Easily customize detection range and sensitivity to fit your space—minimize false triggers or maximize coverage for reliable presence sensing. Equipped with 60GHz mmWave radar, it detects even stationary humans by sensing micro-movements like breathing—eliminating false triggers in bedrooms and bathrooms. Powered continuously via USB-C (5V/1A) with no batteries needed. Supports Zigbee 3.0 and functions as a network repeater to strengthen your mesh coverage. Ddetects your presence and effortlessly triggers lights on when you enter, off when you leave—no switches to flip Intelligently opens blinds as you arrive in the morning, yet keeps them undisturbed while you rest—adapting to your stillness Powers your TV or devices while you're seated, then smartly cuts standby power when the room is vacant—saving energy automatically ## Features - Simplified 60 GHz mmWave Presence Detection: Utilizing advanced 60 GHz millimeter-wave radar, this technology accurately detects real human presence—even when you remain still—by sensing subtle micro-movements such as breathing. It is ideal for bedrooms, bathrooms, and other quiet indoor spaces where traditional motion sensors fall short. Instead of complicated parameter adjustments, only the detection distance needs to be set to prevent false triggers. - RGB Light with Visual Status Indication：The built-in RGB light is not only for ambient lighting, but also works as a visual indicator for presence, automations, or system status. Different colors or brightness levels can be used to clearly show room occupancy or smart home states at a glance. - Presence + Light, Designed to Work Together：By combining always-on presence detection with an RGB indication light, R3 enables more natural automations — lights remain on while you’re present and turn off only when the room is truly vacant, improving comfort and everyday energy efficiency. - USB-C Powered & Zigbee Repeater：Powered via USB-C (5V/1A), R3 delivers stable, continuous operation without batteries. Using Zigbee 3.0, it integrates smoothly with platforms like Home Assistant (ZHA & Z2M) and also functions as a Zigbee repeater to help strengthen your mesh network. - Ambient Light & Air Quality Awareness: Built-in ambient light (Lux) sensing and air quality (TVOC) monitoring provide additional environmental awareness to support advanced automations and insights when supported by your platform. Note: Availability of Lux and TVOC data depends on platform support. The indicator light will flash red when dangerous air quality is detected based on TVOC levels. - Fast, Stable Zigbee 3.0 Connection: Powered by low-energy Zigbee 3.0, it offers instant integration with Home Assistant via ZHA or Z2M, SmartThings (2015/2018), Aeotec and Echo devices with built-in Zigbee hubs, including Echo (4th Gen), Echo Plus (1st & 2nd Gen), Echo Studio, Echo Show 8 (3rd Gen), Echo Show 10 (2nd & 3rd Gen), Echo Hub, Eero 6, Eero Pro 6. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0GJZ3B7WY | | Best Sellers Rank | #10,725 in Electronics (See Top 100 in Electronics) #43 in Motion Detectors (Electronics) | | Brand | THIRDREALITY | | Built In Media | Motion Sensor R3 *1 | | Color | White | | Compatible Devices | Home Assistant (ZHA & Z2M), SmartThings (2015/2018), Aeotec, Echo devices with built-in Zigbee hubs | | Customer Reviews | 3.4 3.4 out of 5 stars (57) 3.4 out of 5 stars | | Frequency | 60 GHz | | Item Dimensions D X W X H | 1.42"D x 2.64"W x 2.76"H | | Item Weight | 0.3 Pounds | | Manufacturer | Third Reality, Inc | | Manufacturer Warranty Description | 1 Year Manufacturer | | Maximum Range | 6 Meters | | Model Number | 3RPL01084Z | | Mounting Type | Casual placement | | Power Source | USB-C Powered | | Smart Home Compatibility | Smart Home Compatible | | Upc | 810210140546 | ## Product Details - **Brand:** THIRDREALITY - **Color:** White - **Item Weight:** 4.8 ounces - **Maximum Range:** 6 Meters - **Power Source:** USB-C Powered ## Images ![Smart Presence Sensor R3, 60GHz mmWave Radar, USB-C Powered, RGB Light with Status Indication, Illumination Sensor, Zigbee Repeater, Compatible with Home Assistant(ZHA&Z2M), SmartThings - Image 1](https://m.media-amazon.com/images/I/51gB3oWEQZL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/807472635-smart-presence-sensor-r3-60ghz-mmwave-radar-usb-c-powered](https://www.desertcart.jp/products/807472635-smart-presence-sensor-r3-60ghz-mmwave-radar-usb-c-powered) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-15*
