Membuat Automatic Bathroom Lamp (ABL)

Tanggal : 09/01/2015, dibaca 2832 kali.
Listrik merupakan kebutuhan masyarakat saat ini, setiap orang membutuhkan energi listrik untuk memenuhi kebutuhan sehari-hari. Salah satunya adalah untuk penerangan atau lampu di dalam rumah. Dalam rangka menghemat listrik, maka matikan lampu setelah digunakan.

Dalam penggunaan listrik kita harus berhati-hati dalam mengoperasikannya, jika tidak, maka akan menyebabkan kecelakaan. Terutama jika ini terjadi karena kurang tahuan, terutama pada anak-anak kecil. Misalnya ketika seorang anak yang umurnya dibawah 7 tahun, masih sangat butuh pengawasan orang tua dalam menyalakan dan mematikan saklar lampu, terutama jika kondisi tangan basah, misalnya setelah keluar dari kamar mandi dan akan mematikan lampu kamar mandi, ini akan sangat berbahaya.

Adakah alat yang secara otomatis yang akan menyalakan lampu ketika seseorang memasuki ruangan, dan lampu akan mati sendiri ketika seseorang sudah keluar dari ruangan ?
Dari pertanyaan diatas, maka munculah ide dari penulis untuk membuat alat “Automatic Bathroom Lamp (ABL)”, dimana alat ini dapat digunakan untuk menyalakan dan mematikan Lampu Kamar Mandi secara otomatis, alat ini akan sangat bermanfaat terutama jika dirumah tersebut memiliki anak kecil, yang tentunya sangat rawan jika menggunakan saklar lampu, selain tinggi badan masih kurang juga pengertian dan pemahaman tentang bahaya listrik masih sangat kurang, apalagi ketika keluar dari kamar mandi kondisi tangan masih basah.
Spesifikasi Teknis Alat
Dimensi : 7 x 11 x 5 cmm
Tegangan input : 12 V DC
Tegangan Output : 110-220 V (sesuai pemasangan & kebutuhan)
Konsumsi Daya : 0,5 W
Arus max : 10 A (Optional sesuai Relay yang dipakai)
Daya jangkauan : 1-3 meter
Proses dan Cara Kerja Alat Automatic Bathroom Lamp (ABL)
Cara kerja alat ini adalah dengan menggunakan sensor gerak atau sering di sebut dengan PIR (Pasive Infra Red). PIR akan menghasilkan tegangan 3 V jika mendeteksi gerakan, tegangan 3 V inilah yang akan dikuatkan untuk menggerakkan Relay yang akan mengontrol nyala lampu.

Design Rangkaian ABL

Alur Kerja ABL
Alat ini sangat bermanfaat ketika dipasang di kamar mandi, dimana sensor gerak akan mendeteksi manusia yang masuk ke kemar mandi, dan secara otomatis akan menyalakan lampu.
Ini sangat bermanfaat untuk penghematan energi listrik, karena kita sering lupa untuk mematikan lampu ketika keluar kamar mandi.
Anak kecil tidak perlu meminta orang tua untuk menyalakan lampu kamar mandi ketika akan masuk ke kamar mandi.
Menghindari bahaya sengatan listrik, karena kondisi tangan yang basah ketika meninggalkan kamar mandi, dan harus mematikan saklar lampu.
Dapat digunakan sebagai alarm untuk menghindari pencurian, jika sensor ini dihubungkan dengan bel atau alarm atau buzzer.
ABL Siap dipasarkan/dijual

PCB ABL siap dirakit
ABL meraih Juara 2 Krenova 2014 Kabupaten Sragen
(buka dengan aplikasi PCB Wizard untuk membukanya)

Eliminate alcohol, espresso, cigarettes, refined sugars, and fats, which act as toxins in the body and are hurdles to your healing process. Beljanski recommends detoxification as a all natural <a href=>essential oils for aging</a> way to keep your mind and body healthy, though it's a broad term and can connect with many types of health ideas. Or if you're on the run, decide instead for an easy digesting gut healthy smoothie.
A good menu follows that has natural and healthy things that will promote digestion, introduce fiber, and help you to perform a cleanse in a regular and natural way. Do not execute a body cleanse specifically for weight damage, you is only going <a href=>cardio before sleep</a> to lose water weight which you will regain again once you begin eating quite normally again. This helps one to naturally detox the body and eliminate the things that may have been making you unwell.
Rather than turning to a premade concoction or chemically increased smoothie, just utilize natural foods that will get you cleansed properly. By focusing only on your breathing, you are clearing and cleaning the mind <a href=>fat burner review</a> which, subsequently, has an optimistic effect on the body. When you select the right organic foods then you prevent the toxins that may be harmful to your health.
The takeaway here is to rev your heart rate, break a sweat, and get in a better mindset to kick it up a notch again tomorrow. We also consulted award-winning nutritionist and spokesperson for the Academy of Nutrition and Dietetics Heather Mangieri how healthy the common <a href=>peanut butter protein shake weight loss</a> detoxification fix is and ways to effortlessly detox over time. Another way to do a skin cleansing at home is more prevalent than you think: exfoliating to keep the skin healthy and free from dead skin skin cells.
But as as it happens, there's a lot more to seriously detoxing than simply the trendy juice cleanse, and some methods are healthier than others. Once again, this cleanse has not be scientifically proven to effectively remove toxins. Detoxing is great for the body. Exercising can help you sweating, and sweating helps release poisons through your <a href=></a> skin. When performing a little cleanse, the advice I share with clients is to skip the bakery, cereal or any version of these at breakfast time as they'll cause your system to keep more drinking water, and instead focus your attention on protein, that will provide satiety.

It's the first time we have used the on-line service and it was great too.

These set ups are suitable for either indoors or outdoor set-up, and that means you have a great deal of options as you plan your child's play space.
Problems Viewing
Perfect for thoughts and participating in hide-away. Features are likeable enough with different choices of elegance and style that means it is exciting to have your pick.

Sign up to get special deals, free giveaways, and once-in-a-lifetime discounts. The product didn't disappoint, it's an extremely nice heavy canvas and it is bigger than it looks online. You cannot get a refund if you have positioned a ShippingPass-eligible order. The teepee itself was easy to put together <a href=>play teepee</a> and really adorable looking, but the customer we purchased it for couldn't stand the odor of the textile. I ordered 6 different teepees for a camping themed sleepover party.
Kids love cosy spaces, especially if they're hidden away from the rest of the house. My personal inclination is to buy a more substantial teepee that can support either yourself (to learn stories to your kids) or multiple children at once. Make it extra special with personalisation available <a href=>play tent</a> on quite a few play tents. I am a solid believer of experiential play more than technology established fun for kids as I see it as the natural way to draw out a whole lot of skills and development at an extremely young age.
