xman12 Mein Gerät hat kein CE Zeichen, wofür auch? Selbst wenn eines aufgedruckt ist hat das keinerlei Bedeutung. Jeder kann das CE Zeichen aufkleben aber versuchen sie mal den chinesischen Hersteller dafür zu belangen wenn das Gerät doch nicht CE-Conform ist.

xman12 I don't know what you asking for. First, I have the radiation counter not there, it should last more than 2 weeks till it is there. Second, if you mean the GeigerMüller tube, look at the description of the radiation counter, there is listed which GM-Tube is used.

xman12 I can't answer this because I do not get the device until now. I have to wait another week, I fear. Non posso rispondere perché non ho ricevuto il dispositivo fino ad ora. Devo aspettare un'altra settimana, temo. Sorry this is translated with google-translator :-)

xman12 I want to use this thing for an weathersensor later and I do not use it till now. Its is possible that you have to flash the Firmware first to use this product. For arduino you have to flash the ESP8266 NonOS SDK or ESP8266_RTOS_SDK.I bought many ESP01S moduls at amazon in the past and many of them were not flashed and not usable in the delivering state. After I flashed the ESP8266 NonOS SDK Firmware all of them are working. I have no experience with the ESP8266_RTOS_SDK, not tested it yet.

xman12 You should Ask this the Seller , not me. My Bltouch do work but not flawless. Sometimes the needle comes out and do not go inside the Bl-Touch again. After that the needle touch the Bed all the time and when the Extruder goes to the left side the needle goes down next to the left side of the bed. If the extruder then move to the right direction the needle will bend aside because it colide with the left side of the Bed. this happens sometimes after the bed was messured after more 4 or 6 times, sometimes this happens after it mesured the last testpoint upper right of the glasbet. Also there ist in bug in the Printer Firmware, if you manualy move the z axis into the menue (not z axis offset! but the Move menue) to move the extruder up a bit and then start the measure procedure it will measure correct but then collide with the glasbet and destroy the surface. I have not reconized the exact procedure to make this bug happen. It seems that the Printer do not correct set the Value of the Move Menue back to standard, or something else. I Have the Board 4.2.2 inside with the silent steppers.

xman12 Should be the 0,4mm nozzle.

xman12 BMP180 search "Github BMP180.h" BH1750FVI search "Github Update BH1750FVI_Simple.ino " There are many code samples on github, I am not good in coding. May be someone other has better code samples.
