Application Field

The MLX90614KSF-AAA-000-SP is an ideal temperature sensing component for a variety of applications, including temperature monitoring in medical equipment, monitoring environmental conditions, measuring temperature in the automotive and HVAC (heating, ventilation, and air conditioning) industries, as well as in consumer electronics.This device offers temperature measurements in the range of -20 to +125°C, with an accuracy of ±2°C and a resolution of 0.02°C. This makes it suitable for use in a wide range of applications, as it can detect and measure small temperature changes. Additionally, the device uses an advanced thermal conductivity heat sensing element that allows for fast and accurate temperature measurements.

Working Principle

The MLX90614KSF-AAA-000-SP is a temperature sensor that uses a thermistor to measure the temperature of a surface or object. A thermistor is a semiconductor device that is sensitive to temperature changes; it has a resistor that changes its resistance with temperature. The thermistor is connected to a voltage source, and when a temperature difference between the object and ambient air is detected, the thermistor’s resistance changes based on that difference. This change in resistance is then translated into a voltage signal which is then transmitted to the device’s interface.The signal is then processed and output to the user interface, which can be either an analog output (such as voltage or current) or a digital output (such as SSI or SPI). The device also has a built-in ambient temperature sensor that can be used to measure the environment’s temperature. The device is also protected from overvoltage and has an alarm output for out of limit temperature measurements.

Conclusion

The MLX90614KSF-AAA-000-SP is an advanced temperature sensing component designed for a wide range of applications. It uses a thermistor to measure the temperature of a surface or object, and an ambient temperature sensor to measure the environment’s temperature. The device is capable of providing accurate temperature measurements over a wide range and can be connected to either an analog output or digital output interface. This makes the MLX90614KSF-AAA-000-SP an ideal temperature sensing component for a variety of applications.
