Njira Yotumizira
Njira YobwezeraMphatso Yaulere
Takulandirani ku Roymall, webusaiti yanu yapadera yogulira mphatso zapadera. Timathamangitsa ndikuyamikira thandizo lanu, ndipo tikufuna kuyamika chifukwa cha kuwonjezera chisangalalo cha mphatso yaulere pa gulilo lililonse lomwe mungapange. Mukagula nafe, simungapeze zinthu zapamwamba zokhazikika zomwe zimakulitsa moyo wanu kokha, koma mudzapezanso mphatso yapadera yaulere ndi odala yanu. Mukonzeka kufufuza msonkhano wathu ndikupeza mphatso zanu zapadera? Yang'anani msonkhano wathu wa zinthu zapadera, ikani odala yanu, ndikuyembekeza mphatso yanu yaulere kuti idze ndi gulilo lanu.Njira Yotumizira
Timagwira ntchito yotumizira zinthu kwa inu mutalandira maodala ndikulimbikitsa kuti zidze bwino. Zambiri zotumizira zidzapezeka mu imelo yotsimikizira.M'magawo ambiri, maoda amakonzedwa mkati mwa masiku 2.Pansi pazochitika zapadera, zidzachepa motere: Mukapanga odala pa Loweruka, Lolemba kapena m'mabwalo a boma, zidzachepa kwa masiku 2.Mwambiri, zimafuna masiku 5-7 ogwira ntchito (Lolemba mpaka Lachisanu) popanda kukhudzidwa ndi kulephera kwa ndege kapena zina zokhudza chilengedwe.Chifukwa ntchito yotumizira yathu ndi padziko lonse lapansi, nthawi yotumizira idzakhala kutengera komwe muli kotero zingafune nthawi zina ndikuyembekezera ngati muli m'matawuni kapena m'maiko akutali.1. Njira Yobwezera & Kusintha
Timagwirizana ndi zinthu zomwe zinagulidwa kuchokera ku roymall.com. Ngati mwagula kuchokera kwa ogawa zathu kapena ogulitsa ena, simungabwezere ife. Zogulitsa zamalonda kapena mphatso zaulere sizilandiridwa kuti zibwezedwe. Kuti mugwiritse ntchito kubweza, chinthu chanu chiyenera kukhala chosagwiritsidwa ntchito ndi kukhala momwe munalandira. Iyeneranso kukhala mu bokosi loyambirira.Mutatenga malangizo obweza kuchokera kwa ife, konzekerani zinthu zanu zobwezedwa ndikubweza bokosi lanu kuchipatala kapena wotumizira ena.Timakonza kubweza kapena kusintha kwa chinthu mkati mwa masiku 3-5 ogwira ntchito mutalandira. Kubweza kudzachitidwa ndikubwezedwa kwanthawi zonse kudzera munjira yanu yoyamba yolipira.Palibe kubweza kapena kusintha zomwe zingalandiridwe ngati chinthucho chinapangidwa mwachisawawa, kuphatikiza kukula kwachisawawa, mtundu wachisawawa, kapena kusindikizidwa mwachisawawa.Mukufuna thandizo lina, chonde titumizireni. service@roymall.com kapena Whatsapp: +8619359849471
2.Njira Yobwezera Ndalama
Mudzalandira ndalama zonse kapena 100% kirediti ya sitolo mutalandira ndikuyang'ana bokosi lobwezedwa. Kubweza kudzachitidwa ndikubwezedwa kwanthawi zonse kudzera munjira yanu yoyamba yolipira. Chonde dziwani kuti mtengo wotumizira ndi zina zilizonse kapena malipiro sali obwezeredwa. Mtengo wotumizira wowonjezereka sukupezeka kuti ubwezedwe mutabwera bokosi. Inu ndinu omwe muyenera kulipira malipiro awa ndipo sititha kuwaletsa kapena kubweza, ngakhale odala yabwerera kwa ife. Mutalandira ndikutsimikizira chinthu chanu chobwezedwa, timakutumizirani imelo kukudziwitsani kuti talandira chinthu chanu chobwezedwa. Tikudziwitsansinso za chilolezo kapena kukanidwa kwa kubweza kwanu.Ngati muli ndi vuto lalikulu pa njira yobwezera, chonde titumizireni. service@roymall.com kapena Whatsapp: +8619359849471

Principle:
The gas sensing material used in the MQ-5 gas sensor is tin dioxide with low conductivity in clean air. When there is flammable gas in the environment where the sensor is located, the conductivity of the sensor increases with the increase in the concentration of flammable gas in the air. big. External oscillator resistance 100K~240Ku03a9 (the larger the resistance, the slower the sound speed), the buzzer can be driven to sound after power-on. Pin 1 is grounded, pin 2 is output, pin 3 is the sound terminal, pin 4 is connected to the positive pole of the power supply, and pins 5 and 6 are connected to the shock resistance.
