Measuring Ambient Temperature
Donal McNamara [email@example.com]
Many designers want to measure the ambient temperature, not that of the PCB. To do this, they must prevent the heat sources on the PCB from affecting the temperature sensor by using the layout shown in figure 1:
Figure 1. Correct Layout for Measuring Ambient Temperature
following these tips, the temperature sensor will not be
affected by the heat dissipated by the main heat source, and
will accurately monitor ambient temperature.
