Very Functional and Easy to Setup, Small Form Factor and Great Accuracy

Very Functional and Easy to Setup, Small Form Factor and Great Accuracy
I'm very into home automation and security and always looking to improve my setup. I needed a small PIR motion sensor that was wireless and would work with the rest of my system. It also needed to have a high level ability to integrate with other assets such as security systems and customization services. This was a perfect match for those requests and at a great price point. The Gaoducash WiFi Smart Motion Wireless PIR Sensor came well packaged and with everything you need to set it up. The form factor is really good, picture those old school single button long rectangular door bells, it about the same exact size, small. It takes two AAA batteries, which are included with the kit. I recommend using lithium triple As with this and all home automation and security devices. It comes with an adhesive pad, but I used my own because I prefer the one I have used in other installs. The sensor works with the Tuya App and the SmartLife App, and I chose to put it on my android phone. It's WiFi and links to your 2.4ghz network, it won't work with 5ghz or 6ghz nets. Once you link it up and get it recognized in the app you are set to start hooking up what devices in your home you want triggered with the sensor. It has a good amount of options in the app, and most importantly you can adjust the sensitivity. I have it linked to some small LEDs and camera near my cats outside door. I wanted to be alerted to when my cat enters or leaves the house and also record the motion. This sensor did a great job of triggering what I chose to put on it, it rarely ever produces false triggers. The alert time seems reasonably quick and I love the versatility it has with being able to trigger almost any other device I have in my setup, which is over 60 devices and 9 different brands, all of them were compatible with it. Overall, very happy with this choice of sensor, it's constructed well, easy to setup, accurate to use and has great versatility. 5 Stars!

    I wish this worked without having WiFi. I love everything about it except I can’t put it anywhere that has no Internet. I wanted it for my car to let me know if anyone walked passed it but it won’t work there. However, it works for anything else that you might want to use it on like they state.

    It’s wonderful if you get a good one. I bought 3, 2 were good, 1 eats battery and goes offline often. These are helpful for me to monitor my teen’s morning movements. He needs to get up and go to school and come home by himself. And he is at the age that hates to be told what to do, so I try not to call him every morning to make sure he is up. I put 1 in the bathroom and 1 at the door and set up alerts on my phone, so I know if he is up and sets out to school (if not I’d call him). This allows him to be independent under minimum supervision. Has been working well for the past 2 months. He has never been late for school, a win!

    Work Perfectly! Recommended!

    Reviewed in the United States on December 31, 2024

    Color: 2-PackVerified Purchase

    Received replacement. They all work as advertised and a little too good too! I will put some black tape on sides just so I can get a direct line of motion instead peripheral full field view. Works great for now. Took a bit for replacement. But I can't complain. Definitely Recommend if this is exactly what your looking for.

    But the second óne works very badly; in fact the app will not let me use the same selection criteria as the first one. Since the 1st one really works good. But the second one does not work at all. Returning the second one and hope I get a good one again. It's a gamble. If the next one works like the 1st one, I would have to give 5 Star. Right now it's 50-50. I really tested everything once the 1st one worked, I was excited but tried to copy the same techniques only to find out, reset after reset, that this is a bad one. 1st works so well with Alexa, Too!

    Wait and see if I get another good one on the return of this bad one!

    Extremely low sensitivity even in a small room.

    Extremely low sensitivity even in a small room. What't the point of having this motion sensor if it only triggers once in a while when there are people constantly moving in and out of the room the whole time. And it sometimes won't trigger for over an hour. Perhaps they are trying to sell the texting subscription plan. Seems to trigger less frequently as the days go by.

    I hung string lights over my driveway but I have to manually turn so the kids can play outside. I found this motion sensor, but wasn't sure if it will work with my Alexa and Google Home. To my surprise, I was able to get it to work exactly the way I wanted within 20min from opening the box! Make sure you can use your Alexa and/or Google Home can control your device first. It is plugged into my Wyze outlook plug and Alexa is able active it, but I prefer it to be activated by motion instead. Here are the steps in case anyone wondering.

    1. Install the "Smart Link" app and create an account
    2. Add the motion sensor to the Smart Link app.
    (Once you pull the battery tab, it goes into pairing mode and apps detects it.)
    3. I use the Wifi Protocol to pair it. I had to enter my wifi network password.
    4. Smart Link allows you to link with Alexa and Google Home.
    5. Once linked, create a routine where condition is motion detected from 5pm – 5am with Alexa turning on the driveway light.

    Purchase this so I would be alerted of mail deliveries. Simply placed it in the inside bottom of the mailbox. It's been working without any issues. Does not require a subscription to use. My only grip is that the sensor is picking up the vibration from the door being closed which causes it to send an alert.
