Chinyorwa: Chinyorwa chedata (chinonziwo datalogger kana data rekodhi) chinhu chemagetsi chinonyora data nekufamba kwenguva kana maererano nenzvimbo kungave nechigadzirwa chakavakirwa-mukati kana sensor kana kuburikidza nezviridzwa zvekunze uye sensors. Kuwedzera, asi kwete zvizere, ivo vakavakirwa pane dhijitari processor (kana komputa). Iwo anowanzo kuve madiki, anotyairwa nebhatiri, anotakurika, uye akashongedzerwa ne microprocessor, ndangariro yemukati yekuchengetedza data, uye sensors. Mamwe ma data logger anosangana nekombuta yemunhu, uye anoshandisa software kumisikidza iyo data logger uye kuona uye kuongorora iyo data yakaunganidzwa, nepo vamwe vane yemuno mudziyo interface (keypad, LCD) uye inogona kushandiswa seyakazvimiririra mudziyo. Mubvunzo: Ndeipi saizi ye data logger?
