Radar Module - Making TVs Smarter

From “Always-On” to “Always-Aware”: Why TVs Need Radar Sensing

Traditional on/off or standby modes rely on remotes or voice commands. Even in the so-called “smart-TV era, ” most sets still suffer from:

• User walks away → screen stays on, wasting power
• Voice assistant always listening → must be woken manually, easily interrupted
• Zero awareness → no clue whether anyone is actually watching

Compared with legacy IR or camera solutions, millimeter-wave radar is born for the TV scene:

Real-World Magic: What a Radar-Equipped TV Can Do

1. Auto wake/sleep

Lights up when you approach; it dims or enters deep standby after you leave.

2. Voice-wake helper

It only activates the mic when someone is present, which means stronger privacy and fewer false wakes.

3. Smart-home choreography

Detects entry/exit from the sofa zone to trigger lights, AC, curtains, etc.
