MotionLED

A NodeMCU ESP8266 project for controlling 12V LED strip. I added a motion sensor to the mix as I had one. This project uses MQTT to communicat with Home Assistant, I used this project for my kitchen cupboards.

Implemented Features:

• MQTT to turn on/off LED strip
• MQTT to set the brightness of the LED strip
• PIR sensor that publish MQTT motion events.
• Over-the-Air (OTA) Upload from the ArduinoIDE!

Parts

I'm using the following parts for this project

• NodeMCU ESP8266
• IRF540N: N-Channel Mosfet
• AM312 PIR motion sensor
• 12V Power Supply
• DC-DC Buck Converter
• Logic Level Shifter
• 12V White LED Strip
• Some 2.1mm DC Jacks and sockets
