Grab Temp/RH from DHT11 and display on PiOLED 128x32
Raspberry Pi 3B+ - although use using generic Python with common libraries, so it should work on most Pis
DHT-11 Temperature/Humidity Sensor - Just had it laying around
PiOLED 128x32 lcs display - Also just laying around
Configured I2C on Pi for display

Setup and Usage of Pi OLED Wiring and Coding for DHT11/22
Follow instructions for Setup and Usage of Pi OLED and Wiring and Coding for DHT11/22
Run tempMain.py
I added the disp.image(image.rotate(180)) because the way the PiOLED connects to the GPIO Header. The power port on the Pi is opposite the GPIO Header, so I cannot set the Pi on edge so that the PiOLED is right-side up with power plugged in. #SoftwareToTheRescue
I refered to Run a Program On Your Raspberry Pi At Startup to decide how to make this program run at startup. I chose Method 4, systemd because I want this running always. And, I'm pretty comfortable with systemcrt process management
