Introduction: Nodemcu With OLED Display, PIR & DHT11
Step 1: Introduction:
In this project we are going to build a system which shows temperature and the motion on oled display.
The project is easy to build and implement.
Let Start making it.......
Step 2: Collect Components:

3. DHT11 or DHT22
4. PIR sensor
5. Resistor 4.7Kohm
Step 3: Gathering Required Libraries:
All the libraries are available on github.
Step 4: Schematic:
Step 5: Code:
