Dht11 temperature and humidity sensor with arduino.

Arduino dht11 temperature humidity sensor code.

The dht 11 is a digital output relative humidity and temperature sensor. Display humidity and temperature on the serial monitor. It measures both moisture and air temperature. In these tutorials we will measure temperature and humidity by using dht11 with arduino.

It s accurate enough for most projects that need to keep track of humidity and temperature readings. The materials are here as follows. Arduino uno read best arduino starter kits. Include dht h including the library of dht11 temperature and humidity sensor define dhtpin 2 selecting the pin at which we have connected dht11 define dhttype dht11 selecting the type of dht sensors dht dht dhtpin dhttype.

This project is really simple and shouldn t take us very long. In this tutorial we will learn how to use a dht dht11 version temperature and humidity sensor. The dht11 temperature and humidity sensor senses measures and regularly reports the relative humidity in the air. Arduino uno any uno will work i have a geekcreit uno.

The room temperature humidity will be printed to serial monitor. Here we also display those readings on an lcd display. Void setup serial begin 9600. The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.

Before you can use the dht11 on the arduino you ll need to install the dhtlib library it has all the functions needed to get the humidity and temperature readings from the sensor. To complete this tutorial you need the following components. 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. In this section we ll build a simple project with the arduino that reads temperature and humidity and displays the results on the serial monitor.

It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin. 10k ohm pull up resistor. Again we will be using a library specifically designed for these sensors that will make our code short and easy to write.
