This module measures the surface temperature by detecting infrared radiation energy and wavelength distribution. The IR temperature probe consists of an optical system, photoelectric detector, amplifier, signal processing and output module. The optical system collects the infrared radiation in its field of view and the infrared radiation energy is converted in to corresponding electrical signals when converging on the photoelectric detector. After being processed by the amplifier and signal processing circuit, the signal is converted in to a temperature value. The MLX90614 is self calibrating and has a low noise amplifier integrated in to the signal processing chip. The chip itself is a 17-bit ADC and DSP device, giving accurate and reliable results.
Gravity: I2C Non-contact IR Temperature Sensor (MLX90614-DCI), due to its small field of view (FOV = 5°), is more suitable for industrial applications where the detection distance can be longer. In general applications, you can use Gravity: I2C Non-contact IR Temperature Sensor For Arduino (MLX90614-DCC)
