| Abstract: | In June 2010, the Bluetooth SIG adopted the first version of Bluetooth that includes the low energy specifications (4.0). Ble has been designed to allow devices running on a small energy budget to communicate with host stations such as mobile phones or personal computers. Bluetooth low energy is primarily meant to be used in applications that require small batteries. In this work we investigated the suitability of that new wireless protocol for a battery-free application. We chose a simple and yet useful application scenario, where temperature and humidity are measured in an office environment and the results are wirelessly sent to a host. The use of the new sensor SHT21 from Sensirion allows temperature and humidity to be precisely measured with a small energy budget. For sensors to be moved and placed conveniently, a wireless system based on the EM9301 Ble radio of EM Microelectronic is implemented. The EM6819 is used as microcontroller to control the system. Energy autonomy is provided by a flexible and small solar cell from G24i. Temperature and humidity data can be displayed or transferred to the right place by using the appropriate PC or mobile phone fitted with the wireless link. As far as we know, this is the first work of this type using a battery-less sensor and Ble for communication. |
