The NodeMCU is an open-source firmware and development kit that helps you to prototype your IoT product within a few Lua script lines.

Lowest cost microcontroller WIFI Board. The Development Kit is based on ESP8266, integates GPIO, PWM, IIC, 1-Wire and ADC all in one board. Costs 10 times less than the original Arduino shield. You can build IoT things and send the data in real time over wifi.

The option to send data wirelessly enables countless possibilities. I myself have been thinking about creating a smart-home, you can connect anything to your network, even make it globally available. With simple web server you can make it possible. Even control electricity in your home with relays, the possibilities are endless. The first things that come to mind are checking if your plants need watering, switch lights on and off, the security implementations or ride with a remote control car remotely on you mobile phone to check things out at home or annoy your pets.
