Remote Monitoring System with Labview and XBee



Remote Monitoring System with Labview and XBee: Remote monitoring system with labview and xbee is a system that could be used for remote monitoring of temperature, humidity and intensity of light. In this modern world, there are so many places where we must have to control or monitor the temperature, humidity and intensity of light such as in hospitals, educational institute and semiconductor devices making industries where the humidity is strictly prohibited. In these places, if we install the separate system for monitoring of each factor such as temperature, humidity or intensity of light, then this could be so much expensive, and not easy to install everywhere. For resolving these issues, we have designed a system that is called a remote monitoring system with labview and xbee with the help of Arduino board, DTH11 sensor, LDR sensor, LCD display and xbee module. With the help of this system, the temperature, humidity and intensity of light could be remotely monitor through a single printed circuit board(PCB).

 Components List of Remote Monitoring System with Labview and XBee

This remote monitoring system with labview and XBee has following components list with detail,

Transformer: In this remote monitoring system with labview and xbee, transformer is used for step down the 220V ac into 12V ac for directly connected this system with wapda bus bar. It consists of two windings and work on the principle of mutual induction.

Bridge Rectifier: In this remote monitoring system with labview and xbee, bridge rectifier is used for converting the ac voltages into dc voltages and connected at the output of transformer.

Blocking Diode: In this system, the blocking diode is used for saving this system from reverse current in other words it blocks the reverse polarity current.

Voltage Regulator: In this remote monitoring system with labview and xbee, voltage regulator is used for regulating the 12V dc into 5V dc for supplying power to microcontroller and LCD display. It is connected at the output of bridge rectifier.

LCD Display: In this remote monitoring system with labview and xbee, the LCD display is used for displaying the temperature, humidity and intensity of light. It is interfaced with microcontroller and is powered up with 5V dc.

DHT11 Sensor: In this remote monitoring system with labview and xbee, the DHT11 sensor is used to detect the temperature and humidity. It is a digital temperature and humidity sensor, which uses the capacitive humidity sensor for measuring the humidity and thermistor for measuring the vicinity temperature. It is low cost, low voltage and low current sensor. It is powered up with 3V dc to 5V dc and consume low current only 2.5mA during conversation.

LDR Sensor: LDR stands for light dependent resistor which consists of high resistance almost 5000 ohms in day light and 20000000 ohms in dark light, this resistance is decreased with the intensity of light, means its resistance is inversely proportional to the intensity of light. In this system, it is used for measuring the intensity of light. It also a low power consuming sensor.

Arduino Board: In this remote monitoring system with labview and xbee, the Arduino board is used for intelligent control of this system. It is interfaced with DHT11 sensor, LDR sensor, xbee and LCD display. It is a 14 pins controller board, powered up with 5V dc and programmed in c language with the help of Arduino IDE software.

XBee Module: In this remote monitoring system with labview and xbee, the xbee module is used for wirelessly communication between each other, means the two xbee module can easily communicate with each other by using simple serial communication wires. In this system, two xbee modules are used one is interfaced with microcontroller for sending or receiving data from microcontroller and on one for sending or receiving the data from user computer or website.

Labview: In this remote monitoring system with labview and xbee, labview software is used for the graphical representation of receiving or sending data. It consists of front panel for user interface and block diagram for programmable logic.

Working Principle of Remote Monitoring System with Labview and XBee

This remote monitoring system with labveiw and xbee works of the principle of LDR and DHT11 sensors working. These sensors sense the temperature, humidity, intensity of light, then convert this analogue data into logic data and send this data towards Arduino board. The Arduino board is used in USB to TTL converter mode. In this mode, it gets the data from sensors and then analyze this data with respect to program data then send this data to xbee module. In this system two xbee modules are used which are interfaced with each other through wireless network, xbee 1 module received the data from Arduino board and then sends this data to xbee 2 module through the wireless network. The xbee 2 module is interfaced with user or consumer computer through the USB cable. Similarly, the user can see this data to his computer with the help of labview software, which have graphical and logic form of this data. The user can also see this data at his dedicated website. So, this is the very easy and simple way for monitor the remote data of consumer or user.data on labview
