my undergraduate graduation project

Alarm System for Intrusion Detection Based on ToF LiDAR

Hardware

I used self-designed PCB, but you can make some modify to run on your projects.

• ESP32-WROOM-32E
• SKP20 ToF LiDAR * 2
• 2.8 inch ST7789V TFT
• rotary encoder
• NPN MOSFET with buzzer and LED
• IP5108 Power SoC
• Li-ion battery (2000-5000 mAh)
• A switch to toggle the power connection

Compile

1. use git clone this repo

2. download vscode and platformio extension

3. if you only want to have a look on the lvgl ui, just open the lvgl_simulator folder (only verified on macOS)

4. if you want the firmware run on ESP32 open WirelessAlarmSystem folder

   • wait for platformio download dependent librarys complete

   • use git restore the files here (TFT_eSPI and lvgl)

   • for upload firmware via serial your ESP32 board need auto program circuit

Usage

1. scan the qrcode on TFT screen connect to the ESP32 AP or use password 12345678
2. waiting for the captive portal response or just visiting 192.168.4.1
3. setting up ESP32 Wi-Fi connection, MQTT broker domain(IP) and port
4. All the settings are saved on LittleFS filesystem, named config.json, you don't need to set up again on next boot
5. There is a web page for devices management hosting on cloud server, but the code I wrote was so bad, so I didn't open soure it 😢 (the mqtt broker uses emqx)
