Chipata cha LORAWAN cha MKG-3L
Kufotokozera Kwachidule:
MKG-3L ndi chipata chamkati cha LoRaWAN chotsika mtengo chomwe chimathandiziranso protocol ya MQTT. Chipangizochi chingagwiritsidwe ntchito pachokha kapena kuyikidwa ngati chipata chowonjezera chophimba chokhala ndi mawonekedwe osavuta komanso osavuta kumva. Chimatha kulumikiza netiweki yopanda zingwe ya LoRa kupita ku ma netiweki a IP ndi ma seva osiyanasiyana a netiweki kudzera pa Wi-Fi kapena Ethernet.

Chipatachi chili ndi kapangidwe kokongola komanso kamakono, ndipo chimathandizira kukhazikitsa khoma ndipo chingagwiritsidwe ntchito mosavuta kulikonse mkati kuti chitsimikizire kuti chizindikirocho chili ndi malo okwanira.
MKG-3L imapezeka m'mitundu itatu motere:
| Chinthu Nambala | Chitsanzo | Kufotokozera |
| 1 | MKG-3L-470T510 | Bandi yogwiritsira ntchito ya LoRa ya 470~510MHz, yoyenera bandi ya LPWA ya ku Mainland China (CN470) |
| 2 | MKG-3L-863T870 | Bandi yogwirira ntchito ya LoRa ya 863~870MHz, yoyenera magulu a EU868, IN865 LPWA |
| 3 | MKG-3L-902T923 | Bandi yogwirira ntchito ya 902~923MHz LoRa, yoyenera magulu a AS923, US915, AU915, KR920 LPWA |
Mawonekedwe
● Imathandizira Wi-Fi, 4G CAT1 ndi Ethernet
● Mphamvu Yotulutsa Kwambiri: 27±2dBm
● Mpweya Wopereka: 5V DC
● Kuchita bwino kwambiri, kukhazikika bwino komanso mtunda wautali wotumizira
● Kusintha kosavuta kudzera pa intaneti mutalumikiza ku Wi-Fi kapena adilesi ya IP ya chipangizocho
● Mawonekedwe ang'onoang'ono, okongola komanso osavuta kuyika pakhoma
● Kutentha kwa Ntchito: -20°C mpaka 70°C
● Imathandizira LoRaWAN Class A, Class C ndi protocol ya MQTT yaumwini
● Band Yogwirira Ntchito: Kuphimba kwa bandi yonse ndi ma frequency osankhidwa ogwirira ntchito
