It　is　an　intelligent　face　recognition　access　control　system　based　on　OpenMV,　Arduino,　RC522,　Esp8266　WiFi　module　and　Ali　Cloud　Internet　of　Things.　It　provides　users　with　three　ways　to　enter　their　homes,　including　face　recognition,　NFC　recognition　and　micro　program　wechat　lock.　Face　recognition　uses　OpenMV　and　Arduino　to　accurately　recognize　faces　with　the　help　of　LBP　eigenvalues.　RF　module　uses　RC522,　with　access　card　can　achieve　the　purpose　of　entering　the　residence,　to　provide　convenient　access　for　visitors.　In　the　part　of　Internet　of　Things　and　wechat　Applet,　Esp8266　WiFi　module　and　Ali　Cloud　Internet　of　Things　are　used　to　build　the　whole　Internet　of　Things　system,　so　as　to　build　we　chat　small　program　to　realize　the　function　of　opening　the　door,　realize　the　information　exchange　between　users　and　electromagnetic　lock,　and　ensure　the　non-contact　unlock　under　the　epidemic　situation.　Three　ways　to　enter　the　residence　give　users　free　choice　and　provide　a　greater　degree　of　convenience.　©　2022　IEEE.
