At just 2.2" W x 2.2" H x 0.9" D, it’s compact enough to tuck next to your potted plants, a nightstand in the nursery, or on a basement shelf without taking up valuable space. A standard credit card is 2.125" x 3.37".

It runs on three (3) standard AAA batteries (not included). Because there are no messy power cords, you have the total freedom to place it on a shelf or mount it on a wall anywhere in your home—even in spots without an outlet.

Because it’s completely wire-free, you can place it anywhere you want to monitor comfort. Simply set it on a flat surface or use the integrated keyhole hanger to mount it on a wall.

Our customers love using them in:

• Nurseries and bedrooms to ensure a comfortable sleep environment.
• Bathrooms, basements and attics to monitor for excess humidity and prevent mold.
• Plant rooms and greenhouses to dial in the perfect growing conditions.
• Storage areas to protect guitars, cigars, or collectibles.

Pro-Tip for accuracy: For the most accurate readings, place the monitor out of direct sunlight and away from heating vents, humidifiers, or drafty windows.

Not at all! The monitor features a crisp, built-in screen and a color-coded Comfort Meter so you can see your room’s conditions at a glance. However, connecting it to your home Wi-Fi and the free AcuRite NOW app unlocks its superpower: the ability to check those readings from anywhere in the world right on your phone.

You never have to guess or constantly check the screen. With the free AcuRite NOW app, you can easily set custom high and low thresholds for both temperature and humidity. If conditions ever fall outside your preferred zone, you’ll receive an instant push notification on your phone—letting you take action before your basement gets too damp, your plants dry out, or the nursery gets too cold.

A standard thermometer or humidity monitor only helps you if you are standing right in front of it. If you are at work or asleep, a basic gauge can't tell you that your bathroom is getting damp or your nursery is freezing.

This monitor acts as a 24/7 smart assistant for your home’s environment. Here are the three main differences:

• Remote Access: Instead of having to walk into the room to check the conditions, you can see real-time data from anywhere in the world using the AcuRite NOW app on your phone.
• Proactive Alerts: A regular gauge requires you to notice a problem. This monitor actively warns you by sending push notifications to your phone the second your room gets too hot, cold, dry, or humid.
• The Comfort Meter: Standard gauges just give you raw numbers, leaving you to guess if 62% humidity is actually bad. This device features a color-coded comfort scale that instantly tells you if the air is "Dry," "Comfortable," or "Wet," so you know exactly when to turn on a humidifier or dehumidifier.

By combining the simplicity of a glanceable screen with the power of a smart-home app, you get total peace of mind for less than $25.
