Ambient Light Sensor
The MAX 10 Plus has a Light-to-Digital Ambient Light Sensor (APDS-9301) that converts light
intensity to digital signal output capable of I2C interface. with I2C digital interface and
programmable-event interrupt output. The digital output of APDS-9301 will be input to the MAX
10 FPGA where illuminance I lux is derived using an empirical formula to approximate the
human-eye response.
shows the connection of APDS-9301 to the MAX 10 FPGA.

Humidity and Temperature Sensor
The MAX 10 Plus 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 Plus so that user can make ambient temperature measurement
without heat interference from the heat source of MAX 10 Plus.
