The MAX 10 NEEK has a humidity and temperature sensor (HDC1000) that provides excellent
measurement accuracy at very low power. The HDC1000 sensor is placed at board edge and away
from the heat source of MAX 10 NEEK so that user can make ambient temperature measurement
without heat interference from the heat source of MAX 10 NEEK.
Figure 3-32
shows the
connection of humidity and temperature sensor to MAX 10 FPGA.
Table 3-18
lists the humidity
and temperature sensor pin assignments.
Figure 3-32 shows the connections between the MAX 10 FPGA and humidity and temperature sensor.
