Applications and Attentions

Applications:

forehead temperature measurement

palm temperature measurement

other close-range temperature measurement applications

Attentions:

1.   YY-MSE 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-MSE 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 blackbody), 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.
