Milweb™ Sleep - Sleep Depth Detection Solution
Non-contact sleep depth sensor utilizing millimeter wave radar technology. No Internet connection or cloud environment is required. It is a next-generation sleep tech solution that automatically provides a sleep environment suitable for each individual in conjunction with smart home appliances.

Features
- Utilizes millimeter-wave radar sensing technology to output sleep depth without physical contact.
- Outputs sleep depth in four stages: Awake, REM sleep, shallow sleep, and deep sleep.
- Operates as a standalone device to assess sleep depth in real-time, requiring no cloud connection.
- Compatible with Bluetooth® Low Energy and UART communication protocols.
- Enables seamless integration with smart home appliances through Matter compatibility.
Contactless yet Highly Accurate
Supervised by university experts, we developed a proprietary sleep-focused algorithm that enables high-accuracy sleep measurement.
As shown in the comparison graph below, it delivers contactless results comparable to contact-based EEG devices.

Applications
- Devices for sleep environment control (integration with motorized blinds, lighting, electric beds, audio systems, etc.)
- Sleep Environment Control Devices
Usage ~Just Place it by your Bedside

When the device is installed at a height approximately equal to the body, it is directed toward the stomach area without tilting, and when it is installed at a higher location, it is tilted.

The angle adjustment mechanism of the radar unit enables sensing from a height equivalent to or higher than the bed.
