So today in this blog we are going to discuss the ultrasonic module HC-SR04, which is quite famous among the Arduino or raspberry pi geeks.  So in this blog, you can able to see how the module works and how to interface that with any kind of projects.SO let's dig into it- Internal structure -  This module is packed with an ultrasonic transmitter and an ultrasonic receiver as well as the controller circuit. Though this module packed with many components it is very compact in design, This module has only 4 pins Pin details- 5 v supply (VCC) Trigger pulse pin (input) Echo pulse pin (output) Ground (GND) How it works- Ultrasonic ranging module is mainly used to measure the distance between some object and the module. It has an ultrasonic transmitter and a receiver, it basically generates a pulse of ultrasonic sound and then the module's receiver part listen the sound reflected by the target object. And after that using a simple formula of physics is applied

So today we are going to make a weather station which is powered by An Arduino nano.Which can monitor the live temperature and humidity of the climate? And also print the data on an LCD display.By this project, you can easily understand the working of the DHT 11 sensor and LCD display. So to make this project you need this component:- Arduino board (any types of) LCD 16X2. DHT 11 module Connecting Wire Breadboard(optional) What is DHT 11 MODULE? DHT 11 or 22 are the digital humidity and temperature sensing module for Arduino, avr, raspberry pi.Adafruit industries basically made this sensor.This module is the low-cost humidity and temperature sensor which has only one pin to transfer the data. So it required a careful timing to grab the data sent by it. But its very simple to use/interface with any kind of projects. We basically need the libraries to use it properly.It speaks the data after 2 sec. The cost of this kind of sensors is near about 3-4 $. But DHT 22 is m
