Wiem, że sezon grzewczy się kończy, ale kilka dni temu kolega z forumowiczów @banan0100 poprosił o ten program to pomyślałem, że może jeszcze się komuś przyda.
Na wstępie dziękuję koledze @Elmaya za program viewtopic.php?f=9&t=4695 którym się posiłkowałem, oraz koledze @milion81 za ikonkę pieca z zasobnikiem.
Jest to czujnik odległości HC-SR04 wykorzystany do pomiaru poziomu opału w podajniku pieca. Montujemy go pod pokrywą podajnika.
Config programu oczywiście z możliwością aktualizacji online.
W polu update path wpisujemy również „/” czyli np. „/supla” dzięki czemu podając nr IP modułu:81/supla wchodzimy na stronę config online.
Jest to czujnik odległości HC-SR04 wykorzystany do pomiaru poziomu opału w podajniku pieca. Montujemy go pod pokrywą podajnika.
W configu oprócz danych serwera podajemy jeszcze głębokość zasobnika, żeby w aplikacji widniał faktyczny stan opału , a nie odległość od pokrywy podajnika do opału (Box depth in cm).
Czujnik odległości podłączamy pod:
GPIO 12 (D6) Trig
GPIO 13 (D7) Echo
Dodatkowo dołożyłem buzzer na GPIO 14 (D5) sterowany masą, który przy poziomie opału =< 20cm zaczyna wydawać swój przyjemny dla ucha dźwięk , oraz czujnik temperatury DS18B20 na GPIO 4 (D2)
W tryb config wchodzimy zwierając GPIO 0 (D3) do masy na 5s.
Po otwarciu pokrywy zasobnika, żeby odległość nie pokazywała się z minusem (zawiesza się Apka) zawsze pokazuje stan 2cm.
To chyba na tyle.
