Essential Info

Add to your Cao Gadgets Wireless Sensor Tag Manager Controller (sold separately) with a Wireless Motion and Temperature Sensor Tag. This tiny sensor (0.28" thick) wirelessly transmits temperature readings and motion notifications back to the Wireless Sensor Tag Manager and can even be used as an item finder by activating the sensor to beep to locate the tag. Each sensor has a communicating range of up to 700 feet from the Tag Manager and if the sensor is ever out of range or not transmitting, users are notified via text, email or tweet. A Velcro strap is included with the sensor tag that make it easy to strap the sensor to a door, drawer or window handle to monitor for movement or even attach it to the garage door arm to monitor its status. With the option to support up to 255 Cao Gadget sensor tags on the Wireless Sensor Tag Manager, users can easily monitor an entire home without the hassle of difficult installation; even monitor the temperature of a refrigerator by dropping one of these sensor on an a shelf inside the fridge. The sensor tag is powered by a CR2032 coin cell battery and is protected by an elastic covering that keeps the sensor protected if dropped.

    I can't say enough good about the Cao Wireless sensors. I have installed them around my property to alert me on the condition of doors, gates and windows and they work like a charm. The app for the iPhone is always being updated and is very responsive when a sensor is triggered. Best of all they are easy to setup and easy to manage. It's a really great system that fully does everything that is advertised.
    Mathew James -- Winchester VA   6/9/2014
    I was looking for a way to monitor the temperature on each floor of my three-story townhouse. These showed me just how much cooler/hotter the different floors are and how I could better use my programable thermostat. I've also used them for other little projects such as monitoring the temperature of a failing refrigerator and as a motion alarm on the door of a locked room.
    Michael -- houghton, Michigan   4/9/2014
    This sensor tag is fantastic. I use it as a remote monitor of temperature when I am away from home. It has performed flawlessly over the past 5 months and alerted me to a potentially very damaging furnace outage. The cost of this sensor is minimal and this tag performs much better than others that I have tested. Good value, solid performance
    1 angry customer -- san fran, CA   4/4/2014
    These would be great, if you actually were to get the covers for the sensors. Be very aware that the idea behind this is great, but the customer service is horrible!
    Christopher J West -- philadelphia, PA   3/31/2014
    bought this to help keep an eye on my grandmother who wanders sometimes at night, due to Alzheimers. It is a big help and while it took a lot of fine tuning and trial and error to figure out what all the settings did, is now reliable and great!
    Tom Oswald -- london, UK   3/25/2014
    Have been using these sensors for a few days now - and they're great. I especially like the ease of use of both the Web based app and the iOS app. Very easy to change the settings. Works are I had hoped. Highly recommend.
    Marcis -- riga, Latvia   3/14/2014
    Bought to monitor temperature on my house second floor. As i use manual wood heating system i can rugulate my flow of heat according to readings on my iphone. It was super easy to set up also. Also motion detection is nice feature too.
    John -- irvine, CA   3/13/2014
    I was looking for a reliable way to monitor my garage door. So many times I drive away, only to have this gut feeling that I didn't close the garage and end up turning around, only to have actually closed the garage! I have in the past left the garage door open a few times whether being at home or driving away on accident, and due to my error, had things stolen out of my garage as well!. The instant my garage door starts to open even just 1 inch off the floor, or after it fully closes only alerts me when it is back to its original position, so if it is partially/almost closed, even with it being 3 inches off the floor, it will still tell you your garage is open, I get an instant and reliable push notification to my iPhone. I can also open the app and tells me whether the garage is open or closed. I say instant and reliable, because I am a very paranoid person after having things stolen out of my garage and because I use the garage as storage as well, I have also installed a Chamberlain MyQ which also does essentially the same thing as the Tag and Tag Manager. It gives me push notifications any time my garage door opens or closes through the cloud. Unfortunately, MyQ is not dependable. It has a very slow response time, anywhere from a few seconds to a minute, and often enough, their server is down, causing delayed notifications to come in hours later, sometimes never at all, and/or sometimes randomly when no movement has occurred, while the Tag notifies me every time and instantly. If someone were to break into my garage while I am not at home, there is not much I can do, but at least I will know that its happening. The Tag works in notifying me instantly and consistently, and can be used for everything else, such as knowing when my wife opens and closes the garage, when she walks through the door, that the windows are closed, to knowing that the refrigerator door is fully closed! As someone said, excellent product with many applications!
