RPI is not good handling DHT11

Hello?

This is failure story about converting c code to python.

There is GPIO controlling library on Python such as RPI, wiringPI.

But they are not enough to controlling high frequency data.

some people already investigate about it.

Follow code return wrong values because frequency.

So I should hybrid c++ and python codes.

Change whole things.

Hello?


I decide to renew whole devices.




Finally, there is a lego frame for raspberry pi.

This one has motion sensor, humid sensor, camera, IR receiver.

I will use Django, python for gathering daily logs.

Fun coding guys :)
