Hardware

ESP8266 version ESP12 was used.

The prototype was based on the Witty board

REST         |       TXD
ADC    LDR   |       RXD
CH_PD        |       GPIO05
GPIO16       | BTN   GPIO04
GPIO14       |       GPIO00
GPIO12 RGB-G |       GPIO02
GPIO13 RGB-B | RGB-R GPIO15
VCC          |       GND
            USB

The following pins are used:

  • GPIO4 PM1006 particle sensor
  • GPIO2 WS2812 stripe out of three LEDs, replacing the orignal LEDs at front
