Compatible with Alexa and Google Assistant, but doesn't support SmartThings and IFTTT. With a wired design ensuring stable power, it operates on 5V 1A USB power, eliminating the hassle of frequent battery changes. The communication range reaches about 263ft without obstacles - Ultra-High Precision Detection with More Privacy: Utilizing millimeter-wave radar technology, our human presence sensor accurately detects various movements, micro-movements, and stationary states. This ensures that lights won't unexpectedly go out during stationary activities like reading or toileting, without the need for a camera monitoring system, preserving user privacy - Advanced Sensing and Instant Alert: The 24GHz mmWave Radar smart sensor excels at detecting subtle movements, offering higher accuracy than PIR (not a presence sensor). It promptly sends alerts to your smartphone upon detecting unusual motion, enabling you to conveniently review 30-day activity logs through the app, regardless of your location - Customized Whole Home Automation: Utilize this motion sensor indoor as a motion-activated wall switch to automate various routine tasks by configuring "IF" conditions and corresponding "THEN" actions. For example, Reading Mode adjusts brightness, Child Monitoring Mode activates surveillance for safety, Energy Saving Mode minimizes consumption during the day. The seamless collaboration of these modes delivers users a precise and personalized smart home experience - Flexible Installation and Extensive Detection Range: The wifi presence sensor features a magnetic base that allows for 45° folding and 360° rotating, allowing you to mount it on the wall or ceiling with a maximum detection range of 20ft. Avoid installing it near swinging plants, moving metals, or fluttering curtains to prevent false detections. Note that the human sensor is not waterproof or moisture-proof, so ensure it’s installed in a dry area for long-term durability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CTMTZP73 | | Antenna Location | Indoor, Side-mounted | | Battery Description | Battery not included | | Best Sellers Rank | #48,009 in Electronics ( See Top 100 in Electronics ) #221 in Motion Detectors (Electronics) | | Brand | TREATLIFE | | Built-In Media | Human Presence Sensor*1, Magnetic Base*1, USB Changing Cable*1, User's Manual*1 | | Compatible Devices | Alexa, Google Assistant, Smartphone | | Customer Reviews | 3.8 out of 5 stars 129 Reviews | | Frequency | 24 GHz | | Item Type Name | motion detector device | | Item Weight | 4.16 ounces | | Manufacturer | TREATLIFE | | Manufacturer Warranty Description | 2-year quality warranty and lifetime technical support | | Maximum Range | 20 feet | | Mfr Part Number | PS-W1 | | Model Number | PS-W1 | | Mounting Type | Wall Mount, Ceiling Mount | | Number of Items | 1 | | Number of Packs | 1 | | Power Source | Corded Electric | ## Product Details - **Brand:** TREATLIFE - **Item Weight:** 4.16 ounces - **Maximum Range:** 20 feet - **Mounting Type:** Wall Mount, Ceiling Mount - **Power Source:** Corded Electric ## Images ![WiFi Presence Sensor 1 Pack, 24G mmWave Radar Smart Motion Sensor Wired, Support Alexa/Google Home, Real-time Human Occupancy Sensor, No Hub Required - Image 1](https://m.media-amazon.com/images/I/41gxeQ69wnL.jpg) ## Available Options This product comes in different **Style** options. ## Frequently Bought Together - TREATLIFE WiFi Presence Sensor 1 Pack, 24G mmWave Radar Smart Motion Sensor Wired, Support Alexa/Google Home, Real-time Human Occupancy Sensor, No Hub Required - GoveeLife Human Presence Sensor, 2.4 GHz Wi-Fi Required, Smart mmWave Radar & PIR Wired Motion Sensor, Zone Positioning, Multi-Person Detection, Support Alexa & Google Home, for Indoor Home Automation --- ## 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.ie/products/614024276-wifi-presence-sensor-1-pack-24g-mmwave-radar-smart-motion](https://www.desertcart.ie/products/614024276-wifi-presence-sensor-1-pack-24g-mmwave-radar-smart-motion) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-11-15*
