IoT based Smart Notice Board using Node MCU
Call for Price
In this IoT project smart notice board is implemented using Node MCU
Building a IoT based projects gives the fast transformation of data and the user can access the data from anywhere in the world. In this project , we have developed a IoT based smart notice board. The main objective of this project is develop a automatic , self enabled and highly reliable electronic notice board . A display connected with the cloud will continuously waiting for the message from the user , if the user upload the data in the Thingspeak cloud, it will automatically uploaded to the LCD. By using NodeMCU ESP8266 , the user can upload the message to the LCD by accessing the Thingspeak IoT cloud . The user can write the data from anywhere in the world to the LCD. This will reduce the time to update the data as well as it will efficiently transfers the data’s to the end user.
This smart notice board is available in many educational institutions, banks and public places.This is done by using a microcontroller and GSM. By sending a message , the user can get the data in LCD display. So, the existing system uses GSM based notice boards.
In this project, we have developed IoT based smart notice board. Here , we are using NodeMcu ESP8266 and LCD display to show the data. NodeMCU is a low cost open source platform . By using NodeMCU we can connect to the the Wifi network. The user can write the data in Thingspeak cloud which they want to show in notice board. After writing the data , the end user can get these data’s in LCD displays. These displays more helpful in educational institutions , banks and public transports such as railways , airways etc.
