“…To achieve further reduction of the sensing circuit power consumption, the 'differential' measurement procedure has been proposed in [17] and [18]. Instead of widely used Wheatstone circuit the authors propose to employ a single active gas sensor embedded in the voltage divider circuit (see Fig.…”

“…In this case the supply voltage used to heat the sensors up may vary in a wide range (from 0 to 3 V) and, therefore, can not be used for consecutive supplying of digital circuit. This problem was addressed in [18] by designing a circuit with two separate "analogue" and "digital" power supplies. The analogue power supply is composed of three 1.5 V C-sized alkaline cells and supplies the gas sensor system through a linear regulator.…”

“…In order to reduce the power consumption, we have used and tested non-conventional sampling and processing strategies, introduced in our previous work [14], [15]. The idea is to reduce the amount of energy required to perform a measure by limiting the time the sensor is switched on (from 5 to 0.5 s).…”

Wireless Sensor Networks (WSN) are a versatile technology that offers the ability to monitor real-world phenomena in detail and at large scale in scenarios where wired infrastructures are inapplicable or expensive. In this paper we present an ad-hoc WSN deployment for indoor environmental quality monitoring in office buildings. The indoor environmental quality and balance between inhabitant comfort level and power demands are the main objectives of this network. The presented system consists of 19 sensor devices continuously measuring vibration, temperature, humidity, light, and carbon dioxide levels in working areas. The power load of the building is measured by dedicated current sensor devices. Preliminary laboratory tests and data sets collected during 4 months of real world operation show that our system provides an accurate monitoring of indoor environmental parameters delivering high data reliability with an estimated lifetime exceeding 1.5 years, without the gas sensors. The paper presents the HW/SW architecture, the network infrastructure of the deployment and analyzes real measurement data.

“…Other kind of optimization were introduced in the hardware of nodes [11], [15], achieving significant reduction of wasted power when the device is in idle or sleeping state. Recently Somov et al [16] have presented a monitoring device that necessitates very little energy, those have developed a new catalytic sensor and the adequate sampling and processing algorithm. This choice, although interesting, is not cost effective.…”

We present an environmental monitoring system based on wireless sensor network for air quality measurement and natural gas leakages. The system is based on catalytic offthe-self available gas sensors and on a novel strategy of sampling and processing which permits to reduce the energy consumption of one order of magnitude. The characteristic of the sensing device has been extracted both with the standard utilization and the new proposed approach, to compare and validate our results. Moreover the importance of the humidity present in the environment has been taken into account and included in the model, because it severely affects the measurements. The wireless sensor network developed has been also extended using a smartphone to enable data sharing over internet and to enhance portability of the overall system.
