Инструменты разработки оптического датчика PmodALS - Ambient Light Sensor
The 410-286 is an Add-on-Board for PmodALS, the PmodALS demonstrates light-to-digital sensing through a single ambient light sensor. The PmodALS utilizes a single ambient light sensor (ALS) for user input. The amount of light the ALS is exposed to determines the voltage level passed into the ADC, which converts it to 8-bits of data. A value of 0 indicates a low light level and a value of 255 indicates a high light level. The ADC081S021 is placed in normal mode by bringing the CS pin low and will deliver a single reading in sixteen SCLK clock cycles.
