Smart Lights Controller

This is an ESP32-based IoT controller to turn a TP-Link Kasa HS100 smartplug off and on based on motion and sound. All code for this project is available on my GitHub. I made a video about the device, availabe below and on Youtube.

Software

All the files in the src directory of the GitHub repository were uploaded to the root directory of an ESP32 flashed with micropython firmware. The main components are:

the LightsController class, which orchestrates all operations of the device
the WiFi class, which connects the device to a WiFi network
the ClapMic class, which listens to input from the microphone
the (motion) Detector class, which listens to input from the motion sensor
the Kasa class, which handles communication with the smart plug
the (web) Server class, which hosts the user interface web page on the local network

Below is a screenshot of the user interface, available on the device's local wifi network.

Hardware

The housing for the device was 3d printed from the files in the CAD directory at the University of Maryland's Sandbox maker space.

The following components were used:

ESP32: HiLetgo ESP32 OLED WiFi Kit (with the original display removed)
Microphone: DEVMO Microphone Sensor
Motion detector: HiLetgo HC-SR501 PIR Infrared Sensor
Display: UCTRONICS 0.96 Inch OLED Module 12864
