Abstract
This article reports a sub-GHz, 868MHz, battery operated miniature sensor node with a fabricated helical Printed Circuit Board (PCB) and a third party whip antenna for Internet of Things (IoT) applications. CC1310 System on Chip (SoC), a sub-GHz family wireless microcontroller, is used to design the system. A HDC 1050 temperature and humidity sensor is interfaced with the microcontroller. The system has the desirable benefits of being small and inexpensive, long battery life and capable of long transmission range. The path loss exponent is calculated from Received Signal Strength Indicator (RSSI) values in two environments - free space and across concrete obstructions. A wireless sensor network is incorporated into a cloud platform for real time monitoring, and web application has been developed for data display and analysis. To validate the proposed IoT system, the measured data is compared with an independent meteorological data set from the Indian Meteorological Department, Cyclone Warning Centre, Visakhapatnam.
