I chose the DHT11 / DHT22 sensor because it reads a couple values and uses digital logic. The small ESP-01 module only has two digital pins free (GPIO0 and GPIO2). No analog pin is available so using a TMP36 sensor is out.
So what other digital sensors would also work:
Changing up the Internet interface and sending readings to Adafruit.io would be great also. It is all up to you.
