In this research, improvisation was carried out by modifying the market IR thermopile which functions as a thermal conductivity detector to measure the concentration of CO2 gas in the gas mixture. Four thermopiles are configured with a Wheatstone bri

A simple and effective thermal conductivity based CO2 gas sensor has been successfully developed. The CO2 sensor consists of a modified IR thermopile sensor without an IR window. The thermopile is heated by the AC current that is applied through the

A two-dimensional double-cage flow meter for detecting very small rates of airflow using ionized air is demonstrated. A corona discharge inside a Faraday cage generates an ion cloud that expands outside the Faraday cage driven only by its own charge

In this research, an acoustic sensor has been successfully built to measure the concentration of CO2 gas in a mixture of gases (N2 and CO2). The nitrogen and carbon dioxide gases used are ultra-high purity (UHP) gas. The measurement parameter used is

Tubular connection integrity is a key to short-term and long-term well integrity. The stress on the tubular and the connection, particularly in high-pressure, high-temperature wells, creates challenges for connection providers. Proper selection of ma

In ear thermometers and similar applications, thermopile sensors have to face a challenging thermal environment. The steady-state sensor temperature as well as the change of sensor temperature, heat flow, and thermal gradients have a significant impa

We use a general second-order mathematical description of sensing, sensory information acquisition and pre-processing to treat biological vision in analogy to a technical sensor. Using very early visual processing by the retina, i.e. the retinal rece
