How to Build Temperature Display on 16×2 LCD using LM 35 and Arduino UNO

ElcoHow. - There are many application that can develop using Arduino UNO microcontroller. One application Arduino UNO is to build temperature display using LM 35 and LCD 16 x 2 like in Figure 1 below.

In here we will give you one project on how to build Temperature Display on 16×2 LCD using LM 35 and Arduino UNO that like published by Circuitstoday site. Beside circuit schematic that appear here, you will redirect to original source to read more the listing program to produce the Arduino UNO work.

Electronic Circuit
Component List
  1. Arduino UNO
  2. LCD 16 x 2
  3. LM35 IC

Electronic circuit like in Figure 1 above is Temperature Display on 16×2 LCD using LM 35 and Arduino UNO circuit. According Circuitstoday site that published this circuit describe that LM35 is an analog, linear temperature sensor whose output voltage varies linearly with change in temperature. LM35 is three terminal linear temperature sensor from National semiconductors. It can measure temperature from-55 degree celsius to +150 degree celsius. The voltage output of the LM35 increases 10mV per degree Celsius rise in temperature. LM35 can be operated from a 5V supply and the stand by current is less than 60uA.

The +5v for LM35 can be taken from the +5v out pin of arduino uno. Also the ground pin of LM35 can be connected to GND pin of arduino uno. Connect Vout (the analog out of LM35) to any of the analog input pin of arduino uno. In this circuit diagram, we have connected Vout of LM35 to A1 of arduino.

Now lets go on to add a 16×2 LCD display with LM35 and Arduino – interface and lets display the temperature values on this LCD display (instead of serial monitor). So we are going to build none other than a stand alone temperature display using arduino.

To build Temperature Display on 16×2 LCD using LM 35 and Arduino UNO, you need some skill as follow:
  1. Basic soldering.
  2. Read a basic schematic.
  3. Assembling electronic component
  4. Design PCB layout
  5. Testing voltage and current
  6. Know LM35 Sensor
  7. Know Ardunio UNO Programming
Tools and Material

In this project, you must prepare some tools and material that used as the supporting to build Temperature Display on 16×2 LCD using LM 35 and Arduino UNO as follow:
  1. Tools: soldering iron, cutter, multitester, and Project Board.
  2. Material: Tin, PCB
  3. Software like Proteus 8, PCB Wizard

When you want to realize this Temperature Display on 16×2 LCD using LM 35 and Arduino UNO circuit into real application, you can build it as like design PCB layout using good software as like: PCB Wizard and to simulate and download this program to microcontroller you can use Proteus, AVR Studio 4, MIDE 51.
