  *** MAKING A MODULAR SYSTEM FOR D.I.Y. GROWBOX / GREENHOUSE   
   
   
   
     
  ***Independent Grow Box Controller that can be used to Control all the Important devices to maintain   
  *  
  *  
  the ""Grow Environment"" for example Lights, Heater,Cooler,Fan for blowing air inside the box ,Fan for exhaust,   
  Humidifier or mist maker,Water pump ,Solenoids etc   
     
    
      
  *****i WILL improve it as i learn more :)

  //**********************//**********************//**********************   
     
  1.Arduino Nano   
     
  2.A thermistor (i used A 10K WATERPROOF ONE)   
     
  3.A resistor (matching the value of the thermistor's "nominal resistance at 25 DEGREES C" for example: 5k resistor for 5k thermistor)   
     
  4.SPI OLED display ssd1306 (mine is ssd1306 but got it working by using sh1106 constructor also got rid of the "white line problem")   
     
  5. DHT 22 (WITH PULL UP RESISTOR I USED 10k OHM)  
     
  6.RELAY MODULE LOW LEVEL TRIGGER TYPE (6 Relays required in total for all the pins, can be separate 4 CAN WORK TOO )   
     
  7. DS3231 RTC MODULE (RESISTOR from charging circuit REMOVED and charging DISABLED..BECAUSE I USED CR2032(NON-rechargeable)Cell   
     
  8. AN LED WITH APPROPRIATE RESISTOR FOR USE AS A STATUS LED   
     
  9. Soil Humidity Sensor   
   
  10. Water Level Sensor  
   
  11. Two Stable 5 Volts DC Power Sources with Separate Grounds For Complete Optical Isolation (one can work)
