I have got a cell phone charger and it is 5v 2a (it says).It's what I use to power my raspberry pi. But there is still a lightning bolt icon on the top right of my screen. It barely goes off. Should I be scared ?
Hey everyone ! I will build a project which I must detect fire if there are fire first. So which gases are releasing commonly in every fire . And which sensor /sensors should I use to detect fire. English is not my main language,I apologise for my bad English.
