TMT6000



  • @stress-nero said in TEMT6000:

    Hello first time user here, I have been trying to build a 4in1 light, motion, tem/hum using a nano, temt6000, dht22, and sr501 using the examples and already made sketches i can combine everything, but i am not sure if i am entering the info for the temt6000 correctly. Can someone take a look please```

    sorry for the double post.


  • Mod

    @stress-nero what is the purpose of the double post? Which one should I delete?



  • @mfalkvidd the one in development when i posted i did not realize that it was under development, and can you help me sorting the tmt6000 sersor out for the sketch.


  • Mod

    @stress-nero sorry I don't even know what a tmt6000 is.



  • @mfalkvidd it's a ambient light sensor. I was going to use a esp8266 with these to make a 5in1 node inspired by a video i saw with just header wires , but decided to use arduino nano instead. What i posted seems to work ok but being brand new i figure i would let someone else take a look and see if everything was ok with what i have so far or if i could make it better.

  • @stress-nero the light values was fixed bad jump wire position,
