IOT Projects Using NodeMCU | ESP8266

Internet of things is the coming together of internet and physical devices in a network of unlimited possibilities. IOT allows for physical devices to wirelessly communicate over networks which has led to a growing number of applications for iot devices.

What is NodeMcu ?

NodeMcu is a very affordable and opensource Internet of things development platform to speed up IOT development. It is an IOT development kit running on ESP8266 Wi Fi SoC. The term NodeMcu is a combination of a network Node and Mcu (Microcontroller). This development board focuses on IOT based device firmware.

NodeMcu Specifications

  • Operating Voltage: 3.3V
  • Input Voltage: 7-12V
  • Digital I/O Pins(DIO): 16
  • Analog Input Pins(ADC): 1
  • Flash Memory: 4 MB
  • SRAM: 64 KB
  • Communication: UART | SPI | I2C
  • Clock Speed: 80 MHz

What is ESP8266 ?

ESP8266 is a low cost Wifi Module that integrates TCP iP stacking with microcontroller processing. It is also used on NodeMcu and is practically used to bring wifi networking capabilities to an electronic component/device. It is the most widely used component in iot projects and has lots of iot applications by adding wifi capabilities.

ESP8266 Pinout

  • VCC – (+3.3 V; can handle up to 3.6 V)
  • GND – Ground (0 V)
  • RX – Receiving Data
  • TX – Data Transmission
  • CH_PD – Power Down Mode
  • RST – Reset Module
  • GPIO 0 – General Purpose IO
  • GPIO 2 – General Purpose IO


ESP8266 and NodeMcu are frequently used to develop a wide variety of iot devices and diy projects. Here are some of the top diy projects made using nodemcu and esp8266 wifi module. This has led to the growth of internet of things in many applications including consumer electronics, automotive, industrial, smart cities etc.

IOT Theft Detector Energy Meter
wheelchair fall detector
Smart energy meter that transmits energy meter readings directly over internet along with a theft detection feature to detect energy thefts with ease.
IOT Temperature Mask Scan Entry System
IOT Mask scan entry
Manual mask and temperature is a tiring an not accurate system for large crowds. So here we automate the system using thermal sensors and camera for automatic safety check entry.
IOT Smart Garbage Segregator
IOT smart garnage segregator
An important step in grabage recycling is garbage segregation. To ensure people dispose garbage in segregated way this raspberry pi based project provides and innovative way to do it.
IOT Wheelchair Fall Detector & Alert
wheelchair fall detector
A useful IOT project to help the elderly/disabled send automatic alert if they fall so help arrives instantly. Using microcontroller based circuitry with interfaced sensors.
IOT Gas Leak Detector & Auto Exhaust
IOT gas leak detector
An Arduino IOT project to avoid fire accidents itself using gas sensors to detect & automatic exhaust fans to suck out the gas. Instantly monitor gas levels over IOT & trust it to sefegurd against any gas accidents.
IOT Smart Dustbin
IOT smart bin
In this smart age why should your dustbin be dumb. Just tap your feet to open the bin & get IOT status of bin garbage levels through wifi using the IOT smart dustbin project.
