Like this Daniel. You can warm the DS18B20 to make it turn off the heater, or ditto for the DHT22 to turn heater on.

Check the wiring input to the mosfet from the arduino
S = signal from arudino pin 9 for CH1, etc
+/- = +5V, ground from arduino. If you have the Nano then its a simple connect for each channel
