A Novel Solar Harvesting Modular Wireless Sensor Mote for Green House Applications: Design & Implementation

This paper presents the design of a cost-effective and compact wireless sensor node (WSN), which is able to harvest energy from limited sunlight environment when it is connected to a 1.9V power supply. A modular and compact hardware design structure is featured to the node. Comparing to the short-range WSNs on the most current market which function under the 2.4GHz dense spectrum, a low power medium range 915 MHz transceiver is utilized in the present version of the node, for the purpose of minimizing electromagnetic interference. In order to collect the aggregation data from every single allocated nodes, and managing the obtained packets energy efficiency, an innovative energy management system is proposed. To envision the applications of the wireless sensor node, the main usage will be in agriculture industry, especially in the greenhouse monitor systems. The considerations of design, simulations, and experimental results are presented in this paper.
