The dht11 temperature and humidity sensor senses measures and regularly reports the relative humidity in the air.
Dht11 temperature and humidity sensor module for arduino.
It s very simple to build.
In these tutorials we will measure temperature and humidity by using dht11 with arduino.
It measures both moisture and air temperature.
The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.
This module consist of a dht11 digital humidity and temperature sensor and a 1 kω resistor.
We ll explain how it works show some of its features and share an arduino project example that you can modify to use in your own projects.
Dht11 digital temperature and humidity sensor is a calibrated digital signal output temperature and humidity combined sensor which application specific modules capture technology and digital temperature and humidity sensor technology to ensure that products with high reliability and excellent long term stability.
Here we also display those readings on an lcd display.
It s perfect for remote weather stations home environmental control systems and farm or garden monitoring systems.
Dht11 module hardware overview.
Complete guide for dht11 dht22 humidity and temperature sensor with arduino this article is a guide for the popular dht11 and dht22 temperature and humidity sensors with the arduino.
In this tutorial i ll first go into a little background about humidity then i ll explain how the dht11 measures humidity.
Arduino uno any uno will work i have a geekcreit uno.
The dht11 uses an internal thermistor and a capacitive humidity sensor to determine environment conditions an internal chip is responsible for converting readings to a serial digital signal.
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.
Dht11 temperature and humidity sensor 3pin.
Dht11 can measure temperature from 0 c to 50 c with 2 0 c accuracy and humidity from 20 to 80 with 5 accuracy.
In this project we will use the ky 015 arduino dht11 temperature humidity sensor and display it to the arduino ide serial monitor.
The dht11 humidity and temperature sensor makes it really easy to add humidity and temperature data to your diy electronics projects.
The materials are here as follows.
My project displays the temperature and humidity on an lcd1602 module.
