    Hi Sanjoy, the ESP12E cannot be easily programmed stand alone. So either you connect it to another board to program it, or you program it when soldered to the atmoscan board. Specifically, the atmoscan board inclides a programming circuitry that is in line with the NodeMCU. To program it you should connect a USB-Serial adapter (e.g. FTDI232 or similar) to the J7 connector (next to the reset button). Program can be uploaded without sensors connected, except that you should ground the interrupt line of the geiger sensor, Pin3 in in the RAD connector, otherwise the board will not boot. If nothing is connected to the board i am not sure if it will boot. Some sensors initialisation is blocking, courtesy of the provider of the library. One example is the multigas library. However, you could d...

    Hi Sanjoy, the ESP12E cannot be easily programmed stand alone. So either you connect it to another board to program it, or you program it when soldered to the atmoscan board.

If nothing is connected to the board i am not sure if it will boot. Some sensors initialisation is blocking, courtesy of the provider of the library. One example is the multigas library. However, you could disable the related process, see the Q&A section. When it boots, it should recognise that it is not configured and should open a wifi hotspot, to which you can connect and set it up. Among the settings, there is a syslog server that helps greatly debugging. You can increase the logging level by uncommenting the #define DEBUG_SYSLOG in the GlobalDefinitions.h file.Serial is used only for first programming. After that, OTA programming via wifi is the preferred option.Please let me know if you succeed.

    Hi, i checked and in fact regular postage is cheap. Not sure if reliable though. I have the last PCB available and I would love to get it to the other side of the planet! Let me know if interested via private message.

    Check on Postnl.nl (20-50 grams letter) and send me a private message!

    please send a private message via instructables if you are interested... I am losing track of who is who already!

    hi there, greetings from Europe. See the new Q&A section!

    I thought i had replied but i dont see it... Thanks!

    Forgot: I really wanted to add sensors for H2S but only could find analog ones and never had the time to design a I2C A/D board. Methane and ammonia should be sensed by the MiCS6814 board but frankly i believe its design is flawed so i only use it for NO2. There is room for improvement and if anyone wants to work on it i'll be happy to contribute ideas

    hi, see the new Q&A section!

    Thanks foryour interest in my project! I answe the same way... Plenty of people asked for a PCB, way more than I everthought… I had the PCBs made by dirtypcbs.com and my files worked out justfine. Good quality and cheap enough, 25USD / 20Euro for 10 PCBs. I used two andhave 8 available so I would ask 2 Euro + shipment (depending on location andshipping preferences) just to recover the bare cost. I am afraid I will have topick the first ones that send me a private message and you will have to waitfor the weekend to have it shipped… busy week!
