Frequent use of temperature detection sensors in life

Temperature detection is the basis of all advanced forms of temperature control and compensation. The temperature detection circuit itself monitors the ambient temperature. Then, it can notify the system of the actual temperature or, if the detection circuit is smarter, when a temperature control event occurs. When a certain high temperature threshold is exceeded, the system can take preventive measures to lower the temperature.
  
Temperature sensors play an important role in many applications. For example, maintaining a specific temperature is essential for equipment used to manufacture medical drugs, heat liquids, or clean other equipment; for these applications, the responsiveness and accuracy of the detection circuit is essential for quality control Vital.
  
However, more frequently, temperature detection is part of the preventive reliability, for example, although the device may not actually perform any high-temperature activities, the system itself may be at risk of overheating. This risk comes from specific external factors, such as harsh operating environments or internal factors, such as self-heating of electronic equipment. By detecting when overheating occurs, the system can take preventive measures. In these cases, the temperature detection circuit must be reliable within the expected operating temperature range of the application.
