Development of smart human machine interface for solar powered appliances

This paper presents a low cost smart human machine interface (HMI) solution designed for solar powered home appliances and industrial units. The underlying concept behind the design and development of such a device is the growing convergence between communication equipment, appliances and industrial devices. A large number of appliance and industrial manufacturers now need advanced control and insights into their existing solutions for providing added ergonomics in their product and increase overall customer interest and therefore the product life. The HMI solution developed here is one such platform which has the ability to be integrated to a variety of logging, connectivity, monitoring, control and e-commerce based web applications. Certain individual hardware and software modules can be added to the existing HMI to enhance functionality.
