Excellent for prototyping, but not beyond.
For real world battery-powered usage this won't work well because it wastes a lot of power on the LED and the voltage regulator. I removed the LED (-4mAh), and will eventually just desolder the DHT and wire it directly to the ESP-01 (I don't need the regulator).
Significant self-heating (3-5⁰C, depending on input voltage), but otherwise works well.
