Although wireless smart sensor platforms have been available over a decade, only a limited number of full-scale wireless smart sensor–based structural health monitoring implementations have been realized. Most wireless smart sensor platforms that are validated in full-scale implementations have now become obsolete and are no longer commercially available. While wireless sensing capabilities have grown, presenting significant opportunities, obstacles to wide application of wireless smart sensor for structural health monitoring exist both in terms of hardware and software. This article assesses the efficacy of the Xnode, a new wireless platform whose development has been driven by structural health monitoring requirements, as well as lessons learned from several full-scale wireless smart sensor deployments. The capabilities of the platform are evaluated in comparison with other commercial wireless smart sensors, in terms of hardware, software, and mechanical design. Extensive laboratory and field testing is employed to validate its performance on three aspects: fidelity of data acquisition, reliability of wireless communication, and efficiency of power management. Test results demonstrate the capabilities of the Xnode to support full-scale, high-fidelity data acquisition for civil infrastructure. In addition, the new sensor platform provides several significant benefits to extend the use of wireless smart sensors to a broader class of structural health monitoring applications, such as sudden event monitoring and real-time and control applications.

A platform for a flexible, smart sensing system using available hardware components for monitoring the operation of a greenhouse is presented. The smart sensor is based on a ZigBee MCU embedded system with multiple connectivity options to facilitate digital or analogue sensors as well as the necessary peripherals for energy management and programming/debugging. A number of physical parameters may be simultaneously monitored by each node, such as temperature, relative humidity, CO2, light intensity, soil pH / moisture through appropriate sensors. Basic functions, such as sensor differential detection and measurement consistency may be performed at the smart sensor. A central node, also acting as the Zigbee network coordinator will concentrate the various measurements through the wireless network, act as a local display and also forward the information to a back-end. The back-end will provide proper measurement visualization (including history) through any web-enabled device, as well as services such as alert notification in hazardous situations (e.g. flood / heating failure).
