Arduino Temperature And Humidity Sensor Code

I didnt have any trouble interfacing the arduino lcd and the dht11 sensor and my codes were quite right since when i run it nothing s odd in the output.

Arduino temperature and humidity sensor code.

This project is really simple and shouldn t take us very long. I checked my. In this project we will use the ky 015 arduino dht11 temperature humidity sensor and display it to the arduino ide serial monitor. Humidity sensor dht22 the dht 22 also named as am2302 is a digital output relative humidity and temperature sensor.

My project displays the temperature and humidity on an lcd1602 module. Today through this post i will tell you how to build the temperature sensor project or weather station with the help of arduino. By combining a temperature and humidity sensor with a small lcd you can create a cheap weather station. In the following example i will be using an i2c character lcd like this one from amazon.

We define global variables for the temp and humidity values we define variables for 2 timers one for the sensor read time and one for an animation on the lcd the refresh value in the webpage code was changed from 1 to 30 to make the refresh 30 seconds vs every second. Arduino temperature and humidity sensor code circuit diagram etc temperature and humidity readings are measured by the help of arduino uno and dht11 sensor. The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino. Serial communication is archived by sending specific high low signals to the sensor and waiting for a response.

Arduino temperature sensor. But when i connect the relay in which an ac device is connected as an output that turns on after a couple of minutes the temperature and humidity dislayed on the lcd becomes odd like chinese and numbers after some time. Dht 11 sensor dht module. First collect these.

It s very simple to build. The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino. The following sketch uses pin 8 on the arduino to serially send and receive data from the ky 015 sensor. Learn how to use temperature and humidity sensor with arduino how to connect dht11 or dht22 temperature and humidity sensor to arduino how to program arduino step by step.

This line could be removed if you don t want the page to auto refresh or increased to make the refresh time longer. In this example you will learn how to use this sensor with arduino uno. How to use arduino to read temperature and humidity from sensor and display temperature and humidity on lcd how to combine dht11 dht22 code and lcd code how to program arduino step by step. Dht11 temperature and humidity sensor 3pin.

Arduino uno any uno will work i have a geekcreit uno. Temperature and humidity data is read bit by bit and returned as an array of bytes. Example code for dht11 and dht22 am2302 temperature and humidity sensor with i2c lcd and arduino.
