
• Constant lighting: By considering the presence of individuals and real-time ambient light levels, maintain a constant illuminance level for a comfortable office environment.
• Meeting room management: Detect the status of individuals entering or leaving; automatically activate lights, air conditioning, and other devices when individual enters, and automatically turn off the devices after a period of absence.

 

Hotel scenario

 

• Cardless power activation:  Upon detecting a guest entering the room, automatically provide power and activate the lights, air conditioning, curtains, and other devices, switching to ‘Guest Mode’ within one second. When a guest leaves the room and it remains unoccupied for an extended period, switch to ‘Unoccupied Mode’ and automatically turn off the room’s devices.
• Energy-saving management: Enable automatic lighting control in public areas such as corridors, passageways, stairwells, and elevator lobbies. Lights turn on when someone approaches, remain on while occupied, and turn off when the area is emptied, effectively managing energy consumption.
