I've got this sensor, for the past two weeks i'm trying to connect it to irrigation board V10.4. I literally tried every single pin as well as the settings. Im using 10 ohms resistor connected between 5V and data. I can't get any reading from the sensor. What might be the issue? Which pin should i connect it to on the V10.4 irrigation board? Grazie/Thanks for help :)

Hi there,
some comments:
- there was a problem in the release 3.24/3.25 using this sensor. The problem was due to a missing python package in the new Raspbian release which in the previous releases was installed by default. It is now fixed in rel 3.26.
- the sensor in the link looks like the DTH22 (not the AMD2302 which has an additional resistors and a couple of capacitors) so they have to be added manually as you did.
- If you plan to have only one sensor for air humidity and temperature, better to use the BME280, it uses the I2C interface and it is more accurate (at about the same cost).
