As an essential sanitary ware in people's lives, the warm air drying function of smart toilet relies on high-precision temperature control. This process is inseparable from the temperature feedback of the EXSENSE Electronics’s NTC temperature sensor to help the smart toilet provide a more comfortable and safe user experience.

The smart toilet mainly uses the characteristics of the resistance value of the NTC temperature sensor to change exponentially with the temperature to ensure that the temperature of the warm air drying process is in the appropriate temperature range and avoid the user's discomfort. Specifically:

1. Monitoring and control of warm air temperature to ensure comfort and safety

The NTC temperature sensor is usually electrically connected to the main control module and heating module of the smart toilet. When the user uses the warm air drying function, NTC will monitor the temperature of the heating module in real time; If the temperature of the heating module is too high and exceeds the preset temperature threshold, the NTC temperature sensor will immediately transmit the temperature data to the main control module, and the main control module will immediately activate the protection mechanism to suspend the heating module to avoid users being burned due to excessive temperature. In addition, NTC temperature sensor is also used to monitor the temperature of the warm air. When the heating module heats the airflow, NTC will monitor the airflow temperature to keep it within a reasonable range and improve the user experience.

2. Early warning and protection of system failures to prolong the service life of smart toilet

In order to prevent extreme working conditions (such as short circuit, overload, etc.) during the operation of the smart toilet, when there is an abnormal change in the resistance value of the NTC temperature sensor during the temperature information collection process, the information will be immediately transmitted to the main control module, and the main control module will stop the heating module from working and send instructions to prompt the user to check. The overheating protection of the NTC temperature sensor can effectively avoid device damage and improve the durability of smart toilet.

The placement of the NTC temperature sensor excellently balances the comfort, safety and energy efficiency of the warm air drying system of smart toilet, and escorts the user during use. The reason why the NTC temperature sensor of EXSENSE Electronics can become an indispensable component in the warm air drying system of smart toilet is because of its high sensitivity and rapid response to temperature fluctuations, which reduces the hysteresis of the warm air drying process. In addition, the high accuracy of the NTC temperature sensor can assist the warm air drying system to improve the accuracy of temperature measurement and ensure the reliability of smart toilet.
