Implementation of a Wireless Sensor Node for Multi-Purpose Blockchain Applications

Recently, wireless sensor networks (WSNs) have attracted a lot of interest due to their applications in
numerous fields, such as home security, environmental monitoring, critical infrastructure protection and
energy power. Moreover, WSNs are combined with blockchain to provide trust, transparency and
traceability for electrical power systems, military applications, and commercial applications. This article will
present the main units of a sensor node used and the implementation of a sensor node used for multi-purpose
applications in the energy field. Also, we will present the hardware implementation of a low-power and low-
cost sensor node designed for measuring environmental parameters and storing on blockchain.
