“…The rate was adjusted gradually upon the difference between the measured value and the average of limits. The incident and the following measurement were considered to be of higher importance than measurements of typical values as it is presented in the column for value k. Despite the higher importance of the incident this message gain function value is surprisingly low compared for example to the previous message at position 6. It happened so due to the fact that delay in transmission was longer.…”

In this paper, some issues of building a reliable, distributed measurement system for monitoring of water quality in reservoir Lake Dobczyckie are presented. The system is based on a measurement station that has the shape of a floating buoy which is supposed to be at anchor on the reservoir. Wireless data transmission problems that were encountered during the development of the buoy, modeling a radio link, and measurements of actual signal strength on the reservoir are discussed. A mathematical approach to procedures of early situation assessment was conducted, and specialized procedures were designed for measurement stations of the system. It is also discussed how such computations can improve a qualitative assessment of system performance in terms of real-time messaging.

“…This provides an opportunity for instant monitoring of water quality in at least few most important parameters mentioned before. Such a station becomes part of a distributed, highly scalable and vital decision support system [6]. Each measurement station can compute the numerical representation of situation assessment.…”

“…The energy consumed during a measurement cycle (E Meas ) includes the charge Q (3) consumed by the control processing unit (CPU) to process the measurement algorithm based on (3), the charge consumed when charging C c from V TL to V DD , the clock (Timer) charge consumption during T m , T r , and T o , and the charge consumption caused by each Schmitt trigger input voltage transition (Q H j , j = m, n, or o) as follows:…”

“…It is one of the main design bottlenecks for incoming new technologies such as powerless sensor nodes integrated in passive radio-frequency identifier systems [1], [2]. Although the main research efforts have focused on lowering the energy spent by the communication system [3], the measurement process can spend more energy whenever not all the measurement data are transmitted.…”

Abstract-This paper analyzes the energy consumption of direct interface circuits where the data conversion of a resistive sensor is performed by a direct connection to a set of digital ports of a microcontroller (μC). The causes of energy consumption as well as their relation to the measurement specifications in terms of uncertainty are analyzed. This analysis yields a tradeoff between energy consumption and measurement uncertainty, which sets a design procedure focused on achieving the lowest energy consumption for a given uncertainty and a measuring range. Together with this analysis, a novel experimental setup is proposed that allows one to measure the μC's timer quantization uncertainty. An application example is shown where the design procedure is applied. The experimental results fairly fit the theoretical analysis, yielding only 5 μJ to achieve nine effective number of bits (ENOB) in a measuring range from 1 to 1.38 k . With the same ENOB, the energy is reduced to 1.9 μJ when the measurement limits are changed to 100 and 138 k .

Abstract. In this article, the RObject concept is first introduced. This is followed by a survey of applicable energy scavenging technologies. Energy is a key issue for the large scale deployment of robotics in daily life, as recharging the batteries places a considerable burden on the end-user and is a waste of energy which has an overall negative impact on the limited resources of our planet. We show how the energy obtained from light, water flow, and human work, could be promising sources of energy for powering low-duty devices. To assess the feasibility of powering future RObjects with technologies, tests were conducted on commonly available robotic vacuum cleaners. These tests established an upper-bound on the power requirements for RObjects. Finally, based on these results, the feasibility of powering RObjects using scavenged energy is discussed.
