VEML6070 UV sensor sensitivity test (Wemos D1 mini Pro, ESP8266, Arduino IDE)
In this video I'd like to present you VEML6070 UVA light sensor. I originally wanted to use the sensor to build a sunglass UV filter tester but the measurement of it's efficiency is approximate-based on the sensitivity characteristic of the sensor-it also responds to the visible light (see the sensor datasheet here: http://www.vishay.com/docs/84277/veml... )
0:00 Basic characteristics of the sensor
0:07 Setup and wiring
1:15 Code upload (see https://gist.github.com/xxlukas42/757...)
1:26 Basic test
1:39 Performance characteristics
1:45 Test of UV filter of sunglasses
