Product details

If you have babies and children at home or family members who suffer from seasonal allergies, it is especially important to keep the room temperature and humidity at a comfortable level. The T51C, the new two-in-one thermometer and hygrometer from EZVIZ, can detect and visualize the status of your home environment and alert you with instant mobile notifications if something changes suddenly.

Simply stick the T51C to the wall with the included adhesive tape or place it on a table using the built-in stand. The T51C is designed for indoor use and is helpful wherever you need to know exactly how humid or warm it is. To protect your family in all rooms, you can purchase multiple T51C sensors and place them in different areas. It also helps improve respiratory health and prevent allergies or skin irritations.

Whenever the temperature or humidity drastically changes within a short period or falls outside the set range, you will receive an instant mobile notification. If you have an EZVIZ camera, you can connect the sensor to it to receive notifications along with a snapshot. The T51C is very energy-efficient and can operate for up to 365 days with the included replaceable battery cell.
