Embedded Sensor – NTC Temperature

This tutorial is about NTC Temperature sensor. Thermistors are temperature-sensing elements made of semiconductor material that have been sintered to display large changes in resistance in proportion to small changes in temperature. This resistance can be measured by using a small and measured direct current, or dc, passed through the thermistor in order to measure the voltage drop produced. These solid state temperature sensors actually act like electrical resistors that are temperature sensitive. That is where the name, a clear combination of the words thermal and resistor, comes from. Ametherm specializes in NTC, or negative temperature coefficient, thermistors.

NTC Temparature sensor

NTC (Negative Temperature Coefficient) thermistors, also known as NTC temperature sensors, measure temperature. They consist of semiconductor materials with a resistance that decreases as temperature increases. NTC thermistors exhibit a nonlinear resistance-temperature relationship, with resistance decreasing rapidly as temperature rises and vice versa.

These sensors are widely used in various applications due to their simplicity, accuracy, and low cost. Some common applications of NTC temperature sensors include:

  1. Temperature Sensing: NTC thermistors commonly measure temperature in electronic circuits, appliances, automotive systems, and industrial processes.
  2. Temperature Compensation: They stabilize the performance of electronic devices and components over a wide temperature range in temperature compensation circuits.
  3. HVAC (Heating, Ventilation, and Air Conditioning): NTC thermistors sense and control temperature in HVAC systems, aiding in regulating heating and cooling for optimal comfort and energy efficiency.
  4. Food and Beverage Industry: NTC temperature sensors monitor and control temperature during cooking, refrigeration, and transportation in food processing and storage applications.
