With the increasing popularity of outdoor activities, people's demand for portable heating sleeping bags is no longer limited to simple warm functions, but the pursuit of higher comfort and intelligence. Among them, NTC thermistor is a key temperature monitoring component in heating sleeping bag, which is of great significance for achieving accurate temperature control and improving user experience.

Traditional heating sleeping bags often use simple temperature control switches or thermostatic controllers, which cannot monitor the temperature changes inside the sleeping bag in real time, and can easily lead to problems such as too low, too high or uneven temperature. The NTC thermistor is placed in the portable heating sleeping bag mainly to monitor the internal temperature of the sleeping bag in real time and at the same time feed the temperature signal back to the control system. Through the accurate temperature measurement of NTC, the control system can adjust the working state of the heating module according to the predicted temperature range, ensuring that the internal temperature of the portable heating sleeping bag is always kept within the appropriate range. According to the user's usage, EXSENSE Electronics Technology Co., Ltd. recommends that NTC thermistors be installed (but not limited) in the following locations:

First, central area: monitor the temperature surrounding the user's body to ensure the temperature comfort of the main use area;

Second, edge area: set the thermistor at the edge or corner of the sleeping bag to monitor the temperature changes at these locations to prevent local overheating or overcooling;

Third key heating area: such as the bottom of the sleeping bag, the user's feet, other places where the user's body has more contact and is easy to accumulate heat, the accuracy of temperature control can be effectively improved through NTC.

Due to the soft nature of the portable heating sleeping bag, its internal PCB mostly uses FPC (Flexible Printed Circuit), EXSENSE Electronics recommends the use of CT series SMD type NTC thermistor, because of its encapsulated type of leadless and characteristic of small size, compared with the leaded type NTC is more suitable for the positioning of FPC’s thin and light integration. Moreover, the SMD type NTC can be better located close to the temperature monitoring area, which is conducive to the rapid real-time temperature monitoring. In addition to this, SMD type NTC thermistor also has the following advantages:

First, high accuracy, to ensure that the sleeping bag can obtain accurate temperature data during the working process, excellently complete the heating task;

Second, high stability, to ensure that the sleeping bag can be heated smoothly in any environment, to provide users with reliable and safe services.

The addition of SMD type NTC thermistors greatly improves the safety and comfort of portable heating sleeping bags, which not only meets their needs in different environmental conditions, but also provides an excellent user experience. By taking advantage of the temperature sensitivity of SMD type NTC thermistor, it can also continue to promote the development of future versatility of portable heating sleeping bags, and achieve a higher level of intelligence.
