Iot Control Of High Voltage
Introduction
Introduction to IOT: Everything in today’s world is with Internet. Internet is an interconnection of computers all over the globe. Internet connects billion of devices worldwide, which allows for the exchange data all over the world. Internet has tremendous utilizations and applications in numerous fields and space. One of the critical utilizations of the internet is IOT. The Internet of Things (IOT) is one of the far-reaching and promising technological talking-point today and it became a part of the modern world. Significance and utilization of IOT is more than thirty billion connected devices and counting. Around us, there are wearables, smartphones and other devices, all of which use sensors. IOT is interconnection of physical items and electrical amounts like Voltage, Current, Power, Power Factor, Energy, and Frequency in electrical power framework has a tendency to vary, because of load changes, unsettling influences, or other anomalous states.
The change-state in electrical amounts ought to be distinguish quickly, else it can prompt major issue for entire framework. Subsequently a need is required to decide the state of power change-state rapidly and properly with a specific end goal to settle on viable choices [1]. Many control problems which were previously solved using mechanical or electrical switching systems, can now be solved more effectively and reliably using electronic devices. The heart of such an electronic monitoring and control system is a microprocessor. This increased use of microprocessors in monitoring and control problems has led to the appearance of microprocessors which are designed for the sole purpose of monitoring and control. These types of microprocessors are referred to as microcontrollers which control numerous products and devices, such as automobile engine control systems, medical devices, remote controls and it will continuously monitor the different parameters like Output voltage, Output current and Temperature of the circuit. It contains one or more processors along with programmable input/output and memory. In this Arduino board is used to help the microcontroller easily.
To speed up the processor Raspberry Pi is used it is single board computer which contains ROM (Read Only Memory), SOC (System on Chip). System is designed by integration of WSN’s with internet and Ethernet to acknowledge the power management and provide information services using IOT platforms [3]. Wireless sensor networks is based on the concept of gathering energy information about physical phenomena in different applications such as habitat monitoring, observation and operating with different communication standards. The WSN’s are used in the home for energy controlling services. Home appliances are controlled and observed by placing WSN’s in the house. Sensor mechanism is crucial for identifying various kind of industrial WSN in IoT environments and it allow us to obtain sensor data. New technologies includes advancements in Information technology, distribution, transmission and electricity shortage technology as well electricity is basic for daily life and to spine for the business. Now a days it’s very big problem to maintain health flow of energy, load has to be taken control. If the control of the load is restricted over a small area does not give the required efficiency. The solution for this opting cloud computing. The system uses brilliant detecting unit that identifies and controls the home apparatuses.
Design and implementation of WSN’s
Sensor modules are placed to the load for measuring voltage parameters of the load. The details of design and development of the sensor modules are provided in the following sections. In comparison to different traditional techniques WSN is low-cost, easy to convey and low power consuming. To get the solutions for different complex problems of data transferring and storage WSN is broadly used in IOT. Micro controller is used as core unit in main stream data acquisition. Various users have their own applications which require different sensors. Writing code for the complex problems which brings many challenges to the researchers. To transit the electrical parameters to cloud through Internet USB dongle used connected to raspberry pi.
HARDWARE
RASPBERRY PI Raspberry pi is a fully featured small computer which is ability to run multiple applications just like a regular personal desktop developed by raspberry foundation in UK. The goal was to build a minimum cost device that would give better results in hardware and software programming. It was designed for Linux operating system but recommended is Raspbian. Foundation which provides multiple operating systems like Snappy, Ubuntu, Noobs. Pi which acts as main control and it is superior of Arduino. It also support various programming languages like Python, C, Perl and Ruby. This device completely build on Broadcom BCM2835 SoC which hold a 700 MHz ARM1176JZFS CPU with hardware floating point unit. The specifications of raspberry is 512MB to 1GB random access memory and an SD card for memory storage.
ARDUINO UNO
Arduino Uno is open source electronics platform and a microcontroller based board based on AT mega328 and the chip is programmed to do different tasks and transmit the information from computer to microcontroller and then finally send to particular circuit. [5] Using Arduino we can the access the information from sensors, antenna and also sends information to output devices like LED, speaker, LCD and direct current motor.
Current Sensor
Current sensor is to monitor voltage and alternate (AC) or direct (DC) current. To measure the voltage or electricity, current we are using current sensor which gives accurate voltage. Hall Effect IC’s which provide high accurate and low noise output voltage signals that are proportional to an applied AC or DC current. To measure the voltage we are using ACS712 sensor. For example, by applying 5v and passed to Vcc of ACS712 breakout board and GND must be negative of 0v of supply once the electricity is passed current generates through sensing pads and provide the output voltage. When the load is OFF the sensor generates Vcc/2 which is no load voltage. We can calculate the current in both directions using sensor. To sum up, if the voltage is greater than 2. 5V it shows in one direction, similarly if the voltage is less than 2. 5V it indicates the other direction.
Voltage Notice Circuit
A voltage sensor circuit is a circuit that can sense the voltage input into it. AC voltage that we can give to transformer is from 50V to 230V depending on its ratings. Rectified DC is fed to the voltage divider circuit. By seeing the circuit connect Arduino and make ground common to get the genuine reading balance the resistor R1.
Conclusion
This paper describes how to control and monitor high voltages and voltage drop in the equipment or circuit and the techniques used to handle the challenges. By using wireless sensor network, system controls the power consumption of house appliances remotely to avoid high voltage in the circuit. Android application which leads major role to continuously view the appliances.
