To compensate for changes in ambient temperature, thermal flow sensors are usually heated to a constant temperature above ambient temperature. This operating mode, however, requires an extra ambient-temperature sensor. Using a simple model, it is shown that for a two-dimensional thermal flow sensor, similar compensation may be obtained by using a constant heating power, thus eliminating the nee...

Sistem manajemen air merupakan bagian penting dari kota. Pengelolaan melibatkan penyediaan sesuai dengan kebutuhan nyata dan tanpa membuang-buang air. Oleh karena itu, sangat untuk mengukur laju volume aliran monitoring distribusi (flow sensor) konvensional menuju ke pelanggan mencatat penggunaan melalui metering yang ada di sisi secara manual. pengukuran debet (metering) perlu menyediakan tena...

Electronic musical instruments consist of some kind of sensor/input system, software to interpret the sensed data, and sound synthesis. Electronic instruments should provide intimate and satisfying control over sound comparable to the control that an expert musician has over a fine acoustic instrument. These elements are necessary for such electronic instruments: low latency and virtually no ji...

Electronic noses utilizes an array of chemical sensors of different specificities which responds to the volatile organic compounds present in the gases. The use of electronic chemical sensors in an array design with coupled signal conditioning and appropriate pattern recognition system is capable of identifying complex odours.Such an artificial gas sensing system is called 'electronic nose'. Th...

Sensor The thermal sensor is designed for quick response, long-term stability, and high reliability. The sensor tube in an Aera mass flow product has a very small diameter and mass to ensure the fastest response to any change in gas flow conditions. Bypass Also known as the flow splitter, the bypass maintains a constant ratio of gas flow through the sensor and main flow path, dividing the gas s...

In recent years, owing to the significant applications of health monitoring, wearable electronic devices such as smart watches, smart glass and wearable cameras have been growing rapidly. Gas sensor is an important part of wearable electronic devices for detecting pollutant, toxic, and combustible gases. However, in order to apply to wearable electronic devices, the gas sensor needs flexible, t...

Modern molecular electronic transfer (MET) angular motion sensors combine high technical characteristics with low cost. Self-noise is one of the key characteristics which determine applications for MET sensors. However, until the present there has not been a model describing the sensor noise in the complete operating frequency range. The present work reports the results of an experimental study...
