Picture of Solar Hot Water Controller With Arduino Mega and Ds18b20 Temp Sensor

This is project for control solar system.

Step 1: Things U Need

Picture of Things U Need

Parts:

  1. 1xArdunio
  2. 1xLCD 16x2
  3. 3x4.7 kOhm resistor
  4. 2xN-P-N transistor
  5. 2x5v relay
  6. 3xDS18b20 temperature sensor
  7. 1xBreadboard
  8. 2x220 Ohm resistor

Step 2: Connecting DS18b20 Sensors

Note: 4.7kOhm resistors don't change to any nominal.

Step 3: Connect LCD

In program I connect the lcd keypad and I suggest connect lcd wires as keypad

Step 4: Uploading Programm

All libraries is in arduino only OneWire not in arduino you can download this fom here.
