LoRa SX1278 Ra-02 433M 10KM Predajnik rasirenog spektra

Opis:
Ra-02 je zasnovan na SKS1278 bežičnom prozirnom modulu za prenos (primopredajnik jedan), sa IPEKS utičnicom može da poveže spoljnu antenu.
Korišćenjem napredne tehnologije širenja spektra LoRa, udaljenost komunikacije je 10000 metara, super korekcija grešaka, sposobnost sprečavanja smetnji, sa funkcijom buđenja vazduha (ultra niska potrošnja energije). Može se koristiti u okruženju sa hiljadama ljudi, posebno za očitavanje brojila, pametnu kuću, protuprovalni alarm i drugu opremu.
