Display. I used old case from iPod. Sprayed a little red paint and top it with black. Push button at the bottom of the case.

I am using RCWL-0516 Microwave Radar Sensor for on/off the display. This sensor is very sensitive. I just want to activate the display in a close range. Any suggestions?

Can you add additional code; Close the cover if Fan does not start and display error that fan has no power. Thank you.

Finish! Thank you for all your help!


In the beginning, I connected the DHT sensor to Pro Mini A0 and separate power supply (5V) and ran DHT Example sketch and eading was "nan". Want to mention that all other wires (FAN setup ) attached to Pro Mini as well. Then I disconnect Pro Mini from setup and connect DHT to it (GND, VCC, and A0) got numbers by running DHT Example. Connect everything together (motor, display, radio) and connect DHT to Pro Mini (GND, VCC, and A0) turn on and got zeros for Temp and Hum. Got frustrated and left for a walk. When I come back, Temp: 85 and Hum 52. I was not patient enough. It takes 5 to 6 min for Temp to show on display. I also tried to connect DHT VCC to the external power supply 3.3 and 5 V, but leave GND connected to Pro Mini and it works.

Thank you, guys.
Got the DHT working! Next step connect motor and fan, fingers crossed

I am using 5V power supply and testing sensor with DHT example. DHT is working with MEGA power by 3.3 or 5 v. Maybe it is not working because of Pro Mini 8MHz?

Replaced NRF24L01+ and it is working now.
Having trouble with DHT22 it is working on MEGA, but not on Pro Mini ATMega328P 3.3V 8MHz any suggestions

.......Thanks

Thank you very much. Star Over. Rewire display and change the code. Never thought I would be excited to see the word ”Error” on display :).
I got five NRF24L01+. Two of them are not working at all. Looks like the one on the gateway working ok, but the node is unstable.
Do I need to create an additional device for Fan in Vera or, it will be displayed within the MySensors serial gateway?
