Resch et al. [39] summarise and discuss the whole chain from data retrieval, processing, analysis and visualisation. The general design and structure of such a chain is depicted in Fig. 2, starting with generalised sensors. These sensors can be traditional fixed monitors, but can also be mobile sensors installed on cars, ships or at short-term locations, for example on lampposts. These mobile or moveable sensors can be equipped with a geo-positioning system (GPS) to be employed in geo-information systems (GIS) (e.g. [40]). These applications have been made possible by miniaturisation of the GPS as well as the transfer of data by mobile phone systems.

Abstract A brief overview is given for a variety of sensors for the detection of chemical warfare agents (CWA) semiconductor thick- or thin-fihn gas sensors with oxide and noble metal additives, surface acoustic wave (SAW) sensors with a polymer membrane, and an ion mobility sensor (IMS). This is followed by discussion on the preparation methods for the sensing materials employed in semiconducting devices, and SAW sensors are introduced.The chapter closes with the results and observations from the examination and study of these devices. 

It has also been established that the RBC itself could act as a mobile sensor for hypoxia [61]. The mechanism works as follows Under conditions of low oxygen and pH, the RBC releases ATP, which binds to purinergic receptors on the endothelial cells. This leads to the production in the endothelial cells of the vasodilator NO. Since the most likely location for hypoxia would be in or near the venular network, the local vasodilatory response to NO is propagated to upstream vessels causing arteriolar vasodilation (see the following section on Coordination of Vasomotor Responses).

One potential approach for improved accuracy is sensor fusion, whereby readings from multiple, functionally different sensors are combined to estimate the soil properties of interest. For example, a commercial mobile sensor platform (Fig. 2.6) combined the soil pH sensing system described in reference (155) with soil apparent electrical conductivity (ECa) sensing. As ECa provides a strong indication of soil texture variations, the combination of the pH and ECa data was useful for establishing lime requirements. An NIR reflectance sensor was later added to this multi-sensor platform. ...
