Jul 16, 2021 · The DHT11 is a commonly used Temperature and humidity sensor that comes with a dedicated NTC to measure temperature and an 8-bit microcontroller to output the values of temperature and humidity as serial data. You can buy DHT11 sensor module from here.

Learn how to program Arduino to read temperature and humidity from DHT11 sensor and module. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino.

You need to follow these instructions to make it work: 1. You need to add the library to the Arduino IDE. 2. Upload the code. 3. When the code is uploaded, open the Serial Monitor and set the baud rate to 9600. 4. You will see the humidity and temperature. Don't forget to add this library to the Arduino IDE.

With just a few connections and a bit of Arduino code, you can begin measuring relative humidity and temperature right away. At the heart of the module is the digital temperature and humidity sensor manufactured by AOSONG – DHT11. DHT11 can measure temperature from 0°C to 50°C with a ±2.0°C accuracy, and humidity from 20 to 80% with a 5% accuracy.

May 21, 2024 · A resistive type humidity sensor, an NTC (negative temperature coefficient) thermistor (to measure the temperature) and an 8-bit microcontroller, which converts the analog signals from both the sensors and sends out single digital signal.

Nov 4, 2016 · The KY-015 Temperature and Humidity Sensor module provides a digital serial interface to measure environment humidity and temperature. Compatible with various microcontrollers like Arduino, Raspberry Pi and ESP32. This module consist of a DHT11 digital humidity and temperature sensor, a 1 kΩ resistor and 3 male header pins.

Oct 1, 2015 · In this tutorial, I’ll first go into a little background about humidity, then I’ll explain how the DHT11 measures humidity. After that, I’ll show you how to connect the DHT11 to an Arduino and give you some example code so you can use the DHT11 in your own projects.

DHT11 sensor provides relative humidity value in percentage (20 to 90% RH) and temperature values in degree Celsius (0 to 50 °C). DHT11 sensor uses resistive humidity measurement component, and NTC temperature measurement component.

May 17, 2022 · DHT11 Module features a temperature & humidity sensor complex with a calibrated digital signal output. The exclusive digital-signal-acquisition technique and temperature & humidity sensing technology ensure high reliability and excellent long-term stability.

In this tutorial you will learn how to use a DHT11 Temperature and Humidity Sensor with the Arduino, what is DHT11, difference between DHT11 and DHT22, DHT11 circuit diagram with the Arduino, and how to write Arduino code to read DHT11 Temperature and Humidity.
