Temperature sensors are essential components in any system or component that is being designed today. The MIC184BMM-TR is an example of a temperature sensor that can be used for many applications due to its proven capabilities and reliable performance. It offers analog and digital outputs that are suitable for a wide variety of applications. This article will discuss the application field and working principle of this device.

The MIC184BMM-TR is a thermistor that can be used for both analog and digital temperature sensing applications. It is a four terminal semiconductor temperature sensor that offers a choice of both analog and digital output signal types. The device has four terminals, designated as 1, 2, 3 and 4, with two of them being either the positives or negatives of the two possible temperature sensing terminals. When two positive temperature sensing terminals are connected, the MIC184BMM-TR is designed to monitor temperatures on one side of the room and on two adjacent walls.

The MIC184BMM-TR provides an analog voltage output proportional to the ambient temperature, giving its user flexible programming and monitoring options without the need for additional components. It is a very reliable device, which allows it to be used in several applications, including environmental monitoring, machine monitoring, and industrial process control. It is also often used in HVAC systems for temperature control.

The working principle of the MIC184BMM-TR is based on the change in resistance of the semiconductor when the ambient temperature changes. It uses a negative temperature coefficient thermistor, meaning that it exhibits an increase in resistance with a decrease in temperature. As the temperature changes, the resistance changes, thus varying the voltage between the two positive terminals. This voltage change is proportional to the ambient temperature and is used to accurately measure temperature with the device.

The MIC184BMM-TR also offers two digital output signals. The first is an open collector signal, which is an active low signal that goes low when the temperature measured is equal to or greater than the set point. The second is a low signal that goes low when the measured temperature is lower than the set point. Both output signals can be used to monitor temperature changes and activate alarms.

The MIC184BMM-TR is a robust and reliable temperature sensor that is suitable for a variety of applications. Its ability to provide both analog and digital outputs in response to temperature changes makes it a reliable and versatile device. Its resistance-based working principle makes it easy to use, while its open collector and low signals output provide maximum flexibility for user applications.

In conclusion, the MIC184BMM-TR is a reliable and versatile temperature sensor with capabilities suitable for a wide variety of applications. Its ability to provide both analog and digital outputs in response to temperature changes makes it suitable for use in many applications. Its resistance-based working principle and open collector and low signals output make it relatively easy to use and allows for maximum flexibility and customization.
