With ambient light and UVA sensor with a peak spectral response between 300 and 350 nm. You can use it to measure how much sun you can get before you have to cover up. Unlike the Si1145, this sensor does not give UV index measurements. However, the Si1145 performs UV index approximations based on a light level, not real UV sensor. The LTR-390, on the other hand, has a real light sensor in the UV spectrum. It also has a much simpler I2C interface so you can easily run it on the Arduino or Python microcontrollers\/microcomputers. Unlike the analog GUVA sensor, the bias voltage and ADC are all internal, so you don't need an ADC. To make it as easy to use as possible, Adafruit has built LTR390 on a breakout PCB in the Stemma QT form factor with a sprinkling of support circuitry to give you options when testing. You can use either a breadboard or the SparkFun Qwiic compatible STEMMA QT connectors and compatibility with 5V voltage levels commonly found on Arduinos, as well as 3.3V logic used by many other boards such as the Raspberry Pi or the Springs is used. QT cable is not included.\u003c\/p\u003e \u003ch3\u003eProduct Features\u003c\/h3\u003e \u003cul class=\"a\"\u003e \u003cli\u003eCheap UV sensor\u003c\/li\u003e \u003cli\u003eDetects both ambient and UVA light\u003c\/li\u003e \u003cli\u003eEasy to use with STEMMA QT and Qwiic connectors.\u003c\/li\u003e \u003cli\u003eWorks with 3.3V and 5V logic\u003c\/li\u003e \u003cli\u003eHigh quality product\u003c\/li\u003e \u003c\/ul\u003e","published_at":"2024-03-12T18:40:40+11:00","created_at":"2024-03-12T18:40:44+11:00","vendor":"Adafruit Industries","type":"Photoelectric sensors","tags":["industryDE"],"price":15400,"price_min":15400,"price_max":15400,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":45409625637101,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"de-B0929NRNT3","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Adafruit Industries LTR390 UV Light Sensor - STEMMA QT\/Qwiic","public_title":null,"options":["Default Title"],"price":15400,"weight":700,"compare_at_price":null,"inventory_management":"shopify","barcode":null,"requires_selling_plan":false,"selling_plan_allocations":[]}],"images":["\/\/leoforward.com\/cdn\/shop\/products\/51DRIPqaZ6L.jpg?v=1710229244","\/\/leoforward.com\/cdn\/shop\/products\/51k-mRWSm_L.jpg?v=1710229244","\/\/leoforward.com\/cdn\/shop\/products\/410iIyeCOuL.jpg?v=1710229244"],"featured_image":"\/\/leoforward.com\/cdn\/shop\/products\/51DRIPqaZ6L.jpg?v=1710229244","options":["Title"],"media":[{"alt":" [AUSTRALIA] - Adafruit Industries LTR390 UV Light Sensor - STEMMA QT\/Qwiic","id":32619040211181,"position":1,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/leoforward.com\/cdn\/shop\/products\/51DRIPqaZ6L.jpg?v=1710229244"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/products\/51DRIPqaZ6L.jpg?v=1710229244","width":500},{"alt":" [AUSTRALIA] - Adafruit Industries LTR390 UV Light Sensor - STEMMA QT\/Qwiic","id":32619040243949,"position":2,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/leoforward.com\/cdn\/shop\/products\/51k-mRWSm_L.jpg?v=1710229244"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/products\/51k-mRWSm_L.jpg?v=1710229244","width":500},{"alt":" [AUSTRALIA] - Adafruit Industries LTR390 UV Light Sensor - STEMMA QT\/Qwiic","id":32619040276717,"position":3,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/leoforward.com\/cdn\/shop\/products\/410iIyeCOuL.jpg?v=1710229244"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/products\/410iIyeCOuL.jpg?v=1710229244","width":500}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eAdafruit Industries LTR390 UV Light Sensor - STEMMA QT\/Qwiic\u003c\/h3\u003e \u003cp id=\"b\"\u003eThe LTR390 is one of the few inexpensive UV sensors available, and it's a pretty nice one!
