Czujnik zalania

[adgl]

Prośba o informacje co teraz polecacie na czujnik zalania. Jak soft z GG ustawić ?

[Zibi]

Czujnik zalania dla wygody swobodnego rozmieszczenia i bezpieczeństwa powinien być zasilany z baterii. Wgrywając GG raczej tego nie uzyskasz szybko układ skończy swoją prace ze względu na pobór ESP.
W sieci są różne czujniki ale jakoś nie miałem przekonania.
Ja zrobiłem to od podstaw.
Nadajnik procek + układ radiowy hc12 wykrycie wody wysyła sygnał do odbiornika leci powiadomienie na tel. Co 5 dni czujnik wysyła raport o napięciu baterii na telegram, kiedy chce znać napięcie to odpytuje czujniki, jeśli bateria spadnie poniżej danego progu to czujnik sam wyślę powiadomienie na tel że czas wyjąć i naładować aku. Już ratował życie chodzi rok bez zastrzeżeń.

Kolego to już pełna kontrola , ale ja takiego sprzętu nie zbuduję i nie oprogramuję. Szukam prostszego rozwiązania, ale dziękuję za profesjonalną propozycję.

Witam ja mam 5 takich czujników https://allegro.pl/oferta/czujnik-zalan ... 8121110884
Połączonych z bramką Sonoff RF Bridge. Do tego powiadomienie połączone wszystko skryptami z zaworem odcinającym wodę.

A dlaczego nie kupisz czujnika tuya z pierwszych stron tego wątku i nie grasz biharki elmaya też z początku tego wątku?
Tutaj dalej wszystko działa jak działało.

Hi @elmaya,

do you remember which GPIO is connected to the Reed switch/water sensor in that devices from first pages? I bought one, I can easily flash it and wanted to write my own soft for this to use it as trigger for water pump.
To wake it up on reed switch toggled, read status and send data to Supla, then go to sleep.

Hi @elmaya,

To wake it up on reed switch toggled, read status and send data to Supla, then go to sleep.

The sensor is not connected to ESP8266, it is connected to STC8F1K08S2 MCU.
This auxiliary MCU communicates with ESP8266 through TX-RX and controls the power supply of the ESP8266.
I attach the source code of my project so you can analyze how it works.
good luck.

Jedyne co możesz zrobić to go wymienić na ESP ale nie wiem czy będzie to działało. Ja robiłem to w zaworze do wody i śmiga ale tutaj nie wiem. Z drugiej strony jak nie spróbujesz to się nie dowiesz.
Powodzenia
