Today I will show you how to make Arduino Temperature Humidity sensor project with LCD module. Before starting this project, I want to tell you guys about my recent project in which I made Alcohol tester with Arduino. You can also make this test at home at very low price.
What is Arduino Temperature Humidity Sensor?
You may know about Temperature Humidity Sensor, if you don’t know about it here, I will tell about it.For Arduino, there is available two type of sensors DHT11 and DHT22. In this project, I am using DHT11. DHT11 is essential Temperature Humidity Sensor and low-cost digital sensor. It uses a capacitive moisture sensor and a thermistor to regulate the surrounding atmosphere. its simple to use and it takes data in 2 sec real time. After every 2 sec update data and give to you like the digital signal.
How to make Arduino Temperature Humidity Sensor Project:
You can easily create weather station at home using temperature humidity sensor with Arduino. For this project, you need a DHT temperature sensor, For output, you may require LCD module and An Arduino controller for this project.
You may need:
- Arduino Mega OR UNO Board.
- Temperature Sensor DHT11 OR DHT22.
- Keypad Shield 1602 Board
- Some wires.
- 5v adapter or power bank.
Now you need to wiring up hardware with each other. Here is the wiring diagram you can see below.
You have to connect DHT11 on pin 22 Digital.
Another thing is Connecting Keypad LCD Shield attach it as below in the image.
when you are wiring up all things correctly then you have to upload the code.
Source Code & Library:
For DHT11 you need adafruit DHT11 library download from here. Install the library on you Arduino IDE, and next step is to download the main code for this project.Main Code
Simply upload the main code on your Arduino board and you all done… 😀 your weather station is ready 🙂
Note: IF you don’t know how to add library and upload code to Arduino. You can read my previous project where I briefly described it.
Performance update regarding DHT11:
DHT 11 not much accurate as DHT 22. If you need an accurate forecast, then use a DHT22 sensor for good result.
You can buy all the stuff online at the very low price if you need any help regarding this let me know in the comment, I will find out lowest cost link for you. 😀
