Its 400-inch reliable range and included lithium battery make it a practical addition to any connected home. ## Description The Aqara Door and Window Sensor T1 detects the open and close state of doors or windows through the distance between the sensor unit and the magnet. It consumes a minimal amount of energy. No tools are required, just stick it to the desired place and use it in a dozen of possible use cases. Review: New Sensors - Lower Battery - The sensors are great. Bummed Aqara sent me dead stock that is only at 84% battery life. Review: Dead on Arrival - I thought I was going to find a zigbee door sensor that was more reliable than the IKEA parasoll but found one even worse. Showed up with a dead battery, but even after replacing the battery I didn’t get more than the brief flash at install. Pairing does not work. Proximity does not work. ## Features - Note: Requires an Aqara Hub (sold separately) and a secure 2.4GHz Wi-Fi connection (Hub M2 also supports Ethernet). Not compatible with hubs from other brands. - Connection Range: For stable performance, keep the sensor within 400 inches of the Aqara Zigbee Hub, and ensure the hub is within the same distance from your Wi-Fi router. Both must be on the same local network. - Security Alerts & Automation: Get instant alerts on your phone and trigger alarms on the Aqara Hub if a door or window opens unexpectedly. Easily automate other Aqara devices based on door or window status for enhanced home security. - Wide Compatibility: Works with most doors, windows, drawers, and cabinets with gaps up to 0.86 inch. Sensor size: 1.61×0.87×0.43 in; Magnet size: 0.79×0.39×0.39 in. Ensure installation surfaces are flat and adhesive-friendly. - Hands-Free Voice Control: Compatible with Apple HomeKit, Alexa for a hands-free experience.- no need to go downstairs or pick up your phone again. You'll always know whether your home door is opening or closing. (Not compatible with SmartThings.) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CTQCGT8X | | Antenna Location | Indoor | | Battery Average Life | 2 years | | Battery Cell Type | Lithium Metal | | Best Sellers Rank | #160,767 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #161 in Motion Detectors (Electronics) #166 in Home Automation Hubs & Controllers #1,865 in Home Security & Surveillance Systems | | Brand | Aqara | | Built-In Media | Sensor Unit x 1, Magnet x 1, Sticker x 2, Quick Start Guide x 1 | | Color | White | | Compatible Devices | Smartphone, Tablet | | Control Method | App | | Customer Reviews | 4.2 4.2 out of 5 stars (81) | | Item Dimensions | 1.57 x 0.79 x 0.39 inches | | Item Type Name | Sensor | | Item Weight | 25 Grams | | Manufacturer | Lumi United Technology Co., Ltd. | | Maximum Range | 400 Inches | | Mfr Part Number | DW-S03D | | Model Number | DW-S03D | | Power Source | Battery Powered | | Sensor Technology | Contact Sensor | | Smart Home Compatibility | Smart Home Compatible | | UPC | 192784001240 | | Voltage | 3 Volts (DC) | ## Product Details - **Brand:** Aqara - **Color:** White - **Compatible Devices:** Smartphone, Tablet - **Item dimensions L x W x H:** 1.57 x 0.79 x 0.39 inches - **Power Source:** Battery Powered ## Images ![Door and Window Sensor T1, Mini Wireless Contact Sensor for Smart Home Security and Automation, Requires Aqara Hub, Zigbee 3.0, Works with Apple HomeKit, Alexa, IFTTT - Image 1](https://m.media-amazon.com/images/I/61IV7Ll7OGL.jpg) ## Customer Reviews ### ⭐ New Sensors - Lower Battery *by A***R on February 24, 2026* The sensors are great.
