Sensors are increasingly applied to various fields of social development and human life, such as industrial automation, robotics, medical diagnosis, household appliances, etc. In recent years, the global sensor industry has developed rapidly. Sensors not only enter people's daily work and family life, but also have been widely used in various sectors of the national economy. From the initial manufacturing of machinery and equipment, agricultural production, to electrical appliances, scientific instruments and meters, medical and health, communication electronics and automobiles, until the current smart home. Sensors are everywhere. In recent years, people's requirements for the quality of life have become higher and higher, which has led to an increasing demand for smart homes. The key parts of the smart home are mainly made of sensors, which naturally increases the sales of sensors. Sensors have become the touchstone in the wearable device industry chain, and a field with strong opportunities in the hardware industry chain. Taking Google Glass as an example, it has built-in more than 10 kinds of sensors, including the application of gyroscope sensor, acceleration sensor, magnetic sensor, linear acceleration and other sensors, which allows Google Glass to realize some functions that cannot be realized by traditional terminals, such as Users can take pictures with just a blink of an eye. All these intelligent operations are high-tech applications of source sensors. In the future, more sensor products may be fully applied in people's lives, and sensor technology will be further developed intelligently. In the future, sensors will perfectly fit with intelligent technology, and step by step towards a perfect intelligent life, it will not only subvert our vision, but also facilitate all aspects of our life and daily work.

We know that the safety threat of electric vehicles is not only the risk that may be caused by the defects of intelligent algorithm and functional design. One of the most important reasons for people to fear the accident of electric vehicles is the threat and injury caused by the explosion of the battery. too serious. For example, when the vehicle is in a static state, problems such as battery overcharge, short circuit, and liquid leakage caused by imperfect battery system management, incompatible communication, and communication barriers with charging equipment cannot be monitored and alarmed in advance, resulting in thermal runaway, spontaneous combustion, and fire. Such situations require the management of battery safety through a battery management system (BMS). The battery management system uses the CAN communication protocol and real-time dual ECU multi-level monitoring, which makes the communication between the charging equipment and the battery management system smooth and coordinated to ensure the safety of the battery. During the charging process, if the three links of battery cell, BMS, and sensor do not cooperate well, spontaneous combustion may occur. For the dynamic temperature change of battery charging and discharging, first of all, the pack design of the battery itself is very important, and it is necessary to ensure the heat dissipation and reliability of the battery, and secondly, the constant temperature thermal management technology of the battery pack of the electric vehicle can control the temperature of the battery cell more stably at a high efficiency, safe temperature range.

In today's society, temperature sensors can be said to be ubiquitous. Air conditioning systems, refrigerators, rice cookers, electric fans and other home appliances, as well as handheld high-speed and high-efficiency computers and electronic equipment, all need to provide temperature sensing functions. Taking a computer as an example, the faster the CPU runs, the more heat it dissipates. In order to prevent the computer system from being damaged by overheating, the system must strengthen the overheating protection function. On the other hand, if the system performs high-speed wireless transmission, it is necessary to provide temperature compensation due to frequency shift. The traditional temperature sensor method is limited by its package size, linear performance or accuracy, but the current temperature sensor chip not only has low power consumption and high accuracy, but also has better linear performance than traditional temperature sensors. The most important point It is easy to use. The chip development of temperature sensor has four directions: analog, digital, remote diode, and system monitor. The analog output temperature sensor is suitable for use in cellular mobile phones. Since these types of phones are very sensitive to temperature, over or under temperature protection is very important.

The temperature transmitter technology has been very mature, and it is very common in various factories. The temperature transmitter is often used in conjunction with some instruments, and there are often some small faults during the supporting use. The more common faults and solutions are as follows. First, the output of the transmitter does not change when the temperature of the measured medium increases or decreases. Most of these cases are caused by the sealing of the temperature transmitter. It may be because the temperature transmitter is not sealed well or is careless during welding. The sensor is welded with a small hole, which generally requires replacing the transmitter housing to solve. Second, the output signal is unstable. This reason is the reason of the temperature source, which is an unstable temperature. If the instrument display is unstable, it is the reason that the anti-interference ability of the instrument is not strong. Third, the output error of the transmitter is large, and there are many reasons for this situation. It may be that the resistance wire of the selected temperature transmitter is not correct, resulting in a wrong range, or it may be that the transmitter is not calibrated well when it leaves the factory.

