DHT11 sensor measures and provides humidity and temperature values serially over a single wire.
It can measure relative humidity in percentage (20 to 90% RH) and temperature in degree Celsius in the range of 0 to 50°C.
It has 4 pins; one of which is used for data communication in serial form.
Pulses of different TON and TOFF are decoded as logic 1 or logic 0 or start pulse or end of frame.

Step-2! Now You Have to need Download DHT library and Include Ardunio Board Following Instruction
Dht Library add-Mechatronicslabrpi
create a Project use Blynk apps Following Instruction
First LogIn your Blynk App Then Flow the Step By Step
Step1 -Create A New Project
Step2- Select Your project name and Board(I Select Name DHT Monitoring System and Bord NodeMcu) then Press Create
Blynk give Name-Mechatronicslabrpi
Step3 -This is vary important Step Hear you got your AUTH TOKEN it send to your email address. Press OK
Blink Auth Token-Mechatronicslabrpi
Step4- Now you can see your Interface like this
Blynk interface -Mechatronicslabrpi
Step5-Now go to Widget Box And select Gauge
Blynk Waidget Box-Mechatronicslabrpi
Step6- After Two Gauge select See like this interface
Blynk Set Gase-Mechatronicslabrpi
Step7- Now Go to Gauge settion and Select the neme, Input, Reading (Hear i select Name Temperature, Humanity Input= V0,V1 and Reading Rate 1 Sec )
Step8- After Given Information show like this
Step9-Now Again go to Widget Box and select SuperChart
Step10- Now go to SuperChat Setting set Name, DataStrme (I Select Name=Temperature & Humanity DataStrm =Temperature , Humanity )go to dataserm setting set input V0 for Temperature V1 for Humanity
App setting Completed
