raspberrypi-mqtt-light-sensor's Issues

Add configuration file

A configuration file is necessary to change to GPIO pins and timeouts without editing code.

Change run condition

while len(times) < __SAMPLES or delta_t.total_seconds() < __MIN_TIME_SECONDS:
This should be changed because it forces the loop to run until all measurements have been taken and the time passed.
In low light conditions this leads to the problem that it takes very long to publish a new Matt message because the capacity can take up to a minute to charge which adds up quite fast.
The primary criteria for the loop above should be time. In bright situations the capacity is charged very fast this leads to the situation where the limit is throttling as intend. In low light situation we could skip the value rounding and always pass the measured value.
A solution would be to set __samples to 1.
Only drawback would be that we loose a bit of precision in low light because no average would be taken.

Setup descripition for pypy

Pypy description needs to added to describe the project better.
