The Entry Denial Device or EDD for short, is a security device targeted towards those individuals who live alone in dorms or flats that are incapable of making use of conventional security systems such as a CCTV or alarm due to certain circumstances. Tenants who rely on cameras owned by the landlords may not be able to take proactive measures to protect their accommodation as they can only access footage in case of an incident. The device will be used to alert owners from intruders having unauthorised access to other property. Furthermore, it is a deterrent to keep thieves at bay as well as being very discreet due to its size. Another feature is that the device can be placed in areas that are hidden from view. This mobile device can be relocated and installed in different places. The device is also simple to use and easy to set up for people who cannot afford advanced systems or have little to no knowledge (boomers) on how to use or install a more advanced system. It triggers an alarm when the laser is broken alerting the owner who is then able to take necessary action of safeguarding. This mobile device can also be relocated and installed at different places. The Entry Denial Device can also trip a silent alarm and send a text message to the owner’s phone instead of the standard alarm.
Global Challenge 12: Responsible Consumption and Production
The materials we use include a LED pointer light, raspberry pi, capacitors and light dependant resistors. Most of these materials are biodegradable and reusable as the resources have a long-life span so they are not replaced often, saving costs on production and transportation, therefore cutting down on fuel emissions. The Raspberry Pi is good for the environment as it runs on a very low voltage making it extremely economical and its hardware is known for its prolongation. The small size of it combined with its computer power makes a perfect foundation for small projects as well as environmentally friendly.The Raspberry Pi Foundation is a non-profit organisation. Raspberry Pi devices have always stayed low-cost, and consequently are in ever-increasing demand, thanks to it being manufactured in the UK. The skeleton of the EDD is made using 3D printing material called Poly Lactic Acid (PLA) Filament. It has become one of the most common materials for 3D printing because it is easy to print, biodegradable and bio-derived from corn and other bio-materials.
Global Challenge 7: Affordable and Clean Energy
The EDD is powered by rechargeable batteries. The main reason for this is that heavy metals, corrosive materials, and other hazardous chemicals combined with unsuitable (all-too-common) disposal results in poor environmental news for the world. According to a study by Uniross carried out in 2007, the production of rechargeable batteries has the following advantages over disposables (comparing serviceable life):– 23 times less potential impact on non-renewable natural resources– 28 times less potential impact on global warming– 30 times less potential impact on air pollution (ozone pollution)– 9 times less potential impact on air acidification– 2 times less potential impact on water pollutionA double-a battery can pollute around 20 square meters of land or 400 litres of water. These small and seemingly harmless things can cause diseases of human and all living creatures on earth as when the battery ends up in the ground, it reveals harmful substances that poison the soil, then it goes to our rivers and lakes from where it can be vaporised. Consequently, we all breathe this air. Furthermore, 200 million double-A batteries are sold in the UK alone when you can simply use your micro USB cable to recharge. talking about money you can reduce your expenses for batteries by using a micro USB cable to recharge the power bank in the Entry Denial System Device. An alternative option is to replace the battery with the mono crystalline solar panel if the device is kept near a window so it would constantly keep the device working. Moreover, the life span of a solar panel is around 25-30 years and would also keep the device working for a longer time as sunlight is a renewable source of energy.
