Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: INTRO

This device incorporates seven segment displays as output for the value of temperature and humidity to be displayed.

The two seven segment displays works on the principle of multiplexing which saves a lot of I/O pins on Arduino and a lot of coding time.

There is also a switch to choose if you want to view temperature or humidity according to your choice.

Step 2: Items Required

The items required are :-

1. 2 X 7 Segment Displays (COMMON ANODE)


3. 1 X DHT11 Humidity And Temperature Sensor

4. 1 X ARDUINO (UNO,Mega,Nano etc.)

5.1 X Perfboard/BreadBoard

Step 3: Circuit Diagram

Follow the circuit diagram as described in the image.

Step 4: CODE

Upload the code given to your Arduino and your device should work.
