This paper aims to design a digital overcurrent relay with a characteristic of a standard inverse that can comply to the IEC standard 60255. The overcurrent relay which is used to protect one phase of an alternating circuit (AC) from the overcurrent disturbances consists of an arduinouno as a microcontroller to control the operation of the relay, a current sensor ACS712 with the allowable current up to 30A used to detect the input current to the relay and a circuit breaker module. The Time Multiplier Setting (TMS) of the relay was set at 0.1. The trip test of the relay was conducted at a varying TMS from 0.1 to 0.4 and the operation current was limited to 1A. When a fault current was detected at 2.02A, it was found that the operation time of the relay occurred at 1008ms with a TMS of 0.1 and at 3932ms with the TMS of 0.4. Increasing the fault current to 3.99A decreases the operation time to 504ms at the TMS of 0.1 and to 2016ms at TMS of 0.4. From these findings, it can be concluded that the prototype of the digital overcurrent relay can fulfill the inverse characteristic of the standard IEC 60255.

Liquefied Petroleum Gas (LPG) is highly inflammable and can burn even at some distance from the source of leakage. One of the preventive actions to avoid the danger associated with gas leakage is to install a gas leakage detector at suitable locations. The purpose of this paper is to execute the simulation environment of the LPG leakage detection system. This system consists of an arduino uno microcontroller, LPG leakage sensor MQ-2 and ESP8266 Wi-Fi Module. The Wi-Fi module will send the warning message notification through a user's smartphone with the help of Blynk application interfacing software. The simulation system is successfully detecting the LPG leakage and can alert users within a short time.

Modern agriculture system involves an automation technology (AT) which supports formers to do their activities at maximum extent. This paper proposes a wireless smart automation (WSA) influencing IoT system that supports mobile user interface for real time crop field monitoring and controlling. It reduces effect of manual interpretation for agriculture farming and field monitoring. It deploys a dedicated global server for user control accessibility anywhere around the world. Thereby, the drones are operated from smart mobile which have unique IP connectivity for secure authentication arduino uno microcontroller. The major advantage of the proposed system allows continuous crop field monitoring and ensures limited usage of pesticides and fertilisers. Additionally, user can monitor their farm field by using unified Android mobile app and thus, ensure delay difference between turn ON and OFF state by 2 seconds irrespective of any load conditions at any time.

Agriculture is one of the most traditional methods practiced on earth. Appropriate conditions and suitable moisture are essential for crop production. In this research, an intelligent irrigation control system is deployed using an adapted Internet of Things (IoT) platform to monitor agri-cultural fields efficiently and effectively utilizing water resources. Different parameters, such as soil moisture, humidity, temperature, and rainfall, are sensed using sensors placed in the agri-cultural field where the crop is grown. Sensed data is stored in a cloud framework. The motor pump can be toggled between the ON/OFF states manually from a remote location using the mobile application. Additionally, if the system is switched to automatic, it estimates the threshold soil moisture value and irrigates the fields when the soil moisture is low. The proposed system monitors and automates the irrigation process, and it uses the IoT and cloud platform to enable data acquisition.

In this paper, we present the synchronization of a chaotic system using a discrete-time recurrent high order neural network. This is done by using a Genesio & Tesi oscillator circuit in discrete-time embedded into an arduinomicrocontroller that provides the state space variables. A discrete-time recurrent neural network is designed to synchronize the dynamics of the chaotic oscillator. This neural network is trained using a time-varying training algorithm where it is used the Extended Kalman Filter. Two state space variables are captured in real-time in ADC inputs of a compact development system, where these signals are synchronized by the recurrent high order neural network in discrete-time. The proposed work allows synchronization of interactions associated between the neural convergence and the chaotical plant state. The obtained real-time results, and the statistical analyses on the synchronization process validate the possible application in chaos-based communications systems. (C) 2019 Elsevier Ltd.

Technical upgradation in the field of surveillance as well as in remote package delivering systems have led us to the development of a quadcopter. The quadcopter's flight controller is developed using arduinouno R3 based microcontroller board and its flight movements can be controlled using a transmitter-receiver setup. A gyro cum accelerometer module is attached to give the exact coordinate location of the place where the quadcopter is positioned whereas the magnetometer module indicates the direction of travel. The microcontroller is supplied with a LIPO battery. The microcontrollers are programmed to turn on the quad rotors using electronic speed controllers (ESCs).

This paper presents a prototype which can locate the area of highest sun intensity and track it according to its movement. The device used to track the sun uses a light dependent resistor connected to two stepper motors, used to generate movement of the panel on both vertical and horizontal axis. The motors, connected to their drivers, together with the light dependent resistor and a potentiometer, are connected to the arduino uno microcontroller. The purpose of the prototype is to improve the solar panels to generate up to 60% more energy by enabling solar tracking and by ensuring the panels maintain a perpendicular angle to the sun rays. The solar tracking functions compare a defined maximum value with the data coming from the light dependent resistor and find the difference between the two values, then chooses the smallest value, which correlates to the highest sun intensity.
