1 Liquid Level Controller using ARDUINO Board andzigbee Module Sourin Acharjee Arunabho Kanti Som Arpita Ghosh Abstract: In this paper we have presented a remote liquid level controller using ARDUINO UNO Module. The level of the liquid is sensed, determined and transmitted and accordingly the pump can be controlled by a computer at a remote location. So far many works have been reported on the liquid level sensing but no work so far has been reported on the liquid level sensing and controlling from a remote location computer. The data related to the liquid level is transmitted to a computer situated in another location. The wireless transmission is done with the Zigbee module. The liquid level is sensed by simple BC547 transistor and several resistors and probes. The circuit diagram, hardware implementation and the output are also shown in this paper. Keywords: ARDUINO UNO, ZigBee Module, Liquid Level Detection I. Introduction In our day today life we need automation for reducing the time consumption.several automation in the traffic light control system[1-4], vehicle tracking system[5] has been reported so far. Sensing the water level of the tank [6-8] and automatically switching off the pump motor is a common scenario and example of automation. But for controlling the liquid level using a ZigBee module and ARDUINO board from a remote location has not been done.in this work we have used XBee module for wirelessly transmitting the data from the liquid storage to the control room, where anybody can see and control the pump without checking it physically. This device is cost-effective and low power consuming and thus suitable for medium level industries where power consumption is a concern. Also, installing a wireless module lessens the hackles of faulty wiring and abrasion faults of the wires. ATMega 328 microcontroller is used which ensures numerous options of future up gradation.here for the complete hardware implementation we have used BC547,LED, Probes, Zigbee (Xbee),ARDUINO Uno, 9V Battery and USB to UART Bridge Controller. For interfacing and programming the Zigbee modules, we have used the ARDUINO Uno board. We have used Xbee Series 2 Zigbee. This circuit has various advantages over the other circuits that are now functioning. The wireless transmission enables the user at some location to control the liquid level at remote locations. Due to high range of the Zigbee, a mesh network [9] can also be done so as to control a city or village. The simplest application of this circuit will be the control of overhead tanks in large apartments with several flats. In those circumstances, people face problems regarding switching of the pump. With the implementation of this circuit, which is easy to install, these people can make their pump automated in a very low cost. II.

2 Figure 1: circuit implementation of the work transmitter section and Receiver section Figure 1 shows the circuit implementation of the proposed work. Here we have connected the transistors and the LED s for indication purpose. Figure 1 shows the interfacing connections between the ARDUINO board and XBee. In our main liquid level detector circuit, we have used BC 547 as our sensor.we have connected and tested the circuit using a 9v battery. After connecting the circuit as the diagram, we have put all the probes from the bases of the transistors to the simple water tank that we have created. As shown in the diagram, we have put the probes in the levels accordingly. Now, after finishing the circuit design, we have test run it by filling up the tank. The LEDs light up showing the different levels. The receiver section is formed using a computer and a XBeemodule[10] shown in figure 1. The Xbee Series 2( XBee XB24-Z7WIT-004 module from Digi ) is used for wireless transmitter. The. Series 2 XBee improves on the power output, data protocol andit allows to create complex mesh based networks.these module allows a very reliable and simple communication between microcontrollers, computers. The first stage of the work is to interface the XBee module with the computer using the USB explorer.after accomplishing that next work is to connect the two XBee modules with each other for proper functioning. X-CTU software is used for necessary troubleshooting. The function digital write(pinno, STATE) is used to order the Arduino to switch the digital pin number (pinno) to a certain STATE (HIGH or LOW). The function pinmode(pinno, INPUT or OUTPUT) drives a certain pin number to take input or to give The function output Serial available()-checks if there is any signal available at the Rx and Tx of the ARDUINO. III. Flow Chart The flow chart shown in figure 2 gives the overview of the software implementation part,which has been implemented using the ARDUINO UNO board. The programming is done in C++ language. The different functions used for the program are discussed. Figure 2: Flow chart of the overall work 177 Sourin Acharjee, Arunabho Kanti Som, Arpita Ghosh

Figure 3,,(c),(d) shows the different liquid levels such as first level, second level, third level, forth level respectively detected by the ARDUINO board. The detection of the level is indicated using the (d) corresponding glowing LED. (e) Figure 2. Different level detections First level, Second level,(c) Third level, (d) Forth level and (e) Warning level The two XBee modules are configured using the XCTU software. The output for the different liquid levels are indicated using the LED at the vicinity of the circuit but the information of the levels are transmitted by the XBee module and it is received by a receiving XBee module fitted with the computer place in a remote location. The liquid level can be detected from the computer as well as the pump can be also controlled by the computer remotely. The computer screen at the output end is shown in figure 4. Figure 4, (c), (d), (e) and (f) shows the detection of 1 st level,2 nd level, 3 rd level, 4 th level and warning level respectively. (c) 178 Sourin Acharjee, Arunabho Kanti Som, Arpita Ghosh

5 Conclusion The complete work gives the detailed overview of the liquid level detector and controller implemented using ARDUINO Uno board and ZigBee module. It provides the user to control the pump operation according to the detected level displayed in his computer which is situated away from the location of the liquid tank. The complete work gives a low power consuming and low cost automation solution to the Liquid level control from a distance.
