Microcontroller (MCU) with built in WiFi
Introduction
IoT is subject about connecting devices to the internet so that they can send/receive data, accept commands remotely through web pages or cloud applications. For example, one can turn on Air conditioning units remotely using a smartphone app, or a doctor can receive bio health information for his patient on his smartphone.
In order to achieve that the following components are required
- Internet connectivity
- A Microchip capable of communicating to internet, preferably using WiFi
- A Microcontroller with memory to run a program for communication
- Some additional hardware to control the device.
There are also Microchips that are Microcontrollers as well as WiFi adapters. Here are some examples.
