The Qingping Thermometer sensor for $27.99 on Amazon, works directly with HomeKit, so you pair it with Apple's Home app, and you can see exactly what the temperature is in whichever room you decide to place it in.
Plus, you can download Qingping's app from the App Store, where you'll have more detailed history data of the temperature in certain rooms, so you can try to adjust it if needed, especially if you have a newborn and they may feel like they're getting too warm.
So with this in mind, this sensor could be a great way of checking the heat on that summer day through its great e-ink display.
Check the humidity
Check the heat with the Qingping Thread Thermometer
If you're about to become a parent, the Qingping Thread Thermometer could be very useful to give you peace of mind about how hot your child's room can be as you're working away in another room.
But if you want to check it as you're all out to see family, remember that a HomeKit hub will be needed for those smart devices to be controlled outside of your home, which is where a HomePod or an Apple TV comes in.
With this sensor being 30% off the price, you may as well look into one just to see if it works for you and your home.
As Prime Day deals are changing almost every hour as it wraps up for another year, this price may not last long, so we advise you to snap this up before others get wind of this great deal.
