Drugi koniec rury jest otwarty. Na samym dole rury wywierciłem otwory na około rury i rura do samego dna.

Mam pytanko, na schemacie napisane jest rezystor 180K, a na rysunku w kodzie kolorów jest to 150K, to ile właściwie powinno być?

Czy mógłbyś podzielić się "patentem", jakiego typu i średnicy rury użyłeś, oraz jak ją dokładnie połączyłeś z króćcem czujnika?mirizag wrote: Sun Jun 02, 2019 10:05 am Drugi koniec rury jest otwarty. Na samym dole rury wywierciłem otwory na około rury i rura do samego dna.
Z góry dzięki.

Zmontowałem sobie układ do pomiaru ilości wody w studni (9,5m) czujnik MPX5100 oraz przekaźnika do załączania pompy podlewającej ogródek. Od układu do dna studni poprowadziłem 15m wężyka 4mm. Przekaźnik sterowany jest przyciskiem fizycznym oraz za pomocą supli. Do źródła kolegi elmaya dołożyłem jeszcze BMC280 mierzący temperaturę i ciśnienie bezwzględne. Wszystko "niby" działa ale nie do końca. Pomiar ilości wody dla compensation 750 zaniżony był o ok 1m skorygowałem go ustawiając na 340. Przekaźnik również niby działa ale na jego stan w supli wpływa zmiana poziomu wody. Czy ma ktoś jakieś pomysły?
