Smart devices using NodeMCU

Li2 welcomes you to the exciting world of smart devices.

Smart devices have taken the modern world by storm, with devices like smart watches, smart phones, and smart speakers, which connect to a wireless network and give you access to a variety of functions at your fingertips.

This two day hands-on workshop involves building a smart device using advanced sensors and ESP8266 NodeMCU, in fields of Agri-tech, Healthcare and Home automation. The workshop will introduce concepts like IFTTT, MQTT, and Wifi in Access point and Station modes, incorporating hands-on experiments and real-time problem solving.
