光感測

The JSA-1130 is a high performance, high resolution, wide range ambient light sensor with stable measurement output and SMBus compatible I2C Interface. For ambient light conversion, a built-in ADC converts the ambient light in 100ms per sample and rejects 50Hz/60Hz flicker noise caused by artificial light sources. The JSA-1130 uses both a hardware pin and a software bit to indicate an interrupt event has occurred. An ambient light triggered interrupt is defined as a measurement which is outside a set window. The user may require that ambient light interrupt occurs at once, up to 16 times in a row before activating the interrupt pin. The low power JSA-1130 is designed for minimal microcontroller utilization, and to operate from 2.3V to 3.6V over the -40°C to +85°C ambient temperature range.
