Someone please help in writing sensor data on 7 segment led display on arduino. I want to use the DHT11 to show the temperature and humidity on the 7 segment led display.

How many digits will you use to display? Is the display a pre-manufactured one? These questions are needed to know how to display the data. You will have to write code to multiplex each digit.

Then, is the display a common anode or common cathode type? You will need to know this to determine how to connect the 7segments to the Arduino.

The output of the DHT11 are float values. You will need code to convert the float value into individual digits. They can be integers or char and must be mapped to an array of 7-segment values (on or off)
