IoT (Internet Of Things) Motion Sensor – A motion sensor which will give us push notification in our phone whenever a motion is detected made using NodeMCU ESP8266 and PIR.
PIR + Relay, Motion activated switch PCB Gerber file.
Lets make a motion activated switch using PIR sensor, BC547 transistor and 5v relay.
In this project, we are going to learn how to make an IoT motion sensor which will give us alert on our phone when motion is detected at the place we installed the sensor. Everything works through the internet so there is no limitation of distance between the sensor and the phone.
