Natural Gas Cutoff Matthew greb

In this project, we were to design a circuit that would act as a safety valve for a gas circuit. Based on the 4 burner sensors (A, B, C, and D) an emergency cut off valve would either be closed (0) or open (1). It was to remain open so long as at least 3 of the 4 burner sensors produced a 1 (or "safe") value. The 4 burner sensors were also to control a control circuit, which was to turn on at ...

positive sensor response. These gases or vapors tend to be caught in the filter and can saturate the filter before desorbing over time. As a result, after exposure to a hydrocarbon or VOC, a sensor may need time to stabilize and show a reading, even after the substance is no longer present. In this case, the substance works its way through the filter and is read by the sensor upon breakthrough ...
