This project is very useful in our current environment in which data transmission through mobile gadgets is often used. The concept of this project is to allow you to connect and gather data from a battery-free wireless transmitter using your own smart device. This incorporates two main components, the CYBLE-022001-00 EZ-BLE™ PRoC™ module and the energy harvesting PMIC. The CYBLE-022001-00 supports a number of peripheral functions (ADC, timers, counters, PWM) and serial communication protocols (I2C, UART, SPI) through its programmable architecture.
The wireless transmitter node can be installed in any place and is powered by light energy that is harvested from its surrounding environment. This is possible by coupling Bluetooth Low Energy (BLE) with its energy harvesting power management IC to enable a true battery free device. The wireless transmitter node use Bluetooth Smart as an energy efficient way to transmit data to a smart receiver. It is pre-programmed with a unique, very short data string that is sent to a smart receiver, typically a smart phone, using the Advertisement mode of Bluetooth Smart. The Advertisement mode is usually used to transmit pairing information and defined to use very little energy. Using the unique data, your smartphone goes to the Internet and pulls down content that's related to where you are or what you're doing.
The transmission range can be adjusted, so the content displayed can be very focused on the immediate area, or widened out to relate to a general area. Wireless Sensor Nodes use this mode not only to send the unique data, but also to send additional data such as temperature or humidity that has been collected by an embedded sensor. The smart device receives both sets of data and sends it to the Internet and to be stored in a database.
