落塵數(組裝)

PMS5003T (攀藤G5T) 是一款數字式通用顆粒物濃度傳感器，PMS5003T 可以用於獲得單位體積內空氣中懸浮顆粒物的質量和數量，並以數字接口形式輸出。

此Lcd 原為OLED 0.96" 修改成 Nokia5110 LCD，原始code沒有0.5um、1um等的顆粒數目，查找原始 data sheet，其實可以show 出來，花了點時間，讓他show 出來，即可，啊！啊！又第一名了，這樣LCD show 的才是無塵室 10萬級的顆粒數。



LCD影像說明:
T:溫度
H:濕度
pm1 , pm2.5 , pm10:單位ug/m^3
2.5u, 1.0u, 0.5u, 0.3u:單位，數目/粒徑
