Portable electronic nodes for a sensor network [Articol]

Abstract

To capitalize on the research on metal oxide-based sensors that is being intensively studied by our research team, there is a need to connect these sensors into devices capable of receiving, storing and, if necessary, transmitting measured data. We are also investigating the mechanics of sensor detection using chemistry and applied physics. To achieve this goal, there are some impediments that must be overcome, such as the method of data acquisition, the power consumed by the device, the stability over time with a subsequent correction, the distance to which measured data will be transmitted and others. Another aspect is the size and portability of these devices with built-in sensors. This paper presents some concepts that provide solutions to the problems presented. These devices are important for monitoring environmental parameters with application in agriculture, cellars, production halls. Another possible use is to incorporate them into drones, which will potentially increase their mobility and detection range.
