Quality Inspection for Thermal Imaging Products - MSC Single-Point Infrared Temperature Measurement Module Used for Face Recognition Temperature Camera – Sunshine

Overview

MSC type single-point infrared temperature measurement module is a temperature measurement application based on single-point infrared sensor independently developed by the Sunshine Technologies. It is suitable for close range temperature measurement, which can detect the temperature of the object, the temperature of the body surface and so on. It has the characteristics of non-contact, quick response and convenient data conversion. Its temperature measurement method is similar to the forehead thermometers.
MSC module has two types, normal type is round and customized type square.

other close-range temperature measurement applications

Attentions:

1.YY-MSC type temperature measurement module is severely affected by the fluctuation of ambient temperature, it is forbidden to be tested by bare machine, or to be used in a thermal shock way, such as direct blowing at the air conditioning port.
2.When the shell installed and powered on, the module temperature can be measured accurately because the module needs to reach the thermal balance with the ambient temperature. When the thermal balance is reached, the ambient temperature is allowed to change slowly, such as the heating of the housing. According to experience, the heat balance time is 15~25 minutes (depending on the heating and insulation of different housing)..
3.The YY-MSC belongs to the point temperature close range temperature measurement module, the DS ratio is 1:1, the field angle is about 57 degrees. 8 cm. maximum temperature range If the DS ratio is satisfied and the uniform surface is opposite (the surface in its field of view angle is a uniform surface, such as black body), it has the following temperature variation characteristics:

The temperature characteristic can not be avoided because the infrared emissivity itself is attenuated by the influence of distance. If a customer does not use the Body Surface Temperature conversion inside the module, and their own research algorithm, need to focus on this feature.
