The Digital Infrared temperature sensor is a non-contact temperature measurement module which bases on MLX90615.Both the IR sensitive thermopile detector chip and the signal conditioning chip are integrated in the same package.This module communicates with Arduino using SMBus,up to 127 sensors can be read via common 2 wires.Thanks to the module's low noise amplifier, 16-bit ADC and powerful DSP unit, it can achieved a high accuracy of 1℃ over wide temperature rage and a high measurement resolution of 0.02℃. Features: 1、Wide Temperature Detecting Range 40 to 85°C for sensor temperature 40 to 115°C for object temperature 2、High accuracy of 1°C over wide temperature 3、Measurement resolution of 0.02°C 4、Embedded emissivity compensation 5、Power saving mode Documents: Please visit our wiki page for more info about this product.
