Is it possible - foreseeable - that you might create a PiicoDev UV sensor using the VEML6070 chip?
Looks like a very close cousin to the existing VEML6030 used in the PiicoDev Ambient Light sensor …
Just a thought - especially for a weather station for measuring UV (sunburn) data. Could also be used in conjunction with the existing sensor (and some calculations) to determine solar energy in watts / sq. meter etc etc for the off grid people.
Thanks for the update - it’s a pity re the VELM6070 as it looked like a simple drop-in replacement …
Maybe they didn’t have enough interest in it for ongoing production … or maybe they have a later version?
Hey @Murray125532 - we actually had the same idea (for exactly the same part) a while ago. During my preliminary research, I came across this incredible project by experienced maker, mixtela that uses the device. While the project is gorgeous and beautifully designed, he’s still pretty unimpressed with the VEML6070. Mixtela points out numerous shortcomings, both at the hardware level and in the documentation. While these were enough to convince me to stay away from the VEML6070, I still recommend watching the video - some first-rate making there!
As Peter said, we’ll keep our eyes out for a suitable device. If you find one in your travels please let us know!
(a) wow that is a serious make there
(b) agree with your comments
(c) one of my Cub Leaders found some small plastic UV sensitive beads that we had the Cubs make up into additions to their scarf woggles. The beads were normally whitish, but when exposed to UV i.e. sunlight, started to turn purple. We suggested to the Cubs that if the purple was ‘vivid’ that maybe they should go into a shelter until the beads returned to white again. A simple Sun Safe idea for youths.
And there is this one from Adafruit … I was actually looking up the LTR390-UV-01 sensor, made by LiteOn optoelectronics - which Mouser can get in, but at a long lead time (20+ weeks) and big minimum order qty (5000) unfortunately …
