Predstavenie sn\u00edma\u010da MQ-5:
\nMateri\u00e1l citliv\u00fd na plyn pou\u017eit\u00fd v plynovom senzore MQ-5 je oxid c\u00edni\u010dit\u00fd (SnO2), ktor\u00fd m\u00e1 ni\u017e\u0161iu vodivos\u0165 v \u010distom vzduchu. Ke\u010f je hor\u013eav\u00fd plyn pr\u00edtomn\u00fd v prostred\u00ed, kde je umiestnen\u00fd senzor, vodivos\u0165 senzora sa zvy\u0161uje so zvy\u0161uj\u00facou sa koncentr\u00e1ciou hor\u013eav\u00e9ho plynu vo vzduchu. Na prevod zmeny vodivosti na v\u00fdstupn\u00fd sign\u00e1l zodpovedaj\u00faci koncentr\u00e1cii plynu mo\u017eno pou\u017ei\u0165 jednoduch\u00fd obvod. Plynov\u00fd senzor MQ-5 m\u00e1 vysok\u00fa citlivos\u0165 na but\u00e1n, prop\u00e1n a met\u00e1n a dok\u00e1\u017ee sa lep\u0161ie postara\u0165 o met\u00e1n a prop\u00e1n. Tento senzor dok\u00e1\u017ee detekova\u0165 r\u00f4zne hor\u013eav\u00e9 plyny, najm\u00e4 zemn\u00fd plyn, a je to lacn\u00fd senzor vhodn\u00fd pre r\u00f4zne aplik\u00e1cie.<\/p>\n

Vhodn\u00e9 pre dom\u00e1ce alebo priemyseln\u00e9 monitorovacie zariadenia pre skvapalnen\u00fd plyn, zemn\u00fd plyn a plyn. Vynikaj\u00faca odolnos\u0165 vo\u010di etanolu a dymu.
\nVlastnosti modulu:
\n1, s pou\u017eit\u00edm vysokokvalitn\u00e9ho dvojpanelov\u00e9ho dizajnu, s pokynmi na nap\u00e1janie a pokynmi na v\u00fdstup sign\u00e1lu TTL;
\n2, s v\u00fdstupom sign\u00e1lu DO sp\u00edna\u010da (TTL) a v\u00fdstupom anal\u00f3gov\u00e9ho sign\u00e1lu AO;
\n3, TTL v\u00fdstupn\u00fd platn\u00fd sign\u00e1l je n\u00edzky. (Ke\u010f je v\u00fdstup n\u00edzky, sign\u00e1lka svieti, mo\u017eno ho priamo pripoji\u0165 k MCU alebo rel\u00e9ov\u00e9mu modulu)
\n4, anal\u00f3gov\u00e9 v\u00fdstupn\u00e9 nap\u00e4tie, \u010d\u00edm vy\u0161\u0161ia je koncentr\u00e1cia, t\u00fdm vy\u0161\u0161ie je nap\u00e4tie.
\n5, maj\u00fa dobr\u00fa citlivos\u0165 na plyn, detekciu zemn\u00e9ho plynu.
\n6, s\u00fa tu \u0161tyri otvory pre skrutky pre \u013eahk\u00e9 umiestnenie;
\nRozmery produktu: 32 (D) * 20 (W) * 22 (V)
\n8, m\u00e1 dlh\u00fa \u017eivotnos\u0165 a spo\u013eahliv\u00fa stabilitu
\n9, charakteristiky r\u00fdchlej regener\u00e1cie<\/p>\n

Elektrick\u00fd v\u00fdkon:
\nVstupn\u00e9 nap\u00e4tie: DC5V Spotreba energie (pr\u00fad): 150mA
\nDO v\u00fdstup: TTL digit\u00e1lne veli\u010diny 0 a 1 (0,1 a 5V)
\nAO v\u00fdstup: 0,1-0,3V (relat\u00edvne \u017eiadne zne\u010distenie), najvy\u0161\u0161ia koncentr\u00e1cia nap\u00e4tia je asi 4V<\/p>\n
