Today, a vast array of temperature sensors are available for a multitude of applications, from industrial to scientific. Many of these temperature sensors employ analog or digital output interfaces, making them suitable for a variety of uses. One of the most popular temperature sensors with digital output is the MLX90614KSF-AAA-000-TU, an infrared (IR) non-contact temperature sensor from Melexis. This sensor features an I2C output and can be used to measure ambient air temperature as well as the surface temperature of an object. In this article, we will look at the application fields and the working principle of the MLX90614KSF-AAA-000-TU.

The MLX90614KSF-AAA-000-TU is a single-zone infrared thermometer. It employs a thermopile sensor which measures the average surface temperature of the object in the field of view of the device without making physical contact. The thermopile sensor collects the mid-wave infrared energy emitted by the object in its field of view. This energy is then converted to a temperature reading. This makes the MLX90614KSF-AAA-000-TU ideal for measuring surface temperature from a distance and in situations where physical contact is not an option. This infrared thermometer is also suitable for medical applications such as detecting fevers in a contactless manner.

The MLX90614KSF-AAA-000-TU has a resolution of 0.02°C and an accuracy of ± 0.5°C. It operates from a voltage range of 4.75 to 5.25V and draws only 0.5mA of current at maximum resolution and accuracy. It also has a built-in temperature compensation system that compensates for the effect of self-heating of the device.

The MLX90614KSF-AAA-000-TU is a two-wire interface temperature sensor with integrated electronics. The device includes an internal EEPROM that stores the calibration parameters for optimized temperature readings. It also has an integrated demodulator and signal conditioning circuitry that allows it to interface with the I2C bus. Additionally, the device includes a 12-bit analog-to-digital converter that allows the measured temperature data to be read as a digital code on the I2C bus.

The MLX90614KSF-AAA-000-TU is a versatile temperature sensor that can be used in a variety of applications. One of the most common applications is in building automation, where the device can be used to control heating, ventilation and air conditioning (HVAC) systems. It is also suitable for use in motion detection systems, window and door open/close detection systems and occupancy detection systems. This infrared thermometer is also suitable for medical applications such as monitoring the temperature of patients or animals without physical contact.

The working principle of the MLX90614KSF-AAA-000-TU is based on the infrared radiation emitted by the object in its field of view. This radiation is collected by the thermopile sensor and then converted to a temperature reading. The reading is then further processed by the device\'s on-board electronics and output as a digital code on the I2C bus.

The MLX90614KSF-AAA-000-TU is a versatile temperature sensor with multiple applications in both industrial and scientific fields. It is a contactless thermometer that can accurately measure the surface temperature from a distance. The device has an integrated EEPROM for storing the calibration parameters and a 12-bit analog-to-digital converter that allows temperature data to be read as a digital code on the I2C bus. The integrated demodulator and signal conditioning circuitry make the device suitable for a variety of applications.
