Env vs Hat Env
-
Hey all,
finally i have some time to play with Env Hat, at first time there was some strange readings +-5% diff then normal env.
Now there was time to check this out and here it is:
and HW inside:
HW info:
M5StickC ENV Hat (DHT12, BMP280, BMM150)
ENV Unit with Temperature Humidity Pressure Sensor (DHT12+BMP280)Inside ENV Hat we have DHT12 without blue case du the size, but why there is so big difference between normal Env ?
Any clue ?
Just BTW i have 3 Env Hat and all works in same way.
Regards

If you have the OLED and WiFi on, the heat they produce will skew the results. I connect the ENV hat to my Stick C with wires, and I get different, lower-temp results.

Ok let me try it. So the whole clue of env hat should come with some kind of shield to eliminate heat from stick.

So after test with extra cables all is ok when hat is moved out from stick.
But this is a main clue of hat to stick it in to StickC without extra lobg cable.
@lukasmaximus please comment this, for me this looks like design issue.

Can you tell me how to compile the code I am confused on how to bring the code into the Arduino IDE.
I created a main sketch and then copied the code into Mstickc_ENVHat, I also created 4 tabs.. DHT12.cpp, DHT12.h, and bmm150.cpp, and bmm150.h, and bmm150_defs.h...
I get errors
C:\Users\AppData\Local\Temp\arduino_build_90317\sketch\MstickC_ENVhat.ino.cpp.o:(.literal._Z4loopv+0x34): undefined reference to `DHT12::readTemperature(unsigned char)'

@grlind well its simple UIFlow drag and drop showcase.
I will try to do same in arduino today. -
@mati I have mentioned this to Jimmi, and his answer basically was, well don't use wifi and OLED. Not exactly a practical answer. I'd rather have a long hat, isolating the DHT and BMP from the heat.

rlly ?! hmm what's the point of making HAT with req extra cable to unHAT it :D
ok let's end this topic as a lesson. thx @dda for info. -
@grlind I was able to get to work in Ardunio I just combine the DHT into the main sketch all things good though the pressure reading are off... I owuld like to see the uflow - I have not done anything in uflow want to try it.. Is your code posted somewhere?
