Air Pollution Detector : 11 Steps (with Pictures ...

For MQ sensors we use the graphs on the device datasheets to qualitatively assess the data. When the resistance value drops to less than half of the resistance in air, it is likely that the devise is detecting the target gasses. When resistance drops by a factor of 10, the levels of target gas are likely around 1000 ppm, close to the legal safety limit. Once we obtain approximate ...

Medical O2 Sensors and OEM Components

O 2 Sensors* in Medical Devices Optical oxygen sensors are small and can be manufactured in various designs. As the sensor itself can be physically separated from the electronic measurement components, measurements can not only be performed non-invasively, the sensor can also be placed in easily exchangeable parts - like single-use flow-through cells - for sensor replacement.
