This application: LM35 Thermometer 10 Background Bar Graph shows temperature values ​​in real time every 1 second through the most common temperature sensor, the LM35.

The scale reading is 0 ° C to 100 ° C (degrees Celsius) displayed on the screen Android Smartphone digital form ex: 25.7 ° C is also shown on the screen as Bar Graph;

Select the forward button until 10 Backgrounds with background images, making your application with a new look!

The presentation in the form of Bar Graph makes the app. More interesting showing the progression of the values ​​of
Temperature in the form of color bars, thus indicating the colors corresponding to the temperature value.

Monitor temperature remotely, remotely using your Android Smartphone! Very easy to assemble and use!

Ideal for monitoring room temperature, or at home in bedrooms rooms with fans or air conditioners connected; Monitor temperature greenhouses or cold cameras, etc;

Operation:
Mount the one with the Arduino JY-MCU Bluetooth and the LM35 temperature sensor as provided in the scheme blogger;

Connect the Smatphone Android and before starting the app first turn on Bluetooth;
If you start the app. with bluetooth off, a notification will appear, asking you to turn on Bluetooth, this time give Enter and turn on the Bluetooth Smatphone;

With the On and Smartphone Arduino connected make Bluetooth connection, please Smartphone and select Bluetooth and make the pair ordered default password settings comes with: "1234", enter the password and ready;

Now out of the settings between the application and press the Connect button to connect at this time the app. opens a list of available bluetooths, select your that is connected to the Arduino;
Ready will open the application screen showing the values ​​and local temperature, along with the presentation of the Bar Graph, view temperature with color bars.

Select the forward button until 10 Backgrounds with background images, making your application with a new look!

To exit the application press the Disconnect button to disconnect the bluetooths and close the app.

To re-enter will be very easy and convenient for your device is already set up and paired with your Bluetooth.

As the LM35 sensor works:

The LM35 is a precision sensor in Celsius and has an analog output voltage, its measurement range is from -55 ° C to +150 ° C with an accuracy of ± 0.5 ° C. The output voltage is 10mV / ° C. Its output can be connected directly to the port of any microcontroller.

LM35 is a basic operation for each output is 10mV in degree Celsius, then its output is measured at 222 mV, that is the temperature is 22.2 ° C.

When used 5V, the resulting resolution is 5000mV / 1024 = 4.8mV. As the LM35 has an output resolution of 10mV / ° C, the resolution is 10mV / 4.8mV ~ 0.5 ° C.
Based on these data we can build our Arduino code.
