Design of ICRD multifunctional cold water recovery system based on the Internet of Things technology

In order to solve the problems of early cold water recycling of traditional water heater, single function and poor use experience, a cold water recovery system with hot water return, temperature regulation and private customization is designed. The system uses S TM32 single chip machine as the control core, and through clever mechanical design realizes cold water recovery through the cold water recovery module, remote control module and hot water temperature control module. At the same time, for the system developed a special App, water heater, faucet and bathroom lighting linkage, using a mobile phone can control the water heater water temperature, flow speed, bathroom lighting atmosphere, bath center, and so on, so can greatly improve the user water experience, in line with the concept of smart home, improve water utilization, promote the development of resource-saving society.
