NTC thermistors are temperature sensitive resistors that change their resistance with temperature. This phenomenon is called the Peltier effect and is used in many applications to measure temperature. The PW502J2 is a temperature sensor that uses NTC thermistors to measure temperature. As such, it has a wide range of applications in temperature monitoring and control.

The PW502J2, in particular, is designed to measure temperature over a wide range of temperatures and is ideal for applications in industrial settings. It detects temperatures from -50°C (-58°F) to +150°C (+302°F). It has a highly reliable accuracy (+/-0.5°C) and a wide range of features including three measuring ranges, a large memory capacity, and a low power consumption.

In terms of its basic working principle, the NTC thermistor works by changing its resistance when exposed to changes in temperature. When the temperature rises, the thermistor\'s resistance decreases and vice versa. The PW502J2 has an NTC thermistor device as its main component, connected to a bridge circuit, which is connected to the analog converter circuit. When a temperature signal is received, the bridge circuit will transfer the temperature signal to the analog converter, which determines the temperature and translates it into an electrical signal which will be received by the microcontroller and will then be processed to display the temperature.

The PW502J2 is a versatile temperature sensor used in industrial settings. Its ability to measure temperatures over a wide range makes it an ideal sensor for applications such as medical equipment and industrial process control. It has a light and compact design, ensuring ease of use in any installation and it is simple to configure and use.

The PW502J2 is just one example of an NTC thermistor based temperature sensor. There are many different types of thermistors out there, used for different purposes and applications. Overall, NTC thermistors offer an efficient and reliable way to measure temperature and their use is becoming increasingly popular in industrial settings.
