Grove - gas & dust sensors

The sensor device increasingly found in the programs of air quality monitoring. Compared to traditional methods, with our sensors it is possible with minimal costs to perform the measurements of air pollution in any place. In facilities, construction of character in residential and labor, sensors, quality parameters of air, such as dust or gas hazardous to life and health, to ensure the security cooperating with acoustic alarm in case of detection of the sensor exceeding the permissible level of pollutants in the air.

As built and how they work today, sensors are used clean air?

Currently used several types of gauges clean air - among them are electrochemical sensors in which the measurement process is the chemical reaction of the gases contained in the air electrode with the measuring equipment placed in a liquid medium. In sensors of electrical and semiconductor devices, based on metal oxides, the gases contained in the air react with the surface of the sensor by changing the resistance of its secondary measuring circuit. Another design, used in the air quality monitoring sensor fotojonizacyjny. Its principle of operation is based on ionization of molecules of organic compounds, which eventually causes the flow of electric current in the secondary measuring circuit of the sensor. Air pollution can also be controlled via optical sensors, which control how molecules of gases or dust present in the air affect and create a new cosmic light. Optical sensors can detect the presence of carbon monoxide (carbon monoxide) and of carbon dioxide by measuring the amount of absorbed infrared light.

What factors affect the accuracy of measurement using sensors monitors the parameters of air quality?

The parameters of the measuring signal received from the sensors clean air not only affects us the most interesting concentration of gas and dust in the air, but also other environmental factors and equipment, such as the presence of undetectable sensors are substances that can interfere in the measurement, temperature, humidity, pressure, and drift of the signal depend on the electromagnetic parameters of the measuring system, for example, with higher air pollution, the measurement signal may be attenuated due to molecules of other substances in the air, which can lead to falsification of the measurement. The measurement accuracy is also affected by the project, the design, the purpose of the sensor interacting with the measuring system, for example, a microcontroller. Due to fluctuations in environmental conditions, the sensor calibration may not be sufficient, and retrieving exact and approximate to each other measurements in similar environmental conditions, although in different locations of the measurements, it can be difficult to achieve. Despite this, sensors of gas, dust and air cleanliness Grove successfully perform the hardware settings and professional monitoring stations.
