Abstract

The invention relates to a non-contact temperature measurement device, a temperature measurement module thereof and electronic equipment. The temperature measurement module comprises a substrate; a heating resistor and a temperature-sensitive resistor which are arranged on the substrate, the heating resistor is in contact with the temperature-sensitive resistor, the temperature-sensitive resistor is used for receiving an optical signal radiated by a target to be measured and generating a first electric signal according to the optical signal, the first electric signal is used for generating a first control signal for controlling the heating resistor to heat, and the heating resistor is used for heating; so that a temperature measurement module is in a constant temperature state, wherein the first control signal is used for determining the temperature of the target to-be-measured. According to the non-contact temperature measuring device, the heating resistor and the temperature-sensitive resistor which are in contact are utilized, the temperature measurement module is controlled to be in a constant-temperature state through a closed loop for temperature measurement, and a far infrared temperature measuring device is small in size and convenient to package while the temperature measurement accuracy is guaranteed. The heat capacity of the far infrared temperature measuring device is small due to the small size, so that the power consumption of the device is effectively reduced.

Description

Technical field [0001] In particular, in the field of temperature measurement technology, and more particularly to a non-contact temperature measuring device, a temperature measurement module and an electronic device. Background technique [0002] Radiation temperature is a typical non-contact temperature measuring method, which is to vary with temperature changes with temperature in the temperature of the object. The temperature of the target to be tested is received by the sensor in the form of radiation, generating an electrical signal output corresponding to the intensity of the radiation, and the temperature value of the target to be tested is measured after the processor is processed. Non-contact temperature measurement sensors have a wide range of applications in industrial, healthy and medical fields. Non-contact temperature measurement sensors typically use thermal piles, but thermopiles have a large package volume, high heat capacity, high power consumption, and high pr...
