Temperature is an important factor that influences many physical and biological systems. Therefore it is necessary to continuously monitor the temperature in order to ensure the safety of products and people and keep systems running efficiently. The MLX90621ESF-BAA-000-TU is an infrared thermopile array temperature sensor designed to measure the surface temperature of objects without requiring them to physically contact the sensor. It is a versatile solution for applications in consumer, industrial, and automotive products that require accurate temperature measurement.

The MLX90621ESF-BAA-000-TU temperature sensor is an analog and digital output temperature sensor. It uses a signal processing technique based on an array of thermopile sensors, which measure the net radiation flux of infrared radiation to accurately detect the temperature of objects. The thermopile array consists of 64 thermopiles which are distributed over a circular aperture with a 16x4 configuration. This device is designed to operate at temperatures as low as -20°C and as high as 100°C.

The MLX90621ESF-BAA-000-TU provides an accurate temperature measurement output signal, so it can be used in applications that require precise temperature measurements such as human thermal comfort, cooker overload detection, HVAC systems, and automotive applications. The output signal of the device can be either analogue or digital, depending on the user’s needs. Furthermore, the low-noise and low power consumption of the device make it an ideal solution for battery-operated applications.

The working principle of the MLX90621ESF-BAA-000-TU is based on the net radiation exchange of infrared radiation between the object and the thermopiles, which generates a differential voltage signal that is proportional to the temperature of the object. The thermopile array is read out with a constant current source and the data is collected in a 16x4 format so that differential thermopiles can be read out in the same temperature range. The output of the device can be either analogue or digital, depending on the user’s needs.

The MLX90621ESF-BAA-000-TU is well suited for a variety of temperature sensing applications, from consumer to industrial and automotive. It is designed to operate in temperatures ranging from -20°C to +100°C, making it ideal for a wide range of applications. Its low noise and low power consumption makes it an ideal choice for battery-operated applications. Furthermore, the device is capable of providing both analogue and digital output signals, which makes it a versatile solution for users who require accurate temperature measurements.
