Women Safety Device with GPS Tracking using Arduino

In today’s world women safety has become a major issue as they cannot step out of their house at any given time due to fear of physical abuse and violence. Now these can be brought to an end with the help of a women safety device. This safety device consists of a micro controller, emergency button switch. On sensing the emergency situation this device provides the current location of women and sense it to emergency contact through GSM MODULE. This safety device also includes a LED and an electric shock inverter circuit which is used to hurt the attacking person due to which there is a chance for the women to escape. GPS receiver gets location INFORMATION from satellite in the form of latitude and longitude. The GSM modem sends an SMS to the pre-defined mobile number. When a woman is in danger she can press the switch which is with her. By pressing the switch the entire system will be activated. Then immediately the SMS will be sent to the person with location using GSM and GPS which can be traced from the goggle maps.

Pengembangan aplikasi raspberry pi sebagai mesin survei kepuasan pelanggan

This customer satisfaction survey machine was created to facilitate the survey process that will be used in the framework of the feedback process. This feedback is used as an evaluation material to continuously improve servants. This machine is made of Raspberry Pi as a mini personal computer (PC), which is equipped with a push button switch button as a survey input, as well as a 32 inch TV screen as a display. The programming language used is python, with Graphic User Interface (GUI) using Tkinter programming. From the survey engine, it can be seen a report on the number of respondents taking the survey. In addition, this tool can record survey data and present it in graphical form as a report.

RANCANG BANGUN SISTEM ANTI NGANTUK PADA PENGENDARA BERBASIS ARDUINO NANO

Kecelakaan lalu-lintas adalah kejadian dimana sebuah kendaraan tabrakan dengan benda lain yang menyebabkan kerusakan. Kadang kecelakaan ini dapat mengakibatkan luka-luka bahkan kematian manusia atau binatang, Salah satu faktor penyebab kecelakaan adalah mengantuk. Penelitianinibertujuan: (1) Merancang bangun sebuah sistem anti mengantuk pada pengendara berbasis arduino nano. (2) Membuat rancang bangun sistem anti ngantuk pada pengendara berbasis arduino nano. (3) Mengimplementasikan alat sistem anti tidur kepada pengendara. Penelitian ini dilakukan pada bulan Juli sampai dengan bulan Agustus 2018 yang berlokasi di Jalan. Paropo2, Workshop STMIK Handayani Makassar, dan bebrapa ruas jalan di kota makassar. Pada umumnya dalam berkendara, Salah satu penyebab kecelakaan lalulintas adalah disebabkan karena mengantuk . Maka untuk mengatasi Permasalahan demikian dilakukan penelitian dengan membuat sebuah sistem anti mengantuk untuk pengendara. Sistem demikian dirancang menggunakan arduino nano sebagai kontroller dan sensor detak jantung XD-58C yang berfungsi untuk mendeteksi Detak jantung Pengendara ketika sedang terjaga dan sedan tertidur ketika berkendara. Arduino nano menjadi pusat data untuk mengkondisikan kerja alat yang lain yang akan saling melengkapi dalam fungsi masing-masing. Dalam hal ini juga kami menggunakan motor servo sebagai alat kejut untuk pengedara ketika mengantuk dan button switch sebagai tombol untuk memilih menu pada alat ini. Sistem ini juga dibangun menggunakan bahasa pemrograman C++

Implementation of a wireless charging system for mobile devices

This work describes the implementation of an RF based wireless charging system using RF transmitting and receiving modules. The objective of this work is to implement a system that has the ability to interact and communicate wirelessly within short range. This mobile wireless charging switching system consists of two sections, the transmitting and the receiving section. Each section was interfaced to 433MHz transmitting and receiving modules. The transmitter section of the wireless mobile charging system sends bursts of 433MHz signal through push button switch which is used in the initiation of the charging process to the receiver; when this signal is received by the receiver, it activates a relay which in turn switches on the internal power that comprises the backup battery, DC-to DC converter via a Universal Serial Bus (USB) port to the mobile device to begin charging. This work was able to achieve a wireless transfer of power for distance of about one metre between the transmitter and the receiver.Keywords: wireless charging, radio frequency radiation, electromagnetic induction, inductive coupling, microcontroller,

The Design of Intelligent Responder Based on SCM
