# 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)
