I've used two GPIO pins - one to power up the DHT22 and the other to read it. This has now been running off an 18650 Li-ION battery for 24 hours and wakeup/deep sleep cycles of 10 minutes. All seems to be good so far.
Hi, I'm working on the same topic here in Switzerland. ESP201 with DHT22 and 18650 Battery. Currently I'm using a NodeMCU board for the SW development. I send the data using TCP with static IP to a node-red installation on a RasPi. I got UDP working too, wich is even faster and saves on battery energy. Would you be so kind to post the wiring of your module?
Thanks,
Urs.
BTW: node-red with TCP input works nicely, the UDP input is not working yet. aarrgh
