“…As the stability of the methane carrier catalytic element is greater than or equal to 7 d, the coal mine safety regulations formulated by the National Administration of Coal Mine Safety require that methane sensors and portable methane detection alarm devices using carrier catalytic elements must be adjusted with air samples and corresponding methane standard gas samples every seven days [20]. The adjustment of the mine gas sensor is divided into two steps: (1) zero-point adjustment, that is, in fresh air observe whether the sensor reading is 0; (2) in the standard gas sample (for example, the gas concentration is 2%), make sure the reading of the sensor is consistent with the concentration of the standard gas sample. Both of these scenarios will be encountered in actual mine surveys.…”

Due to the increasing deployment of the Internet of Things (IoT) in the mining industry, portable gas monitoring devices have been widely used. Sensor calibration of large-scale portable gas monitoring devices is becoming an urgent problem to be solved. An online sensor calibration algorithm based on n-tuple and opportunistic communication is proposed based on the specific characteristics (i.e., ‘single-sensor, multi-position’ and ‘multi-sensor, single-position’) of each portable gas monitoring device employed. In this paper, data collected from portable and fixed sensors were defined as multi-dimensional data points and gas monitoring data pairs, respectively. The cluster-based self-adaptive weighted data fusion algorithm and multi-period single sensor reliability fusion algorithm were proposed and used for overall judging. The overall judgments were broadcast to each wireless access point by network, and the reliability of the calibration information transmission was enhanced by opportunistic communications. The simulation results revealed that efforts required for the calibration of portable sensors were reduced significantly, and their reliability was improved.

“…Most of these sensors show an electrochemical reaction when exposed to a specific gas. Ma H. et al proposed a high-temperature silicon cantilever microheater with low power consumption to detect low concentrations of methane gas [ 2 ]. All these solid-state gas sensors are inexpensive, small, and suitable for mobile measurements.…”

In the high precision molecular spectroscopy, the temperature of gas absorption cell is accurately measured. In this paper we discuss the factors affecting the measurement accuracy of temperature sensor employing platinum resistance in a resonant quartz crystal tuning fork (QCTF) detector based wavelength modulation spectroscopy (WMS). A bridge temperature sensor powered by a dual constant current source (DCCS) is proposed. The DCCS was controlled to keep the constant current of 1mA in this work. Furthermore, we used the 3-wire measurements powered by DCCS to eliminate the impact of lead resistances and self heating of the platinum resistance so as to reduce measurement errors. A piecewise linearization model by linear approximation algorithm is employed to evaluate the measurement calibration and increase the measurement accuracy. Detection of trace methane (CH4) was demonstrated using a near infrared distributed feedback diode laser near 1.653 µm and a single pass gas absorption cell with an optical length of 20 cm. An example of the temperature sensor employing Pt100 with 3-wire measurement is developed in the detection of CH 4 with the temperature range from 0 • C to 100 • C. The controllable DCCS method is demonstrated by the measurement results of the deploying Pt100 sensors. Experimental results show that the accuracy of our proposed temperature sensor is improved in comparison with the conventional platinum resistance thermometer. The measurement accuracy is relatively increased due to employing the piecewise linear approximation model. The results also show good performance for measurement calibration, especially for high temperature region.

“…Commercially available electrochemical on-chip sensor technology is based on a catalytic action, often driven by auxiliary temperature. The micro-hotplate and micro heaters solutions, partially using advantages of MEMS fabrication technology, were proposed to lower the energy demands for these catalytic sensors [ 144 ]. This class of gas sensors still suffers from stability and degradation issues [ 145 ], and still needs improvements regarding their energy efficiency [ 146 ].…”

Air quality depends on the various gases and particles present in it. Both natural phenomena and human activities affect the cleanliness of air. In the last decade, many countries experienced an unprecedented industrial growth, resulting in changing air quality values, and correspondingly, affecting our life quality. Air quality can be accessed by employing microchips that qualitatively and quantitatively determine the present gases and dust particles. The so-called particular matter 2.5 (PM2.5) values are of high importance, as such small particles can penetrate the human lung barrier and enter the blood system. There are cancer cases related to many air pollutants, and especially to PM2.5, contributing to exploding costs within the healthcare system. We focus on various current and potential future air pollutants, and propose solutions on how to protect our health against such dangerous substances. Recent developments in the Organ-on-Chip (OoC) technology can be used to study air pollution as well. OoC allows determination of pollutant toxicity and speeds up the development of novel pharmaceutical drugs.
