The Vishay Optoelectronics VEML6030 includes an ambient light sensing photodiode and all the signal processing circuitry required for it to be read by a microcontroller via I²C interface on a single chip. The sensor has 16-bit resolution which can deliver up to 0.0036 lux per count. It features Vishay’s patented Filtron on-chip coating for maximum performance and allows the user to program upper and lower thresholds to avoid constant polling by a microcontroller.
