OFweek smart home network news in the process of home intelligence, in fact, switches and sockets are essential basic products, in a set of smart home systems, it is impossible to reduce the smart switch this one basic product. The intelligent switch refers to the unit that uses the combination and programming of the control board and the electronic components to realize the intelligent switch control of the circuit. At present, it has been widely used in many fields such as intelligent home renovation, intelligent office renovation, industrial intelligent transformation, and intelligent agriculture and forestry fishery and animal husbandry. I previously introduced the smart socket solution based on the WiFi module. This article will introduce the smart switch solution based on the WiFi module.
WiFi module intelligent switch solution
