Battery Life Extender
I wqas trying to use a NodeMCU for a remote temperature monitor. The ssleep mode still uses was to much current for a battery powered device. This circuit should enable me to run for months on to AA or AAA batteries. The NodeMCU is programmed to supply a DONE signal after it transmits the Temperature and Humidity A small switch is provided to allow the user to trigger the timer so they don't have to wait the 30 minutes.
