I have been thinking that I would like to add a external light intensity sensor to one of my ruuvitag. I’m using now default firmware and ruuvicollector so I need to modify those but my question is, why kind of sensor i can connect? Would this work https://www.addicore.com/BH1750FVI-p/ad290.htm ? Can I still use internal sensors if i add the intensity sensor?
You can solder the sensor to the test points on the bottom of RuuviTag with some wire. You can keep on using the sensors onboard RuuviTag, but you’ll have to code the support for your sensor
