The DHT11 sensor is digital that is provides data in digital form it is opposite to thermistor whose values for temperature measurement are analog in nature. It is important to note here that this sensor measures both the temperature and humidity simultaneously that is on each request for data from the microcontroller the DHT11 sensor generates the data packets containing the information about both the temperature and humidity. So sit back, keep reading and enjoy learning.īefore diving deep into the discussion on the interfacing of the Arduino microcontroller development board and DHT11 sensor let us first what the DHT11 sensor is? DHT11 sensor is used to measure the temperature and humidity of the surroundings in which it is installed. The discussion in this post about the interfacing of the DHT11 sensor and Arduinois general so that the text can help to hook up any sensor with the Arduino microcontroller.
This post will be oriented around the discussion on the DHT11 sensor only.Īfter reading this post the reader will be able to learn about the DHT11 sensor and its interfacing with Arduino. In the previous posts I have discussed about the working of important sensors and actuators and their simulation in Proteus. In this post I will discuss about the DHT11 sensor and its interfacing with Arduino.
