Micropython ESP32 temp sensor based on DHT22 sensor
This script requires the ssd1306 and umqtt.simple libraries to be frozen in the Micropython build or you will run out of memory. I renamed the simple.py script because it needed to be in the modules directory to compile.
Modify the wifi_cred_example.py to your settings and transfer it to the esp32 also. If your broker doesn't require a user/pswd, just remove the relevant lines from the script.
