Interfacing DHT11 Temperature and Humidity Sensor with Arduino Uno

In this tutorial we will learn about Interfacing DHT11 Temperature and Humidity sensor with Arduino Uno. The term DHT is an abbreviation of Digital Humidity and Temperature sensor. DHT11 consists of a resistive humidity sensor, NTC temperature sensor and an 8-bit microcontroller providing cost effectiveness, anti-interference ability, excellent quality and fast response.

Interfacing DHT11 Sensor with ESP8266

In this article, I am going to explain about interfacing of DHT11 sensor with ESP8266. For that we have to make only 3 connections between the DHT11 sensor and ESP8266. For the working demonstration we will be programing ESP8266 as a web server for displaying temperature and humidity in a web browser as per request. Components Required ESP8266 DHT11 Sensor USB Cable Connecting Wires Hardware Circuit Diagram Interfacing DHT11 Sensor with ESP8266 - Circuit Diagram Connections DHT11 sensor (+) pin will be connected to 3.3V DHT11...

Temperature and Humidity Data Logger using Arduino

In this project, we are going to make a temperature and relative humidity data logger. Arduino is the brain of this project. DHT22 sensor is used for sensing temperature and relative humidity. Arduino Uno is programmed to read temperature, humidity values from DHT22 sensor and save it to a file in an SD Card. So whenever required we can take the SD Card for viewing data. Here we will take data from SD card and import it to excel...
