Temperature and humidity sensors are usually installed in areas with high humidity or narrow space. These areas are usually dark. In the absence of lighting, it is difficult to accurately locate the installation position of the sensor. If the temperature and humidity sensor fails, maintenance will be more difficult. There are many types of temperature and humidity sensors, but most of the sensors cannot transmit data to the monitoring center in time, and the measurement accuracy and reliability are low, which brings some inconvenience to people's use. According to the problems found in the investigation, some corresponding adjustments have been made, and adjustments have been made one by one in terms of appearance design, structural design, and hand board production. In terms of product design, this temperature and humidity sensor is small in size, stable in performance, simple and pure white in color, and the material is carefully adjusted. Its shell technology is excellent and gives people a good sense of operation experience as a whole. This temperature and humidity sensor is widely used in various fields of production and life and can be used in living rooms, bedrooms, study rooms, offices and other indoor environments. The temperature and humidity sensor also has a wireless function. The wireless temperature and humidity sensor design is very sensitive to the temperature control and humidity detection of the space. It can intuitively feed back various monitoring data to the user through wireless technology, so that the user can understand the current temperature and humidity of the home or a certain environmental space, and improve the quality of life. The temperature and humidity sensor allows users to control the corresponding ambient temperature on the basis of understanding the temperature and humidity, it is more conducive to people's health.
