Abstract: To reduce the risks of natural disasters, proactive use of environmental data is important. However, securing electricity in rural areas is often challenging. Thus, IoT gateways powered by power-over-fiber (PoF) are required. In this work, we develop an intermittent IoT gateway by implementing a task-aware module operation algorithm suitable for intermittent IoT sensing with power-limited PoF. The algorithm selectively powers the necessary modules and minimizes their operating time during the active state. As a result, power consumption in the active state is reduced by 56% compared with previous work, in which almost all modules were activated. Furthermore, the algorithm suppresses the temperature increase of the transmitter, one of the most power-hungry modules, by ∼11K.
