Product Description
| Description The LTR390 is one of the few low-cost UV sensors, and it's a pretty good one! It has both ambient light and UVA sensing capabilities, with a peak spectral response between 300 and 350 nm. You can use it to measure how much sunlight you can get before you need to cover up. Unlike the Si1145, this sensor will not give you a UV index reading. However, the Si1145 does a UV index approximation based on light levels rather than true UV sensing. In contrast, the LTR-390 does have a real light sensor in the UV spectrum. It also has a simpler I2C interface, so you can easily run it on an Arduino or Python microcontroller/microcomputer. Unlike the GUVA analog sensor, the bias and ADC are internal, so you don't need an ADC. Product size: 18*25.5MM Product weight: 3g |
