co2 sensor for human detection

A novel detection method of human serum albumin based on ...

· We developed a novel “turn off-on” sensor for human serum albumin (HSA) detection based on CuInZnS quantum dots (CIZS QDs). The photoluminescence (PL) of QDs can be “turned off” by Co(II) first. Because of the strong binding ability of HSA with Co2+, Co2+ can be removed from CIZS QDs with the addition of HSA. As a result, the PL of CIZS QDs probe can be “turned on” with an ...

CO2 Sensor Occupancy Detection |

A group of researchers at the University of California in Berkley have designed an algorithm that can count the number of people in a room when only the CO2 level is known. The study, titled “ Sensing by Proxy: Occupancy Detection Based on Indoor CO2 Concentration ” used SenseAir’s K-30 carbon dioxide sensor module for occupancy detection.

Sensing - KEMET

Food detection – It is not about detecting the presence of food but rather detecting the status of food. The sensors are built on a similar principle as gas sensors. As foods reach spoiled states they emit gasses that may undetectable by the human olfactory sense but might still appear to be edible. To prevent the consumption of unsafe foods, sensor’s such as KEMET’s can be used.

A portable sensor system for the detection of human ...

· If CO 2 is detected, the more sophisticated aIMS detector and the aldehyde sensor can then be used to search for a signature reflecting human-specific VOCs. Hence, the combination of CO 2 and volatile detectors (aldehyde sensor and aIMS) provides a highly specific analytical tool, with which first responders or security personnel can detect the presence of trapped or hidden human beings …
