It also notifies you when something may happen to your baby, with lights and sounds notifications from the Base Station, as well as mobile notifications on your smartphone, anytime, anywhere. - TRACKS YOUR BABY'S ABDOMINAL MOVEMENT WITH REAL-TIME ALERTS: Unlike traditional baby video cameras or audio monitors, the Sense-U Smart Baby Monitor 3 tracks your baby's abdominal movement during sleep and notifies you after 15 seconds of no abdominal movement, anytime, anywhere. - GET NOTIFIED WHEN YOUR BABY ROLLS OVER TO SLEEP ON STOMACH: For healthy newborn babies, it is always recommended to place them on their backs to sleep and not on their stomachs.

Sense-U baby monitor 2 tracks the baby's skin temperature. The wearing directions of the two baby sensors are different. If you have any questions, please don't hesitate to let me know. Regards, Alayna@Sense-U **Q: Is there a certain distances that the baby monitor has to be away from the base for it not to work I can't go more that 20 ft without it say it's disc** A: Dear customer, The Sense-U Smart Baby Monitor uses Low Energy Bluetooth(BT4.0) which has a communication distance of up to 50 feet (15 meters). Notice that these are intended ranges. This communication distance could be affected by walls or roofs in between. And if the base station's light is a flashing GREEN circle, but the app shows no data, please refresh the app by tapping the On/Off button in the app or switching the app between foreground and background to load the data. It doesn't mean the device is disconnected from the base station. It might be because the app can't upload the data successfully. Any other questions, please feel free to ask. Best Regards, Alice.C@Sense-U **Q: Does this work even if you are waiting for the umbilical cord to fall off?** A: Dear Customer, The Sense-U Baby Monitor still works. First, you can turn the Rollover Alert off because the newborn can't roll over yet. Then please avoid the belly button and wear the baby sensor. If you have any questions, please don't hesitate to let me know. Sincerely, Alayna@Sense-U **Q: Can you use this monitor without the base? For example while we are in a car or something…** A: Dear Customer, Yes, the baby sensor can connect via Bluetooth with your phone when you go out. The communication distance is up to 50 feet (15 meters) in open space. Brick walls or obstacles in between may affect the distance dramatically. Before you do that, you have to delete the base station from the APP and pair the baby sensor with your phone directly. Best Regards,  Relo@Sense-U ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great peace of mind! *by L***O on Reviewed in the United States on January 12, 2024* Review by my husband:The Sense-U monitor was something that my wife had found and researched. We ended up purchasing after finding out a certain “bird” baby monitor no longer monitored what they said.The Sense-U monitor measures abdominal movement and feeling temperature. The parameters are preset, but through the app you can change the parameters to what you feel comfortable with. Then if either of the values fall out of range, an alarm sounds on your phone and the base station.I like that the base station is small and unobtrusive. The base lights up when the alarm goes off. The LED is bright enough to see from various angles. And the alarm is quite loud, which for a heavy sleeper, is great for me.The monitor itself is small flat circle that slides onto the front of the diaper with a small pinhole size LED. The monitor stays on fairly well considering. The only times it comes off is when our baby is fussy and kicking their feet a lot. The gyro inside the monitor is to my surprise very responsive.The app is user friendly and intuitive. Easy to set up the units with instructions to connect to Wifi and pair the base station to the monitor. The app has various tabs. The main tab is split into the monitor data and the base station data. The monitor data shows what position the baby is in regards to the monitor with an cute image of a baby. It also shows the abdominal movements and feeling temperature clearly. The bases station shows room temp and humidity levels. There is a tab that tracks the alerts of when the measured metrics fall out of the assigned parameters. There is an optional subscription service for the app that adds more to the app, but I find that the app as it is already does what we need it for.There have been times when I would get frustrated or not understand something about the monitor. I found that the help desk section of the product’s website truly is helpful and assisted me in understanding what it is doing (or not doing) and how to remedy it. All in all we both quite like this system and the peace of mind it gives my wife is worth every penny to me! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Helps relieve anxiety *by S***H on Reviewed in the United States on May 14, 2023* I’m a first time mom and overwhelmingly worried about every little thing. Constantly. I wanted the Owlet monitor but I couldn’t justify the price and my son has a unilateral talipes (clubfoot) that requires him to wear a cast and boots on his foot, so the Owlet wouldn’t have worked anyway. I read tons and tons of reviews for this product as well as similar ones and ultimately decided on this one. Within the first night I felt extremely relieved and slept better myself. It takes a little while to figure out how to set it up and use it, but then it’s easy. I would typically stare at the baby monitor or go up to the bassinet constantly throughout the night to ensure he was breathing. Now, with this, I don’t of that at all. I simply open the app and see the stats and then go back to sleep. Of course it’s not foolproof, but it does ease my mind. Also he doesn’t even seem to notice it’s there on his diaper whatsoever. The only drawback is that the Bluetooth doesn’t reach that far. For example, since he currently sleeps in a bassinet in our room, the device is easily connected to the base and works flawlessly. But, once we have to move him into his crib, down the hall, the device no longer connects to the base. Even though this is not a far distance whatsoever. So, I’m not sure what we will do once he’s moved in there. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Works good, but notifications are a bit more delayed than ideal *by L***S on Reviewed in the United States on September 14, 2024* Overall I’m blown away with how well the little sensor picks up both breathing and baby position. I bought this when my 5 month old started flipping over to her stomach when sleeping to give us peace of mind that we could sleep, but still know if she flipped and could right her before she suffocated.When you have the app open, it damn near instantly shows the position change from back to stomach, however the notification, both in app, and on the base station are delayed 45-60 seconds consistently. I contacted support and they said that’s fairly normal, but could be internet latency. Doesn’t make any sense since the darn app itself shows up immediately. I’m guessing there’s a setting you cannot change for how long it waits to beep / notify so you don’t get false alerts for continuous rolls or quick flips.If they could fix this, or allow you to change it, it would be an easy 5 star ## Frequently Bought Together - Sense-U Smart Baby Movement Monitor 3 - Tracks Baby's Abdominal Movement, Sleep Position, Temperature, with Real-time Alerts, Anytime, Anywhere - Dr. Brown's All-in-One Sterilizer and Dryer for Baby Bottles, Parts & Other Newborn Essentials - Sense-U Smart 2K Video Baby Monitor, Pan/Tilt, Person/Baby Crying/Motion Detection, 2-Way Talk, Night Vision, Background Audio, No Monthly Fee (Compatible with Smart Baby Monitor) --- ## 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.jp/products/398210587-sense-u-smart-baby-movement-monitor-3-tracks-babys-abdominal](https://www.desertcart.jp/products/398210587-sense-u-smart-baby-movement-monitor-3-tracks-babys-abdominal) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-22*
