ab版tvoc传感器对比sgp30传感器数据失真 #8
Comments
我也是这样的 |
通风都降低到最低,sgp30传感器需要温湿度校准,以及单位系数 |
esphome自带的sgp库输出是ppb,需要换算成质量系数需要系数,在手册Total Volatile Organic Compounds (TVOC) and Indoor Air Quality (IAQ)里面有这么一段The mean molar mass of this mixture is 110 g/mol and hence, 1 ppb TVOC corresponds to 4.5 μg/m3. |
求个配置~~ |
大佬写的文件里有个倍数设置。 |
