#DHT11 FLOW SENSOR LIBRARY FOR PROTEUS 8 HOW TO#

As the humidity level changes, the resistance between both of the electrodes or conductivity also changes correspondingly.

The humidity part consists of two electrodes having moisture-holding substrates in between them.

For humidity sensing, DHT11 uses a capacitive humidity sensor.

I have provided a visual display of the relation between temperature and resistance for the DHT11 sensor, shown in the below figure:.

NTC means the resistance decrease with the increase in temperature.

A thermistor is made up of sintering of semiconductors in order to provide a large change in its resistance with the small changes in temperature.

A thermistor is simply a variable resistor, which changes its resistance with respect to the temperature.

In order to measure temperature, DHT11 uses a thermistoralso known as NTC (Negative Temperature Coefficient) temperature sensor.

DHT11 pin description is provided in the below table:.

Pin#4: GND: Need to provide ground to this pin.

Pin#3: NC: ItвЂ™s an open pin and is not connected to anything(For future use).

Pin#2: Out: Output Pin for reading DHT11 data.

Pin#1: Vcc: We need to provide +5V to this pin.

Before using any electronic device we must know about the functions of its all pins.

DHT11 along with its pinout is shown in the figure given below.

It is used in home appliances, weather stations, medical humidity control, data loggers, HVAC and at several security places.

DHT11 measures the relative humidity of the surrounding.

It is a low-cost sensor but provides precise results and it gives value once every 2 seconds.

It has both a capacitive humidity sensor and a thermistor embedded in it.

DHT11В is an electronic sensor, consists of 4 pins and is used to measure the temperature and humidity of the surroundings.

You can also design a complete project on interfacing of more than one temperature sensors by taking help from Interfacing of Multiple DS18B20 Arduino.

I have also written detailed tutorial on Interfacing of TemperatureВ Sensor 18B20 with Arduino, so you should have a look at this article.

In my previous tutorial, I have shared Interfacing of LM35 with PIC Microcontroller, so you should first need to go through this article.

I have also shared a complete detailed article about How to use 18B20 in Proteus ISIS.I have shared the Interfacing of LM35 with Arduino in Proteus ISISВ in my previous tutorial.the further detail about DHT11 Arduino Interfacing will be given later in this tutorial. home appliances, weather stations, consumer goods etc. In real life DHT11 can be used at several different places e.g. DHT11 has a lot of features including low cost, long term stability, fast response time, excellent quality, long distance signal transmission and many more. It has four pins whose detail will be explained later.

It can transmit the signal up to 20 meters. It has a small size and low power consumption. It provide precise results with the higher efficiency. This property makes it more popular among the similar type of sensors. DHT11 is a low cost sensor and is easily available in the market now a days. LM335 is another temperature sensor and to understand todayвЂ™s post more properly, you should also go through Introduction to LM335. This digital signal can be read easily through any micro-controller. There is a small chip inside this sensor which performs the function of analog to digital to analog conversion and gives the results for temperature as well as for humidity in digital form.

DHT11 is a slow sensor but is quite efficient for the applications where we need to do some basic analog data exchange. capacitive humidity sensor and a thermistor. It is made up of two different parts i.e. DHT11 is an embedded sensor, used to measure both temperature and humidity of the surroundings. Today, we will have a look at the DHT11 Arduino Interfacing. Hello everyone! I hope you all will be absolutely fine and having fun.
