2019 ESP8266 PM7003 PM2.5空氣清淨機

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

飛利浦空氣清淨機-AC5659濾網芯組合2片HEPA-活性碳

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， forum <<< 按一下

void setup() {  
/* following for led */
pixels.begin(); // INITIALIZE NeoPixel strip object (REQUIRED)
}

loop() {

pixels.clear(); // Set all pixel colors to 'off'

  for(int i=0; i<NUMPIXELS; i++) { // For each pixel...

    // pixels.Color() takes RGB values, from 0,0,0 up to 255,255,255

    // Here we're using a moderately bright green color:

    pixels.setPixelColor(i, pixels.Color(0, 150, 0));

    pixels.show();   // Send the updated pixel colors to the hardware.

    // delay(DELAYVAL); // Pause before next pass through loop
