With the improvement of people's quality of life, the temperature requirements for drinks are getting higher and higher. Whether it is brewing milk powder for infants, decocting Chinese medicine for patients, or brewing tea/coffee for guests, the water temperature needs to be accurately monitored to ensure that the temperature is suitable and will not cause burns. In order to meet the portable needs of consumers, liquid thermometer came into being, and its accurate temperature measurement is inseparable from the help of NTC thermistor.

At present, most of the thermometers on the market are temperature measured on the cup wall, due to different cups have different thickness of the cup wall, which is easy to mislead the thermometer and reduce the accuracy of the measurement data. The liquid thermometer is placed directly in the liquid and the temperature is measured by the NTC thermistor in the temperature collection point to obtain real-time temperature information effectively. Specifically, the NTC is set in the temperature collection head of the liquid thermometer and electrically connected to its microcontroller, switch, Bluetooth Low Energy chip and other components. When the switch is activated, the thermistor begins to monitor the temperature of the liquid, and the collected temperature information is transmitted to the microcontroller instantly. Users can wirelessly connect with the liquid thermometer through the Bluetooth function of mobile terminals (mobile phone, smart watch, etc.), and can know the temperature of the measured liquid immediately. The reason why NTC thermistors are used in liquid thermometers:

First, the temperature measurement process is stable and not affected by environment, airflow and other factors easily;

Second, the temperature difference with the liquid is reduced as much as possible to make the measurement accuracy higher.

In order to make the temperature measurement process of the liquid thermometer more efficient and improve the user experience, the IT series miniature thermistor of EXSENSE Electronics Technology Co., Ltd. are generally selected for temperature monitoring. With an accuracy of ±0.5%, this NTC assists the liquid thermometer to measure the temperature of the liquid accurately and reduce the measurement error. Its small size can help liquid thermometer to develop in the direction of miniaturization and portability. Moreover, IT series miniature NTC thermistor of EXSENSE Electronics has great consistency,which can maintain stable electrical performance in various environments.
