Low-power device for wireless sensor network for Smart Cities

Nowadays, Wireless Sensor Networks (WSN) provide new monitoring capabilities useful in the different dimensions of Smart Cities to gather information in environment, healthcare, transport, logistics and security applications. However, wireless communication frequently requires a high power consumption which reduces the autonomy of the system. In this paper, we propose the implementation of a WSN using low-power devices for the transceiver process. This system combines sensing and data storage in a compact device with low power consumption. One device is a wireless node sensor, and the other device consists in a data storage component. The wireless network made a connection by multichannel RF communication operating at 315, 433, 868, and 915 MHz, Data storage device used a Real Time Clock (RTC) and external memory (EEPROM) to register sensor measurements. Overall system lets improve the data management using both, storage and transmission data.
