Hello dear friend,

Right now I'm testing a DTH22 sensor with a Pro2 TX board v3.12 and latest TX software (7.0_b003) without any change and it is working as expected.

Here is some of the DHT22 readings I get on the serial monitor:

Code:

Sending ID0...
  ensor 0 - Temp: 0.00  Hum: 0.00
  Sensor 1 - Temp: 13.90  Hum: 79.40

Sending ID0...
  ensor 0 - Temp: 0.00  Hum: 0.00
  Sensor 1 - Temp: 14.00  Hum: 79.20

  ensor 0 - Temp: 0.00  Hum: 0.00
  Sensor 1 - Temp: 14.10  Hum: 79.00

  ensor 0 - Temp: 0.00  Hum: 0.00
  Sensor 1 - Temp: 14.30  Hum: 78.70

Sending ID0...
  ensor 0 - Temp: 0.00  Hum: 0.00
  Sensor 1 - Temp: 14.40  Hum: 78.40

Sending ID0...
  ensor 0 - Temp: 0.00  Hum: 0.00
  Sensor 1 - Temp: 14.50  Hum: 78.30

There is one thing I noticed from your pictures: The DHT22 pin3 should be left unconnected (the one you have connected to CLK).
Try disconnect the pin 3, then it should work.

Waiting to hear from you.

My best wishes of an Happy New Year.
