This is a DHT 21 (11/22) [I use AM2301] sensor powered by a ESP8266 (12-E). It is meant to be run off of 2 AA batteries, hence the reason for the U1V10F3 3.3v pull-up from Pololu. It includes deep-sleep circuit and the necessary reset/flash (burn) buttons. It also includes battery level detection…

It includes deep-sleep circuit and the necessary reset/flash (burn) buttons. It also includes battery level detection (though the resistor size likely needs to be adjusted.) Here is a component list:
R1= 1M
R2= 220k
R3= 10k
R4= 10k
R5= 10k
R6= 10k
R7= 10k
R8= 10k
R9= 470
C1= 0.1mF
The headers for the DHT 21 (11/22) are in the upper right corner.
This is an untested REV A board
Purpose: Interior low-power temperature/humidity sensor powered by 2-AA batteries.
This is my 1st EagleCAD/PCB project
