Solar powered led light security

Solar powered led light security / Mohamad Zaki Ibrahim
Kuasa solar adalah satu pilihan tenaga lestari yang terbaik untuk keperluan pada masa hadapan. Pada masa kni, banyak teknologi telah dicipta berasaskan kuasa solar dan salah satu daripadanya adalah lampu LED solar keselamatan. Dalam projek ini, analisis prestasi lampu LED solar yang direka semula telah dikaji. Tenaga elektrik yang dihasilkan daripada fotovolta digunakan untuk menyalakan lampu LED dan mengaktifkan buzzer penggera. Lampu LED solar bekerja segerak dengan kehadiran bateri yang bertindak sebagai peranti penyimpanan tenaga. Dalam laporan ini, prestasi produk sedia ada lampu LED solar keselamatan telah dianalisis berpandukan kecerahan LED dan masa untuk pengecasan bateri. Ujian telah dijalankan berdasarkan beberapa factor yang memberi kesan kepada lampu LED keselamatan seperti jenis panel solar yang digunakan, jenis LED yang digunakan dan bateri. Projek lampu LED solar ini menggunakan papan Arduino sebagai salah satu komponennya. Peranti ini bertindak sebagai medium komunikasi dengan lampu LED, pengesan, dan buzzer penggera. Pertama, ujian telah dijalankan untuk menganalisis panel solar yang akan digunakan dalam projek sistem lampu LED solar keselamatan ini. Ujian ini telah dijalankan melalui berlainan kaedah iaitu tanpa beban dan juga dengan kehadiran beban. Berdasarkan keputusan yang diperolehi, panel solar memberikan kuasa maksimum iaitu 24.63W yang sesuai digunakan dalam projek ini dimana peranti ini hanya memerlukan sekitar 11W kuasa untuk ia beroperasi. Kemudian, ujian pengecasan dan nyahcas bateri telah dijalankan untuk menentukan masa yang diambil oleh bateri untuk pengecasan penuh dan nyahcas penuh. Berdasarkan ujian tersebut, ia mengambil masa sekitar 6.5jam untuk pengecsan penuh dan sekitar 8minit untuk nyahcas penuh. Pada masa sama, produk lampu LED solar sedia ada mengambil masa sekitar 6.167jam untuk pengecasan penuh dengan solar panel berkuasa 0.48W dipasang padanya. Walaupun projek lampu LED solar yang direka semula megambil sedikit masa untuk pengecasan penuh tetapi ia dapat menghasilkan keluaran tenaga yang besar. Eksperimen menganalisis lampu LED yang sesuai dgunakan telah dijalanakn berdasarkan kecerahan lampu LED. Projek lampu LED solar yang direka semul atelah memberikan kecerahan sehingga 960lumens berbanding produk lampu LED solar yang hanya memberikan kecerahan sekitar 100lumens. Berdasarkan keputusan yang diperoleh, projek lampu LED keselamatan yang direka semula memberikan lebih kecerahan berbanding produk lampu LED solar keselamatan sedia ada. Hal ini, ia amat sesuai untuk diletakan dekat halaman rumah. Dengan penambahbaikan pada sistem dengan kehadiran buzzer penggera, ia dapat menigkatkan rasa selamat pada pengguna. _______________________________________________________________________________________________________ Solar power is one of the best option for the sustainable energy requirement of the world. Nowadays, many technologies have been invented based on solar energy and one of them is solar LED light security. In this project, the performance analysis of redesigned solar LED light is investigated. The electricity produced by PV is used to light up LED light and to activate buzzer alarm. This solar LED light is worked synchronizing with presence of battery as a storage power device. In this report, the performance of the current solar LED light security is being analysed based on their brightness of LED and charging time of battery. The testing is conducted based on several factors that affect the performance of LED light security like type of solar panel use, type of LED light uses and battery. This solar LED light consists of Arduino board as one of its component. This device acts as a medium to communicate with LED light, sensor, and piezoelectric buzzer. Firstly, the testing is conducted to analysed the performance of solar panel for this solar LED light security system. Different method of testing that is no load condition and presence of load condition is used. Based on the result obtained, the solar panel gives maximum power of 24.63W that is suitable to use in this project since the input power desired of the device around 11W. Then, the charging and discharging of battery test is conducted to determine time required for fully charge and discharge of battery. Based on the experiment, it takes 6.5hours to fully charge and around 8minutes to fully discharge. Whereas the current solar LED light security takes 6.167 hours to fully charge with 0.48W solar panel attached to it. The redesigned solar LED light is able to give more power output although it takes a little bit time to fully charge of battery. The experiment to analysed the brightness of LED light is conducted to determine the best LED light that suitable to use. The redesigned solar LED light give a brightness of 960lumens while the current solar LED light give around 100lumens of brightness. Based on the result obtained, the redesigned solar LED light security give more brightness compared to current solar LED light. Thus, it is suitable to place at backyard of house. With addition of buzzer alarm to the device, it will increase a secure to consumer.
