Non-functioning sensors

[50915091Mica]

Hi there,
unfortunately I have to ask you for help once more. Without much of a changes in raspberry running TerrariumPI I started to experience problems with sensor reading. Firstly wihout problems, than one DHT11 sensor started to show unrational numbers and I deleted it from the sensor list. Now, after one of reboots none of thw two remaining DHT 22 sensors give any readings. after screen -r command it prints :

kkk'! Got invalid value 66.900002% in 5.57930 seconds

There are now two DHT22 sensors (strangely named I admit), both with 4,7 resistor, connection cables intact.
The values vary - I don´t think that the value near 70% must be wrong and doesnt seem to me as "invalid"
The values above 3000 - well I read it could be caused by voltage - sensors are connecter to 3,3V and some say that 5V makes it dissappear, what do you think?

Thanks for your reply

Some errors I have to fix some code. But the warnings are correct in such a way, that the measured values are outside the given min and max value. This is done to overcome some wrong readings. So the amount of 3314.800049% is invalid due to big. But a value lower of 100 is valid if the sensor has a max of 100.

So, could you check if you have correctly setup your sensors? By default any humidity value between 0 and 100 should be valid.

Also this is for me the reason not to use GPIO but I2C or OWFS. That is in my opinion more stable
