【實用生活app】iDoorOpen|最夯免費app-綠色工廠好玩App

iDoorOpenThe sensational DIY application: Digital door opener with the SmartPhone.With this app and the appropriate electronic (DIY) Door opener you can unlock your door with your SmartPhone - either your hone, your office or any room worthy of protection. The transmission of the access numbers is visually over the built-in camera flash light. Important notes:For practical and sensible operation of this application, you need a smartphone with camera flash and a special accessory - an electronic digital door release with an optoelectronic extension (photosensor). Experienced electronics tinkerer can build this (DIY) hardware by themself (in the app this is clearly shown on the photo sensor). For more information on a complete, functional Door lock number device, contact HMB | TEC on the website or webstore under www.hmb-tec.deOperation:Assuming you have an appropriately modified digital electronic door opener device, you can send with this app via the built-in LED flash light a digital number to the door opener. If the transmitted number matches the match previously stored number in the same procedure, the door opener is a signal and causes the door opener. You can (000000 to 999999) and enter assign "my home", "myOffice" and "my secret" keys in the app 3 numbers with 6 digits.Since this is one of HMB also in this app | is denoted as TEC DIY App application, you can build the necessary hardware and himself. However, for the self you need extensive knowledge in microcontroller technology, because you need to receive the signal transmitted by Bitzlicht light with a photo sensor and perform an evaluation. However, the communication protocol is very simple. The six digits are encoded as PWM light signals. In this case, a start bit is sent to the length of 50 ms for synchronization. After an interval of 50 ms, the 20 bits of data follow. The data bits can have the logic states "0" or "1". A "0" is translated as a subsequent light signal with 20ms interval of 20ms. The "1" also corresponds to a 20 ms pulse of light, but in this case the break is defined as 40ms. After the 20 data bits for 3 sum bits are sent. In the current version, but these have the fixed bit string of "101". The send operation takes about 2 seconds. During this time the SmartPhone must be positioned in close proximity to the photo sensor of the door opener. The transfer is visualized in the app in the form of an animated wave representation.This optical transmission method applied here with pulsating light has the advantage that the transmission works only for a short distance and therefore is very bug-proof and tamper-free. The chosen encoding comprises nearly a million different numbers.For further questions and information you can contact directly to the app developer.

Please note that a very small percentage of individuals may experience epileptic seizures when exposed to such light patterns or flashing lights. If you have an epileptic condition, consult your physician prior to using this app.
