The Key hardware ingredients to develop IOT Embedded system/unit

When the software and network protocols both wired and wireless support remote smartphones app based control of electronic hardware and integrated system, equipment, tools and consumer gadgets, there is innumerable opportunity to develop products for every electric-powered operated application all the way from your simple home appliance to industrial controls.

In the trillion dollar global market opportunity, you can find highly  crowded suppliers in most of the segments yet there are areas where you still find some market opportunity to serve where you can compete on cost,  performance ,reliability and better customer support.

Let's look into basic hardware requirements to develop such a product. 

Typical IoT based embedded board / system contain , a MCU/processor/SoC, wired and wireless/RF interface, sensor and analog signal chain, power electronics, and some additional control  circuitry. Through this Internet/network connecting embedded board, you can switch on/off an external system by using electromechanical switch,  power transistor, thyristor, or a solid state relay.  You can control motor speed and power.You can control linear and circular motion by using specialized motors such as stepper motors and many such...
