Temperature Sensors - NTC Thermistors

A temperature sensor is a device that measures the temperature of something, usually a physical object such as a piece of material, a person, or even the environment. NTC thermistors – or ‘Negative Temperature Coefficient’ thermistors – are a specific type of thermistor that are suitable for sensing temperature changes.

NTCG164QH334HT1

NTCG164QH334HT1 is a type of NTC thermistor capable of providing accurate digital temperature readings. It features a wide operating and temperature range, making it suitable for a variety of applications. It is also cheap and easy to implement, thanks to its low cost and simple design.

Application Field and Working Principle

NTCG164QH334HT1 can be used in different applications such as cooling and heating systems, automotive modules, home appliances monitoring, medical equipments, etc. It has a linear electrical resistance curve, which can be used to accurately measure temperature within its range. The resistance of the NTC thermistor decreases in a linear manner as the temperature increases, allowing an accurate output voltage that is proportional to the temperature.The working principle behind the NTC thermistor is that it has a temperature-sensitive material made from metal oxides such as manganese dioxide. This material is sandwiched between two electrodes, one of which is connected to the power source and the other to ground. As the temperature around the thermistor changes, the resistance of the material between the electrodes also changes, resulting in a changing voltage output. This voltage can then be read by a monitoring device such as a microcontroller and is used to measure the temperature.

Temperature Coefficient

The NTCG164QH334HT1 has a temperature coefficient of approximately 6 ~7%, meaning that its resistance changes by 6 ~ 7% for every 1 degree Celsius change in temperature. The thermistor is not affected by environmental factors such as humidity, pressure, and corrosion, allowing it to provide reliable and accurate readings over time. NTC thermistors are most often used in temperature control circuits, where the thermistor can sense temperature changes and then send a signal to a microcontroller. The microcontroller then takes the necessary action, such as switching on a cooling fan or a heater, depending on the temperature reading.

Conclusion

NTCG164QH334HT1 is an accurate and reliable NTC thermistor suitable for temperature sensing applications. Its linear electrical resistance curve and its temperature coefficient make it ideal for temperature control circuits. It is also extremely affordable and easy to implement. The NTC thermistor is a reliable and cost-effective temperature sensing solution, making it an ideal choice for a variety of applications.