    HomeControl -- olympia, Washington   3/12/2014
    I bought the tag with the tag manager to see if this system would be what I was looking for in a starter home monitor system. The cost was right and it seemed to provide the right functions I was looking for. The tag detects motion when it is moved and also monitors the temp. Both is a plus for me. To try it out I mounted the tag to my mailbox door over 200 feet away. Now I can monitor when mail is delivered and the outside temp. I plan on ordering more as I see they have come out with some tags that will monitor an open and closed door with contacts.
    Dave in Chicago -- chicagoland, USA   3/10/2014
    Nice product. Installed 6 sensors in my dog boarding kennel to monitor localized temps in our large facility. Easy to install, easy to monitor. Good range on the emitter too - through cinderblock and several hundred feet from the base station. Highly recommended.
    Ken -- richmond, Va   3/10/2014
    Awesome little device for the cost! And check out their kickstarter initiative for more direction on where the product is evolving to. Additionally, you can use twitter or emails to link this to IFTTT to control other things in your house. We have a tag hooked to a 100 watt light bulb in a pump room - when the temp drops below 35, the tag create a tweet that's picked up by ifttt, which triggers the wemo light switch.....100 watts is just enough heat to do the trick!!! Great product - very stable - great price - promising future!
    Larry -- ventura, California   3/10/2014
    The Cao Gadgets Wireless Motion and Temperature Sensor Tag is working great. Use it to monitor the garage door, no more circling back to make sure we remembered to close it.
    Phil -- westminster, CO   3/10/2014
    This tag is great: I keep it on my keychain for presence detection with my home automation software. I had to calibrate the temperature sensor, but that was easy.
    eric_mango -- tempe, Arizona   3/10/2014
    This is the engineer's tag. It is very configurable and in basic testing that I have done it seems to live up to the manufacturer’s claims. It seems particularly strong in uses cases where motion needs to be detected on tagged items that are rarely moved, or where remote activation of the tag beeper is used to find lost objects. In these cases tag configuration should support very long battery life I have not quantified the actual limits of battery life yet. For use cases that need to generate an alert when a tag goes out of range of the manager, battery life will probably be a little shorter, depending on the configured latency of the out of range alert. The RF link from the manager to the tag seems much more robust than the link from the tag to the manager. I was able to cause the tag to beep when it was about 900 feet from the manager through several sheet rock walls. Pretty amazing! At this location the manager could not receive the transmissions from the tag, however the range where the bi-directional link was supported, was still very impressive for a coin cell system. The smartphone apps and cloud server apps seem to work as advertised. Overall the product seems to have been well thought out and it appears that other compatible sensor offerings are in the works. The design stresses configurability over simplicity which will be the right tradeoff for some people, just expect to have to do a little experimentation to figure out the right settings for your application. Disclaimers – I am not affiliated with the manufacturer. As a result of a manufacturing delay in providing the plastic tag enclosures they were offering a free tag in exchange for a review and that was my incentive to write this.
    bruce -- phoenix, AZ   3/10/2014
    I used the motion sensors as a sign of life monitor for my 88 years old mother in Honolulu. The motion sensors and on the refrigeraor/bath door, and as long as they are being moved, I know she's okay. Can monitor remotely in PHX via my computer or ipad.
    Jiro -- omaha, NE   3/10/2014
    Super easy to set it up. I will be using it to monitor the door status at my house as well as monitoring temperature.
    Tesla -- morrisville, NC   3/10/2014
    This is a great affordable home insight option. I have been experimenting with my sensors for a few weeks now and plan to expand. It is very interesting to be able to measure temperatures all over the house for example. The batter life is actually much better than I anticipated.
    Troy P. -- Pine Brook NJ   3/10/2014
    Used in a wine distribution center to ensure temperature is being controlled properly. The sensor was easy to set up and keeps a record that can be later reviewed. It was the best option available and have purchased a total of 14. By far the best way to go if looking to monitor temperature.
    Eric -- toronto, Ontario   3/10/2014
    Excellent item, very easy to setup and configure. My 10 year old son can setup this item and figure out the settings very easily. I would recommend this product to anyone who is looking to secure their home, and item or anything that you would like to monitor. Also because it can interface with any smartphone makes this even a more convenient way to keep an eye on those precious items.
    R Fuller -- manchester, CT   3/10/2014
    I've been using this sensor now for a couple of months and am very happy with the results.
