Thanks,
I just hooked up the sensor to an ESP-07S, which I just received, and used the Arduino DHTtester sketch to verify that it is working. With the sensor in the breadboard and the Rpu=10K it works OK.
But the test sketch is a bit strange because it sends a start signal that is 20 ms in length and this is the maximum allowed by the data sheet...
I will see where it is defined and change to a shorter value.
So far no long cable attached at all...
Next on my agenda is to do the following:
- Add WiFi capabilities to the sketch (connect to my home network).
- Add some kind of timer that only makes a reading every hour or so.
- Find a way for the module to post the data to a my webserver where it can be saved with a timestamp.
I have seen some examples of posting data to servers but they were always someone else's server and there had to be an account etc. I want the data to be sent to my own webserver in a form that can be retrieved by a php script...
