Abstract

Inventia se refera la o instalatie automata, care sa protejeze suprafetele agricole cultivate cu legume si fructe de efectele negative ale brumei. Instalatia, conform inventiei, în scopul protectiei contra brumei include rezistente incendiare care pentru aprinderea materialelor fumigene sînt introduse în circuitul electric al bateriei prin anclansarea a doua relee aflate în colectorul unui transzistor care intra în stare de conductie, în momentul în care temperatura scazînd sub 1 degree C, coloana de mercur a unui termometru coboara deschizîndu-se astfel cele doua fante orizontala si verticala, iar lumina unui bec cade pe o fotodioda aflata în baza unui tranzistor care în acest moment începe sa conduca.
