Industrial Mains Power Monitoring and Alert System Over LAN Network

Abstract: To keep the server running properly, the temperature and humidity in the server room need to be considered because if the temperature or humidity in the server room is not suitable with standards it will disturb or damage the existing sever. For this reason, the condition of the server room must be monitored and the temperature andhumidity in the room are maintained. Also considering the mains power supply status, it is also important to read the status on mains power supply, the device will read the status and if mains power supply get down then device will switch on inverter power supply and send alert to user Email.

Keywords: Arduino UNO, ESP01 Wi Fi module, DHT11 Temperture and Humidity sensor, LCD16x2 , Ethernet.

1 Introduction

The proliferation of wireless devices has given risetotheinternetof things(IoT), whichallows systems to be linked and data to be shared between them. The capacityof IoTtobeusedforreal time monitoringisone ofthereasonsforitsrecentgrowthandpopularity.

ThisisthefoundationfortheproposedIoT based systemformonitoringspecificenvironmentalparameters such as temperature, humidity, air pollution, sunlight intensity, and rain, which has been found to be accurate andeffective.Traditionalmethods,whichtakelonger,cost more, and are often unreliable, are used to analyze temperature, humidity, air pollution, sunlight intensity, and rain. Furthermore, such regulation isn’t always possible to implement on a single platform. As mobile communication networks have reached remote areas, IoT based real time monitoring of environmental parameters such as temperature, humidity, air pollution, sunlight intensity, and rains has proved to be an efficient and cost effective solution. If the above mentioned environmental criteria are properly controlled using an integrated framework, it would have a wide range of application, including agriculture for observing healthy crop growth, industry for ensuring a clean working atmosphere, and city life for maintaining a healthy lifestyle.

The Internet of Things (IoT) has been increasingly emerging in order to build smart ecosystem, smart cyber realms, and smart apps. IoT and Big Data among other technologieswillperformamajorroleineducationbecause many learners have expectations to have personalized curriculum delivered to their desks. Pollution monitoring, waste management, water quality, protection, and other IoT based applications have been documented. The most affordablereal timemonitoringdeviceonthemarkettoday is very costly, and even if it is, it has poor features. Most devices are vendor specific, with extra payments for features such as alarm notices, reminders, and additional sensors.IoTisanenhancerofsystemeffectiveness,greater flexibility and further creation business opportunities and revenuestream.

2 Literature Survey

We collected literature study articles on Raspberry Pi and DHT11 sensors and we also collected research journals relating to temperature and humidity monitoring systems. Theinformationobtainedfromthisliterature study will be usedasareferenceinsystemdesign.

A. Design: In this process we will design our proposedworkindesigninghardware.

B. Assembly and Installation: In this part we have wireless LAN mesh network establishment and communicationwithcloud.

C. WirelessLAN meshnetwork establishment. The data will be shared wirelessly over the mesh network.

D. Communication with cloud: All gathered data willbe shared over the cloud and generate alert usingGmail.

E. Testing and Modification: Testing and modification will be done by using proteus software and logical hardware testing of prototype.

Transmitterdeviceisadevicewhichmonitormainspower supply and environmental status such as temperature and humidity. Whenever mains power is ON the device is workingon12vadapterpowersupplybutwhenpowercut OFF then device get switched on battery and ESPO1 sense the cut off then generate alert on wireless LAN network, Receiver device is a device which continue monitors the signal of transmitter device on wireless LAN network. Whenever we detect power cut off notifications then buzzerwillturnON.

3. Design Process

Block diagram

Figure1.OperationaldiagramofserverRoommonitor

a) Mains power monitoring : At input side just like showed in circuit diagram we added relay, at open terminal of relay input from mains power supplyisgivenandsamepowersupplyisgivento the coil of relay. Whenever mains power supply cuts off then relay trims to normally connected terminalandatthatterminalweaddedbatteryof 5V, this battery will work as UPS. At pin 2 the resistor is connected and that resistor is also connected to the mains power supply 5v adapter so if mains power cuts off then pin 2will goLow elsepin2willbehigh.

b) Temperatureandhumidity monitoring : Atpin 3 the DHT11 is connected. DHT11 is temperature and humidity sensor which transfer data over a singlewireprotocol.

c) ESPO1 : ESPO1 is a smallest WIFI module which allowus tocommunicateovertheinternet.Ithas 2GPIOpinsandoneserialport.

6] EthernetShield:

Ethernet shield provide a path to Arduino UNO to senddataovertheLANnetwork.Sothatthedevicewillget totally on network and communicate with other 3 devices andalsowithmailserver.

7] Buzzer:

Buzzer is just a sound making component used to makealertbybeeping.Inthisdevicetherearetwotypes of alert. Light and buzzer. There are 3 server rooms for each room there is respected bulb used for light indicator and a commonbuzzerforallserverroomsusedforsoundalert.

8] ChannelRelay:

DHT11:

Fig3.2 Recieverdeviceblockdiagram

DHT11 is a 3 pin sensor which senses the humidity and temperature in the environment. It is digital sensor uses capacitive humidity sensor and a thermistor to measure a surrounding air. Good for 20 80% humidity reading with 5% accuracy and good for reading 0 50°C temperaturereadings ±2°Caccuracy.
