Therefore, if you want to get an accurate temperature reading of an object, make sure it lies completely in the field of view of the sensor. When the MLX90614 gives us the object temperature reading, it is the average temperature of all the objects present in the FOV of the sensor. FOV is a solid angle through which the sensor is sensitive to electromagnetic radiation. One important concept that comes up while learning the working of the infrared thermometer is the field of view of the sensor, also known as FOV. The ASSP processing unit convert this analog signal to filtered amplified signal which is then sent to the microcontroller. Thermopile serves the function of collecting the radiation in its field of view (FOV) which varies from version to version and then produces an electrical signal proportional to the radiation. The IR sensor module consists of an infrared thermopile detector and an ASSP (Signal conditioning application processor) unit. The processing units convert these analog signals to filtered amplified signals. Thermopile serves the function of collecting the radiation in its field view which varies from version to version. The IR sensor module consists of an IR thermopile detector and a signal ASSP processing unit. This radiation is then measured through the sensor converted to a digital signal and is communicated through the I2C bus to the microcontroller. It states that everybody radiates IR radiation proportional to its temperature. MLX90614 is a contactless IR temperature sensor that works on the Stefan Boltzmann principle.
