IoT Weather Station using DHT11 Sensor

In this session, I will show you how to make a simple IoT weather station using NodeMCU and DHT11 sensor. So, without doing any delay let's get started.

Components Required

 

let's start with everything that we need for this project. First of all, we need something to measure the temperature and Humidity, for that perfect match is the DHT11 sensor. You can also use DHT22 but it's a bit expansive compared to DHT11 senor. Next, we need a microcontroller board, but we cannot use any regular Arduino Microcontroller board. So, we will use NodeMCU ESP8266, which is based on the ESP-12E chip and has onboard WiFi capabilities. This is what we are looking for in this project because we are working on IoT.

 

Lastly, we need a 16x2 LCD Display with an I2C interface, for displaying the weather status like Temperature and Humidity. We already made a Tutorial on the same topic but, to make it more interesting. Today, We will add IoT features using the Blynk Application. We will be using the Blynk App along with its library to even display the Temperature and Humidity on your smartphone too.
