Abstract:
In this paper, a flexible wireless sensor platform with an auto sensor identification scheme is presented. Our presented flexible wireless sensor platform consists of sensor modules, and each sensor module is a part of the sensor system and in charge of one job in the system, such as computation, communication, output or sensing. Users can stack multiple modules together to build a unique sensor system. Since users are able to easily replace one module with others, our platform is highly extendable and reusable. A low-cost sensor identification scheme is proposed in this paper to detect which sensor is mounted on the platform automatically. This scheme utilizes a unique I2C address to identify the sensor type. A low-cost Electrically-Erasable Programmable Read-Only Memory (EEPROM) only needs to be setup in the non-I2C sensing modules. Furthermore, a firmware initialization process is also adopted to achieve the sensor identification mechanism. To demonstrate the proposed platform, we show an ambient temperature detection application in the paper. The results show that the proposed platform is suitable for academic researches and industrial prototype verification.
