Product description
Ltr390 Is One of the Few Low-Cost UV Sensors, and It Is Very Good! with Ambient Light and UVA Sensing Function, the Peak Spectral Response Is between 300 and 350 Nanometers. You Can Use It to Measure How Much Sunlight You Can Get before You Need to Cover It.
Unlike Si1145, This Sensor Does Not Provide You with UV Index Readings. However, Si1145 Approximates the Ultraviolet Index According to the Light Level, Rather than the Real Ultraviolet Induction. In Contrast, LTR-390 Does Have Real Ultraviolet Spectroscopy in Optical Sensor. It Also Has a Simpler I2C Interface, So You Can Easily Run It on an Arduino Or Python Microcontroller/Microcomputer. Unlike Guva Analog Sensors, Both Bias and ADC Are Internal, So You Do Not Need ADC.
In Order to Use It as Easily as Possible, We Put Ltr390 on Stemma QT-Shaped Split PCB with a Small Number of Supporting Circuits to Provide You with Choices during Testing. You Can Use Bread Board Or SparkFun Qwiic Compatible Stemma QT Connectors and Are Compatible with the Common 5V Voltage Level on Arduinos, as Well as Many Other Boards (Such as Raspberry Pi Or Our Feathers) 3.3V Logic Used. Qt Cable Is Not Included, but We Provide All Kinds of Fast Plug-and-Play Support in the Store.
