Smart Toilet Nozzle Temperature Control Solution Based on NTC Temperature Sensor

The warm water washing function of smart toilet works by converting electrical energy into thermal energy through a built-in heating component, heating the washing water before it is output through the nozzle. To ensure that the nozzle water temperature of the smart toilet remains stable within the range set by user, the EXSENSE high-accuracy NTC temperature sensor is installed in the toilet‘s heating component. By monitoring the nozzle water temperature, it effectively improves the comfort and safety of user when using the warm water washing function of the smart toilet.

In the application scenario of smart toilet nozzle, the NTC temperature sensor is typically installed at the water outlet position, that is, at the water path node between the nozzle water inlet and the heating component. This position allows the EXSENSE temperature sensor to monitor the temperature of the heated water before it flows through the nozzle, so that the control unit can adjust the heating power before the water comes out, avoiding temperature errors caused by factors such as transmission distance. During the operation of the smart toilet, the NTC plays an important role in continuously monitoring the water temperature. The EXSENSE temperature sensor continuously transmits the real-time water temperature data to the control unit. If the set water temperature is 40℃, the NTC temperature sensor compares the real-time monitored water temperature with this value. Once the actual water temperature falls below 40℃, the control unit will immediately activate the heating component to raise the water temperature. Conversely, if the water temperature exceeds 40℃, the control unit will cut off the heating circuit to lower the water temperature, keeping it always stable within the preset range and ensuring user safety.

As the temperature feedback component of the samrt toilet nozzle, the EXSENSE NTC temperature sensor, with its excellent characteristics, becomes a key part of safety protection chain of the smart toilet:

1. High Accurate, Ensuring Precision Temperature Control and Safety Redundancy

The EXSENSE smart toilet NTC temperature sensor has an accuracy of ±1%, which can help stabilize the nozzle water temperature within a specified range, preventing risks of hot/cold stimulation or scalding due to large temperature differences. The high-accuracy feature also reduces the trouble of user having to repeatedly adjust the water temperature due to instability, enhancing the intelligence and convenience of the toilet and providing user with a truly comfortable and convenient warm water washing experience.

2. Rapid Response, Achieving Timely Adjustment and Safety Protection

The high sensitivity of the EXSENSE temperature sensor enables it to respond when the water temperature deviates from the preset value. Once the smart toilet control unit receives the signal, it immediately adjusts the heating component. The fast response feature of the NTC significantly reduces user’s waiting time and effectively improves the utilization efficiency of the smart toilet.
