Power management of a wireless sensor node with solar energy harvesting technology

Purpose - Power management of a wireless sensor node is important and needs to be designed efficiently without wasting excessive energy. The purpose of this paper is to report on the improvement of the power management of a wireless sensor node. Design/methodology/approach - The design involves the implementation of solar recharging technology with single-ended primary inductance converter (SEPIC) on a wireless sensor node in order to achieve the improvement in power management. Findings - The combination of the solar recharging technology with SEPIC converter shows promising results for efficiently supplying the power to the wireless sensor node. Research limitations/implications - The design idea can be extended for many other electronic sensor applications, which can help to ensure an efficient power management of the sensor nodes. Originality/value - The proposed design model demonstrates a new idea towards reduction of energy usage for wireless sensor nodes.
