Samsung is revitalizing its existing appliances with the exciting new 'Smart Fo

The Internet of Things (IoT) has gained huge traction in the past couple of years and this sophisticated technology has been adopted largely across several industries and for several use cases.

Smart homes have become popular due to their convenience and energy efficiency. An implemented project uses voice commands to wirelessly control home appliances and lights.

Zigbee is a standard protocol for wireless networking that mainly addresses the need for low-power devices with a low data rate for short-range communication.

Conventional energy meter which we use in our households to measure Energy consumption is an offline device, so it has to be monitored manually.

Every Marvel fan would have envied of having his/her personal assistant like JARVIS to get things done on their voice command.

“Ok Google Do my homework” – If this command worked, our childhood would have been simple, isn’t it? But some things are meant to be done by ourselves and of course, we are not going to design something that does your homework.

Here we are building an IoT water level monitoring system using a float level sensor and NodeMCU ESP8266 to monitor the level of water and publish it on a web-server.

Home automation now becomes an essential part of IoT applications and people use their smartphone to control home appliances from anywhere over internet.

In previous tutorial, we built an Alexa controlled Home Automation system using NodeMCU. It was easy to build and implement.
