4.4.6 Light Sensor

A TEMT6000X01 light sensor is mounted on the AVR-IoT Wx board for measuring the light intensity. The sensor is a current source that will induce a voltage across the series resistor, which in turn can be measured by the ATmega4808 ADC. The current is exponentially relative to illuminance, from about 10 µA@20lx to 50 µA@100lx. The series resistor has a value of 10 kΩ.
