Remote sensor Sensing with X-bee module.

on

Aruino board with Remote Sensing using X-bee module.

1.Project summary: - 

 In this project we gonna interface a temperature sensor and a simple digital switch sensor which  would be read by router X-Bee module and data of both sensor would be send in API mode to    coordinator.
 This project can be made with few simple steps. And picture of our project is shown below.

2. Components & software required:  -

In this project we are using X-bee module in the star connection.

Hardware components: -

          ·     Arduino board.
          ·     Three X-bee modules.
          ·     Two temperature sensor LM35.
          ·     Male to female jumper wires.
          ·     Male to male jumper wires.
          ·      Bread board.

3. Connections: -

In this project we are want to make a star connection of X-Bee module that can communication with each other. So a proper connections are really required to  make work of our project.

Do the connection for Router_1 and Router_2  same as show in the table two.



    4. Making of the project step by steps: To perform this project please follows the           following steps

Step 1: - Configuring all three of X-bee.

As we have learned how to configure the x-bee module in XCTU software in our previous project so configure the below X-bee module in below configurations.

 Co-ordinator:  - a coordinator is receiver node of star connection where ever X-Bee sends its                                         data.
      Set the parameter in below format.

  • Pan id: 1111.
  • Scan channel: 11.
  • Baud rate: 9600.
  • Parity bit: none.
  • Stop bit: one stop bit. And keep all the setting as it is.


Figure 5; co-ordinator configuration.


Router 1: - this X-bee takes analog data from temperature sensor and convert the analog data in                        digital form. And send data in API frame.
  •        PAN id: 1111.
  •        Scan channel: 11.
  •       JV (joint verification): enable.
  •       Destination address high:  0013A200 (Serial address high of Co-ordinator X-bee).    
  •       Destination Address low:  41241D89 (Serial address low of Co-ordinator X-bee).
  •       Node identifier:  Router 1 (Set your router name). 
  •       Baud rate:  9600
  •       Parity bit: None.
  •       Stop bit: one stop bit.
  •       AD1/DIO1 configuration: Digital input [3].
  •       AD2/DIO2 configuration: ADC [2].
  •       IR sampling rate: BB8 in HEX (3 sec or 3000 milli sec).


Figure 6: Router_1 configurations.


 Router_2: - Do the same configuration for third X-bee as Router_1 and name that one as Router_2.                 And just change the Sampling rate different so that information do not get collide at 
                      coordinator.


Figure 7: Router_2 configuration.



I made the sampling for Router_2 is 1388 (5000 milli second.). Now when all of three X-bees have been  configured thus we can start to play now.


Step_2: - Make all the connection and set the hardware as shown in the diagrams.



Figure 8: connections of all X-bee.


Make all the connection in the project as shown in the connection table and please be conscious, do not connect x-bee with high supply voltage, otherwise it may harm or module.

 Step_3: Now burn the Arduino with our code and open up the serial monitor to see the Value of                        Temperature and Digital switch on the serial monitor.

5. Result: - In our project two sensors are connected to the each of router X-bees, one is                     temperature sensor and other one is Digital switch. Those are being sampled at different                       sampling rate on each router X-bee module. And all the X-bee modules are connected in the star         connection and routers are communicating with coordinator X-bee.


      The result of this project can be seen on serial monitor of Arduino software.

6. Project specifications: -In this project we are configuring x-bee module for transmitting         a digital sensor data and a analog sensor data and reading this data on serial monitor of Arduino           software (IDE).

      ·    This project can be used on industrial and domestic level both. And can be place where we              want to monitor and data like temperature, humidity, moisture any kind of analog pr digital            sensor.
      ·    Range of x-bee in this project is around 30 meter and if we professionals X-bee module and          range could 1000 to 2000 meter also, which can be used to monitor sensor and                                communicating in many industries.   

 7. Arduino codes for this project: - Down load and upload this below code in you          coordinator side Arduino board.
