Working Principle

When the temperature of the object is higher t-han "absolute zero", that is -273 ℃, the object will radiate infrared radiation. In this case, the i-ntensity of infrared ray from different objects c-an be obtained by using infrared probe, and t-he temperature data can be displayed on the L-CD through the amplification circuit and ADC circuit.

Function Description

When using, the infrared probe should be aimed at the forehead of the human to obtain the tempe-rature. It is powered by a rechargeable and has a better battery life.
