Description

The LTR390 is one of the few low-cost UV sensors available, and it's a pretty nice one. With both ambient light and UVA sensing with a peak spectral response between 300 and 350nm. You can use it for measuring how much sun you can get before needing to covering up.

The LTR-390UV-01 is an integrated low voltage 12C ambient light sensor (ALS) and ultraviolet light sensor (UVS). This sensor converts light intensity to a digital output signal capable of direct 12C interface. It provides a linear ALS response over a wide dynamic range, and is well suited to applications under high ambient brightness. The sensor has a programmable interrupt with hysteresis to response to events and that removes the need to poll the sensor for a reading which improves system efficiency. This CMOS design and factory-set one time trimming capability ensure minimal sensor-to-sensor variations for ease of manufacturability to the end customers.
