Recently, the society change makes people require high safety guarantee, so home safety become one of the brand new lessen to us. The great improvement of technology cause the traditional keys no longer remain safe, that’s why nowadays many countries and enterprise pumps money and talent into developing high technological electronic lock, which are both unique and high-complicated, so it can prevent itself be decoded effectively. Along with the smartphone and Embedded system popularized, the time to develop IOT, is mature. This essay is target to use smartphone combine with IoT, GSM and Morse code developing a new model of intelligence lock, in order electronic lock to jump out of the foretime form.
This essay mentioned about the IoT-Based Morse code, using the LED in Android programmed smartphone to send signal to the embedded system’s photosensitive element. The signal strength use fuzzy logic to adjust the light sensitiveness, which influenced by environmental light, and encrypt via the Morse code, then the embedded device will interpret the code and upload to the IoT. This essay use micro-controller to receive the encrypted Morse code’s light and interpret by Linkit Smart 7688 Duo module then upload to the IOT. If not using this way to decode, not only will we upload the information to the cloud, also sent message to the user’s Smartphone to alarm them, in order to reach home safety guarantee.
In application, each decoder will be given different codes, it displays the independence and highly-recognized characters of Morse code. Although people get decode via Smartphone’s photosensitive element, but the Morse code have high recognizable rate up to the decoder.
Key words: Fuzzy control , Morse code , Android , Internet of Things , GSM
