There are quite a number of different versions (i.e. Calculations to compensate the temperature for lower emissivity can be used, if you know the emissivity of the surface you are measuring. Metals such as aluminum have low emissivity and will tend to read lower IR temperatures. IR temperature readings can vary depending on the emissivity of the target. ![]() The distance to the object does not change the temperature reading as long as the object fills the sensor’s field of view (beam width). IR thermometers measure the IR surface temperature of an object. ![]() ![]() It has an I2C or PWM interface and will operate off of 3.3V. It contains an internal 17-bit ADC and a custom DSP chip to achieve high accuracy and resolution. The Melexis MLX90614 is an infrared thermometer designed for non-contact temperature sensing.
