This project uses a PIR sesnor to detect motion using temperature changes which then sends a PWM signal to the Node MCU Which then sends data to adafruit cloud.We are using Adafruits Iot instead of ...

This project is an Intruder Detector using the Passive Infrared Sensor which is being used as a motion detector connected to Node MCU. PIR Sensor PIR sensors allow you to sense motion, almost always ...
