- PCB Redesign;

- Change from ESP8266-01 to ESP82266-12F;

- Add 2 new sensors (temperature, humidity and gas); I accept suggestion for sensors (sensor Mq-2 and Dht11)

- Add 3 Push Button Switch 3*6*2.5mm smt Tactile switches 3*6 smd tact switch ( 1 mode setup / 1 (+) / 1 (-) )

- Update BOM componets with end of life;

- Work on tentative the remain within PCB same size.

- Ultimate goal is to make the PCB with the lowest possible cost of production and manufacture 10 samples for test;

notice: currently i am using MCU Mega 2560 and isn't possible deploy FOTA (firmware over the air) with ESP8266-01 (Serial3). So, if identified any concerns please, let me know before start
