Gas Sensor - an overview | ScienceDirect Topics

Gas sensors are generally understood as providing a measurement of the concentration of some analyte of interest, such as CO, CO2, NO x, SO 2, without at this point dwelling on the plethora of underlying approaches such as optical absorption, electrical conductivity, electrochemical (EC), and catalytic bead (see Section 3).

Gas Sensor - Arduino Project Hub

21/08/2020· About this project. This gas sensor uses a MQ-2 gas sensor to indicate if there is gas in the area. so the sensor has a threshold value (the threshold value is around the amount of smoke in there is a fire) in that if it goes above it starts alerting people in the vicinity. The alert just shows a red led and starts beeping.

Gas detector - Wikipedia

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
