Hello good morning, for some time I can not operate the sensors DHT22 and SHT21, the problem is presented with the PIC 16F887 and 18F4550, I can not take readings with the software component, with checksum and without checksum there are no readings of anything , already assemble the hardware properly and it does not work, also simulate with proteus and there are no readings, investigating in the forums still do not give solution to this problem for the PIC, the examples that you have of this component do not work, when you take them to the hardware there are no readings of anything. I made a replacement of the DHT22 for an SHT21 and with this are erroneous readings. with the software simulator it works very well, in proteus and hardware they are erroneous readings.
