2019 ESP8266 PM7003 PM2.5空氣清淨機
已試用半年, 感覺得很滿意!
這濾網好像不錯
外接AC110V 正負離子殺菌及剩餘負離子除灰塵
2020 Jan 第二版 更改如下
GPIO 14 (D5) 空氣濾芯PWM風扇 , 採用COOL MASTER JETFLO 120(95CFM 12X12X2.5CM 12V 0.4A 4.8W 36dBA)
GPIO 12 (D6) USB臭氧空氣清淨機 (可Micro USB to FUTURE LAB N6 , PM2.5 >=15啟動),
GPIO 13 (D7) USB加濕器 <<<-----改為GPIO15 (D8) USB加濕器, 濕度低於50%啟動加濕,
達到55% 停止加濕.
(GPIO 13 給 SPI OLED SSD1331使用, 2020彩色OLED用不到)
GPIO 13 (D7) 2020 LED (CJMCU-2812-24)
GPIO 16 (D0) Latch Relay ON,
室內溫度超過26度 另外啟動交流電風扇 (LATCH RELAY導通)
GPIO 0 (D3) Latch Relay Reset (OFF)
室內溫度低於25度 關閉交流電風扇 (LATCH RELAY 斷線)
- GND - 0V, VCC - 3.3 to 5V,
- SCL - GPIO13, SDA - GPIO 9, DC - GPIO8, CS - GPIO 10

Dht22 濕度真不佳，買十個一個比較準。
這裡也有人講是垃圾，
