The voltage supervisor finally solved my problem. It´s working for 1 week without failure. The ESP doesn´t get to "limbo state" anymore and does it´s job. Thank you verry much for the tip again

I´m wondering how you implemented, that the ESP32 goes to Deep Sleep before the brownout occures. There must be a detection that recognizes when my ESP is close to brownout or how did you do that?

thank you, I will try that out. I´m currently waiting for my voltage supervisor.

Hello, i don´t think i can provide a detailed hardware picture, because it´s part of the concern i´m working in. Basically: I got my Solar modul. On my board theres a buck converter which bring´s the voltage to 3.3 V (the solar cell brings around 35V normally). The solar modul is my only power suppl...

thank you verry much everyone, i appreciate it.

chegewara that voltage supervisor looks promising and could be the reason for my problem. Especially because i use solar energy as a power supply. I will try that out, thank you verry much!

Hello Craige,

in my case the ramp up from 0-5V can be pretty slow. Is there a way how i can tell the ESP32 that it should only start when the voltage is like 10V or something. I could create a switch case in my Software, but therefore the program must start which isn´t always the case.

Hello everybody. As i wrote in another topic, i have a problem, that my ESP32 doesn´t restart properly sometimes. When i do esp.restart() it doesn´t help, but when i take away the current for a short time, the ESP32 starts again. So i want to implement something like that in my Software ("Hard Resta...

Hello everybody, i have a problem with my ESP32 that annoys me for a long time and i can´t figure out what the problem is. My Esp32 takes messurements, which works fine. When there is not enough voltage or current, the ESP32 shuts down (which is good) and only reboots when there is enough Power (tha...
