Water alarm with ESP01, deep sleep and message via mqtt
Posted: 02 Apr 2021, 20:50
Hi,
I would like to build a water alarm sensor with the ESP01 (battery 3AAA).
I modified the ESP01 so that it goes into deep sleep. When water should be detected
the ESP01 wake up and report. The ESP01 should wake up at regular intervals
and send its status including the battery voltage via mqtt.
In order for the ESP01 to boot, the reset pin must be briefly set to high.
What's the best way to do this? With a transistor?
Greetings Dondolo
