# leaves drying with temperature control (DHT22 & relay)

   Controlling heat generated(heat is generated by  100W bulbs) to dry leaves.

   Tempeature reading of the sorrounding  taken by DHT sensor,.

   The whole control is achieved by on-off mechanism of the relay(turn on/off the bulbs)

   temperature readings and status are then updated on the LCD(I2C LCD)

   Buzzer and LEDs are used to give quick notification on the status

   

   **Note: i2c pins on arduino uno and nano are**

   

   sck---> A5

   

   dt----> A4

   Using built-in I2C scanner example *(File->Examples->Wire->i2c scanner)*,

   scan its I2C address(this address is used when creating an instance of LiquidCrystal_I2C)

**The components  used**

 - Arduino Nano

 - DHT22( temperature sensor)

 - Relay

 - LCD(I2C)

 - LEDs
