Zitat Datenblatt: "Programmable Interrupt Function with
User-Defined Upper and Lower Threshold
Settings"
Anderes Zitat: "The TSL256x devices also support an interrupt feature that simplifies and improves system efficiency by
eliminating the need to poll a sensor for a light intensity value. The primary purpose of the interrupt function is
to detect a meaningful change in light intensity. The concept of a meaningful change can be defined by the user
both in terms of light intensity and time, or persistence, of that change in intensity. The TSL256x devices have
the ability to define a threshold above and below the current light level. An interrupt is generated when the value
of a conversion exceeds either of these limits."
