White goods
In the scenario of large household appliances in daily life, intelligent sensor products have various functions such as automatic and precise collection, storage, and judgment of temperature and humidity data in the environment. Their rich data collection capabilities enable automatic control through data judgment to regulate their internal behavior (switching, alarm, forming data logs), upgrading intelligent sensors to the core hardware of the sensing layer. Intelligent temperature and humidity sensors promote the upgrading of white goods from "passive execution" to "active sensing, adaptive adjustment" as "intelligent managers".

Smart electricity meter
In the power supply connection components of single-phase and three-phase meters, if the temperature of a certain terminal is greater than the set alarm threshold and the duration is greater than the set overheating judgment delay time, this condition is terminal seat overheating.

When encountering a single-phase meter with 4 terminals, the local and remote 1+4 temperature measurement chip GXTR304 is used. If there are 8 terminals for a three-phase meter, the local and remote 1+8 temperature measurement chip GXTR308 is used to provide multiple terminal seat temperature monitoring functions with one chip. Thresholds are set and monitored for terminal seat temperature, terminal seat temperature minute variation, and terminal seat temperature imbalance.

BMS
In BMS (Battery Management System), the core function of humidity sensors is to capture real-time changes in humidity inside the battery pack, and their monitoring data is directly related to battery safety and lifespan. When the humidity exceeds the standard, it will accelerate the corrosion of the internal electrodes of the battery, the decomposition of the electrolyte, and thus cause capacity decay and internal resistance increase, ultimately leading to battery aging or failure. Therefore, strict humidity thresholds are usually set for battery packs in the industry (such as most power battery packs requiring internal relative humidity to be below 60%). Once the sensor detects that the humidity exceeds the limit, the BMS will immediately trigger an alert and even activate protection mechanisms (such as cutting off charging and limiting discharging) to avoid safety risks.

Medical device
Temperature and humidity sensors are used in medical devices such as ventilators and oxygen concentrators for daily humidity control. Ventilators require precise control of air temperature and humidity, simulating the natural breathing environment of the human body to prevent respiratory damage caused by low humidity, as well as to prevent condensation water backflow or bacterial growth caused by high humidity. Oxygen concentrators generally rely on molecular sieves to increase the concentration of oxygen. If the humidity is too high, water molecules will condense on the molecular sieve, reducing the concentration of oxygen production and the lifespan of the molecular sieve. Therefore, it is necessary to detect the humidity and control it properly.
