Consider our Garage Door Sensor or smart garage door kits Pair your sensor with the YoLink Siren Alarm, for security applications Pair your sensor with smart plugs/outlets and control lights and other 120V-powered devices/equipment with a YoLink In-Wall Switch, In-Wall Outlet, Plug, Plug Mini, Power Strip, or Outdoor Plug PACKAGE CONTENTS: (1) Outdoor Contact Sensor with Magnetic Contacts (2) "AA" Batteries (4) Self-Tapping Screws (1) Double-Sided Mounting Tape (1) Quick Start Guide Review: It's very useful, has proven reliable, and is low-cost for what it is and does - This sensor is part of a number of Yolink smart appliances I use. It performs perfectly, reliably, and installed relatively easily. The electronic part of installation is easy, as part of the Yolink suite of sensors. The mechanical part was relatively easy. I'm using it as a steel gate monitor, and it apparently is intended for wood gates and doors, so the included wood screws weren't used. In my case, to mount the unit I super-glued the magnet portion to the swinging gate and zip-tied the Hall-sensor portion to the static frame of the gate. It is AA battery operated, and batteries were provided. It has been in place for nearly a year and it has worked without missing an opening of the gate or alarming for a false opening the entire time. it maintains a history of openings and closings. An Open reminder can be set, so the user is notified if the gate remains open for a settable period of time. This feature is the primary reason I purchased the unit. After nine months the battery level shows as full. The signal intensity also is shown by the app, and it shows Strong (-59 dBm) in my case where the receiver is 25-30 ft away and inside the house. The receiver (hub) connects wirelessly to my AP. As with all the Yolink sensors, I have no complaints. The cost was reasonable for the quality, reliability, and satisfaction it provides. Review: Excellent product - I have been using YoLink products for 4 years now. This is another great product of theirs. Simple to install, great battery life and does a great job of what it’s supposed to do. Best thing is the long range. No more worrying about whether your Wi-Fi signal is going to be strong enough, YoLink products use LORA, which is a low frequency, long range radio wave system that gives up to 1/4 mile range. I have YoLink sensors as far as 800’ from my hub and no problem. With the 40 or so YoLink sensors I have, I’ve had to deal with YoLink tech support a few times and have always found them to be over-the-top excellent in their response, even going so far as to send me replacements as long as several years after my purchase. I’m an electrical engineer with a specialty in digital communication and I design radio frequency communication products among other things. I have nothing but good things to say about YoLink products and support. I have over 180 smart products of various brands in my homes and boat and YoLink products are among the easiest and best. Their app is also very comprehensive and feature rich. I use this contact sensor to interface some of my own circuit boards with my IoT devices. ## Features - PROTECT YOUR PERIMETER and prevent crime at your property line!

The metal seems to be disrupting the magnetic sensors from working.** A: I would mount the magnetic sensor INSIDE the metal mailbox, route the wire thru a small hole UNDER the mailbox, and mount the TX transmit device inside a small weather proof external plastic box.this could be mounted on the side of the post holding the mailbox, not seen from streets. The cost would be minimal. The sensor would take up minimal footprint inside the mailbox, the wires secured/routed to the mailbox metal via silicon glue, keeping them out of the way. This is what I would do, personally. Hopefully, this will give you ideas to consider. **Q: Is it there any picture of the product installed?** A: Yes, we have an installed picture. Please kindly contact us for more information. As for the installation of the Outdoor Contact Sensor, please kindly refer to the following guide http://www.yosmart.com/support/YS7707-UC/docs/instruction **Q: Can the " open too long" feature be disabled for part of the day?** A: You can customize an alarm strategy for the YoLink contact sensor, turn on the "Do not disturb" and set the time you do not want to receive notifications including the "Open Remind". **Q: how long are the wires?** A: It's around 12 inches. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's very useful, has proven reliable, and is low-cost for what it is and does *by J***D on 27 April 2026* This sensor is part of a number of Yolink smart appliances I use.

Extremely easy to add via the QR code on the product. The signal is great given the hun is in the basement while the door sensor is on the shed 18 ft from the house. Works extremely well and is a great add on to the other sensors/monitors that I have operating. Definitely with its price. Highly recommended. ## Frequently Bought Together - YOLINK LoRa Smart Outdoor Contact Sensor, Gate & Shed Door Sensor, Universal Contact-Closure Sensor, Email/SMS/Push Alerts, 1/4 Mile Range, Alexa, IFTTT, Home Assistant (Hub Required) - YoLink LoRa Smart Door & Window Sensor 3-Pack: Door Left-Open Reminders, up to 1/4 Mile Open-Air Range, up to 5 Year Battery Life, Alexa, IFTTT, Home Assistant --- ## 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.tn/products/413558009-lora-smart-outdoor-contact-sensor-gate-and-shed-door-sensor](https://www.desertcart.tn/products/413558009-lora-smart-outdoor-contact-sensor-gate-and-shed-door-sensor) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-06*
