Description

Technical Field

[0001] This utility model relates to the field of sensors, specifically to an indoor visual temperature and humidity sensor. Background Technology

[0002] Currently, monitoring indoor temperature and humidity data is extremely popular and necessary. Generally, indoor temperature and humidity monitoring devices include temperature and humidity sensors. A temperature and humidity sensor is a device or equipment that integrates a humidity sensor and a temperature sensor, capable of sensing the temperature and water vapor content in the environment and converting them into usable electrical signals. It is the "sensory organ" of the Internet of Things, allowing us to quantitatively understand the temperature and humidity conditions of our surroundings. Its core working principle is: capturing changes in temperature and humidity through internal sensitive elements, processing the data through circuitry, and finally outputting standardized readings in the form of digital or analog signals.

[0003] Currently, indoor temperature and humidity monitoring often employs a split design, where the sensor probe and display unit are separate. Users must view the data via a mobile app or a dedicated reader, which is cumbersome and lacks real-time performance. Some sensors with integrated displays suffer from bulky structures, high power consumption, and the need for frequent drilling and wiring during installation. For example, in one existing technology, the display module and sensor module are externally connected by a cable, which is prone to loosening and affects aesthetics. This invention aims to solve the above problems by providing a highly integrated, visually direct-reading, and easy-to-install all-in-one solution. Summary of the Invention
