With the continuous development of smart home technology, smart furniture has gradually become widely popularized. Among them, smart faucets, as one of the representatives of the field of smart bathroom, are favored by many consumers with virtue of their convenience, safety and energy saving. To ensure that users have the best possible water experience, NTC temperature sensors play a pivotal role in smart faucets as "experts" in temperature sensing.

The smart faucet realizes real-time monitoring and precise control of water temperature with the assistance of NTC temperature sensor. Specifically:

First, the lead end of the NTC temperature sensor is electrically connected to the PCB of the smart faucet, and its temperature sensing head is placed in the water outlet pipeline, which can contact the water flow in order to monitor the actual water temperature. When the user turns on the faucet, the NTC temperature sensor immediately senses the change in water temperature, and its resistance value changes accordingly and transmits the signal to the built-in microprocessor. The microprocessor then adjusts the water temperature based on the received data and informs the user of the current water temperature via the display.

Second, in order to prevent users from being scalded due to excessive water temperature, the microprocessor of the smart faucet will preset a temperature threshold. The microprocessor will adjust the solenoid valve based on the temperature information fed back from the NTC temperature sensor,so as to control the mixing ratio of hot and cold water to keep the water temperature within the appropriate temperature range. In addition, most of the current smart faucets support water temperature setting, when the user selects the constant temperature value on the faucet display panel, the microprocessor will adjust the water temperature through the NTC temperature sensor to make it reach the user's desired temperature.

Therefore, with the assistance of NTC temperature sensor, the smart faucet can not only effectively avoid the risk of scalding caused by high water temperature, but also allow users to understand the water temperature status more intuitively, so as to better control the water use. Since the NTC temperature sensor needs to be in direct contact with the water source, it has very high requirements for sealing. EXSENSE Electronics Technology Co., Ltd. recommends the use of TS series NTC temperature sensor for smart faucet. This product uses pouring sealant to encapsulate the NTC thermistor in a metal shell, which can not only play a waterproof role, but also ensure that the temperature measurement of NTC during the operation of the smart faucet is not affected. And this NTC temperature sensor has high accuracy, ensuring the high accuracy of faucet water temperature detection and control data. Considering the differences in the design scheme of smart faucets on the market, EXSENSE Electronics supports customized service, we can customize NTC temperature sensor for smart faucet according to customer need.
