Dynamic control of adsorption sensitivity for photo-EMF-based ammonia gas sensors using a wireless network.

This engineering paper proposes a control method for a photo-electromagnetic field (EMF)-based ammonia gas sensor that uses a wireless network and adjusts illumination light intensity. It reports that measurement error is minimized over 3800 ppm ammonia when the concentration corresponds to an optimal illumination…

Design and implementation of a wireless sensor network-based remote water-level monitoring system.

This article reports an engineering implementation of a wireless sensor network-based remote water-level monitoring system. The system includes field sensors, a base station, a data center, and a web publishing module, and is described as providing real-time monitoring and anti-jamming capability. The authors state…