TemperatureSensor & HVAC Sensors Insights — Precision Matters in Smart HVAC Real Data: Comparing ±0.3 °C vs ±1.0 °C Sensors in Energy-Intensive Buildings 1. Temperature Accuracy: The Invisible Backbone of Indoor Comfort Central air conditioning in homes and businesses offers comfort that goes beyond just temperature. This sentence discusses how consistently and accurately someone keeps the environment. The human body can sense temperature changes as small as 0.3 °C. This is especially true in places like offices, hotels, and luxury homes. When a thermostat or sensor is off by 1.0 °C, the system overreacts — this causes uncomfortable temperature changes, wastes energy, and leaves people unhappy. That's why the difference between a ±1.0 °C sensor and a ±0.3 °C sensor is important — crucial for any serious HVAC or Smart HVAC system. 2. Homogenized HVAC Market Needs Real Differentiation Today, many HVAC systems offer similar core features — heating, cooling, and basic automation. In a crowded and similar industry, what makes a system stand out is what it senses — including the accuracy of the TemperatureSensor. High-precision sensors, often underestimated, directly impact system responsiveness, energy usage, and long-term performance. The following real-world examples highlight the performance gap. Real-World Case Studies: Performance Gains from Precision Sensors Case Scenario What Changed After Upgrading to ±0.3 °C Sensors Residential Villa – Vancouver, Canada High-end villa installation 31% reduction in climate-related complaints; lower system cycling frequency; homeowner comfort rated 4.7/5 Hospital HVAC Retrofit – Seoul, South Korea Operating rooms / medical-grade HVAC Achieved ±0.2 °C environment stability; HVAC fluctuations reduced by 42%; better compliance with medical-grade standards Office Complex – Munich, Germany Commercial office HVAC ±1.0 °C → ±0.3 °C: 9.5% annual energy savings (~€18,000); improved employee productivity; HVAC downtime reduced by 17% 5-Star Hotel Chain – Singapore Guest rooms & hospitality HVAC Improved “room climate” review scores; lower chiller workload during peak months; ~US $11,000 annual savings per property Industry reports show that a misreading of just 0.5 °C can cause energy overuse — up to 8% — in energy-intensive zones like commercial kitchens and data centers.

These thermistors have tighter tolerance, lower drift, and strong packaging. They are made for tough sectors like EV battery systems, HVAC, and IoT.Explore features, datasheet support, and application guidance below. 1. The Role of 10k NTC Thermistors in Modern Temperature Sensing In 2025, 10k NTC thermistors are still a top choice for designers. They offer great sensitivity, cost-effectiveness, and compatibility with electronic systems.The “10k” refers to the nominal resistance at 25 °C—i.e. R25 = 10,000 Ω. This base point allows standardization across many applications.  NTC thermistors are negative temperature coefficient resistors: as temperature increases, resistance decreases.This behavior is sharper than metals or silicon resistors. It makes them very sensitive in many thermal monitoring tasks.  2. R-T Behavior & Modeling with Public Data A widely used reference is the Labfacility 10k NTC table (B25/85 = 3977 K), which maps temperature to resistance across –40 °C to +125 °C. Temperature (°C) Resistance (kΩ) –40 336.479 0 32.65 (approx) 25 10.00 50 3.747 90 0.916 This nonlinear response is typically modeled via the B-parameter or the Steinhart–Hart equation. For instance, Electronics Tutorials uses B = 3455 for a 10k NTC spanning 25 °C to 100 °C. ([electronics-tutorials.ws] 3. Critical Parameter Considerations 3.1 Tolerance & Beta Stability Common tolerances include ±1 %, ±2 %, ±5 %. For example, Amwei’s 10k device lists R25 ±1 % with Beta B25/85 = 3435 K ±1 %. [amwei.com] Stability of the Beta parameter over time and environmental cycling is crucial for long-term accuracy. 3.2 Thermal Time Constant & Self-Heating The thermal time constant for many 10k NTC units is around 10–15 seconds. For instance, Handson’s 10k-3950 spec sheet lists 15 s.Meanwhile, self-heating (due to the measuring current) can artificially raise the sensor’s temperature and distort readings. Designers must restrict excitation current to limit th...
