ESP8266 with Dual DHT Sensors over Cat6 Cable

2017-04-12-171642_1366x768_scrotI had read a lot discussions about how far a DHT11/22 Sensor could be from source and still get readings.  I decided to test two out from the screen porch to the deck.  Results above and on thingspeak channel.

I had to adjust/calibrate the sensors in the code because they were about 4 degrees off.  I’ll try the DHT reset procedure when I tear this project down.   Right now I’m happy to report that transmission is fine over > 20 ft of Cat6 cable.  Same readings as if it were plugged into the breadboard.
