Temperature and humidity sensor is a sensor that detects the temperature and humidity of the surrounding environment and can sense subtle temperature and humidity changes and report them to the mobilephone APP, and users can view the current and historical temperature and humidity data on the mobilephone. It can be moved and placed at will or installed by sticking. Can be linked through thegateway to control other intelligent products, such as linkage with intelligent airconditioning, intelligent humidifier, intelligent freshair system and other equipments. Features: This intelligent temperature and humidity sensor combines functionality with innovative design, featuring concave edges that enhance aesthetics and practicality, creating visual depth and modernity. This design is user-friendly, easy to install, and comfortable to handle. Long lasting batterylife, equipped with a CR2032 button battery, can last for a year without the need for frequent battery replacement. When the battery is low, the sensor will push notifications through the app, so you can replace the battery in a timely manner. This sensor can cover a distance of 50m/164ft (without obstruction), allowing you to check temperature and humidity at any time at home. The sensors have high sensitivity and can quickly detect changes in temperature and humidity. When the temperature changes every 0.3 degrees Celsius or the humidity changes every 5%, the sensor can immediately capture these changes and present them in real-time in the app. Easy and convenient to install and remove. It can be linked with other intelligent devices to creates a more intelligent homelife.
