• [x] Dust Sensor approach with voltage division to adopt 5v out to 1v which is supported by esp8266
• [x] Make a 5v 1a power supply with parallel connection to the esp and dust sensor
• [x] Test dust sensor with 1v out and esp8266
• [x] Integrate dust sensor in the primary firmware

the first attempt attept - 1ce6656e369cc10850a0b708b28ae3dc5e786b42

1. 
2. 

results:

1. the first cycle of testing no real values (on esp32)
2. the next cycle of testing zero values (on esp8266, most probably damage on changing wires)

dust sensor mostly work

it should be connected to the esp so far it seems a voltage divider is needed

[chaos-adept]

physical assembly with wemos d1 was successful voltage divided by 1k*4 + 1k resistors

[chaos-adept]

added firmware and scheme which is used for ESP8266 NodeMCU v3

this ticket has been resolved dht11 is used instead of dht12 which is really hard to find in the Moscow shops, the new ticket for refactoring firmware will be raised
