# 基于 Raspberry Pico / Pico W (RP2040 FreeRTOS) 的厨房危险(火灾)报警 (Pico W WiFi传输暂时不玩) * 使用 DS18B20温度传感器 * 使用 CH4 N55A甲烷气体传感器(进口) (弃用) * 使用 PASCO2V01 CO2二氧化碳传感器模块(进口模块暂时买不到!) * 使用 MH-Z14B CO2二氧化碳传感器模块(国产)(0 - 5000ppm) * 使用 ZE07-CO CO一氧化碳传感器模块(国产) * 使用 HC-12 433MHZ传感器模块(国产) * 使用 ZC05/ZC13 可燃气体(天然气 CH4)传感器模块(国产) ## 源码构建 ```bash # 使用WSL Debian GNU/Linux 12 (bookworm) 构建 # 确保Pico-SDK环境变量 export PICO_SDK_PATH=/mnt/c/Users/niuyuling/Desktop/raspberry-pico/SDK/pico-sdk export PICO_EXTRAS_PATH=/mnt/c/Users/niuyuling/Desktop/raspberry-pico/SDK/pico-extras apt install cmake gcc-arm-none-eabi gcc g++ apt install gdb-multiarch automake autoconf build-essential texinfo libtool libftdi-dev libusb-1.0-0-dev # RP2040 SDK 版本构建 cd ~ git clone https://git.aixiao.me/aixiao/Danger-alarm.git cd Danger-alarm git submodule init git submodule update mkdir -p SOFTWARE/build cd SOFTWARE/build #cmake .. cmake -DPICO_BOARD=pico_w .. make # FreeRTOS 版本构建 cd ~/Danger-alarm/SOFTWARE-FreeRTOS mkdir build cmake -DPICO_BOARD=pico_w .. && make -j4 # 树莓派Zero W 433MHZ HC-12接收服务端构建(需要自己设置Raspberry Pi 串口) apt install libmysqlclient-dev cd ~ git clone https://github.com/WiringPi/WiringPi.git cd WiringPi ./build cd ~/Danger-alarm/SERVER/libconf && make clean; make cd ~/Danger-alarm/SERVER/hc-12 && make clean; make ./hc-12 ``` ## 展示 电路图: [ProProject_Danger-alarm_2024-03-21.epro](https://git.aixiao.me/aixiao/Danger-alarm/src/branch/main/HARDWARE/ProProject_Danger-alarm_2024-03-21.epro) ![brief](HARDWARE/IMG/SHC.png) 硬件: ![brief](HARDWARE/IMG/HW.jpg) 同步到Mysql: ![brief](HARDWARE/IMG/db.jpg) 433MHZ通信: ![brief](HARDWARE/IMG/display.png)
