Comment Capteur de Gas MQ2 MELEE

Gas Sensor Arduino Project Hub

20200821· This gas sensor uses a MQ2 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. This idea is very helpful and is used on a daily basis with the smoke alarms that a lot of ...

Gas Sensor Library for Proteus The Engineering Projects

20160502· In this Gas Sensor Library for Proteus, I have added eight different Gas Sensors, which are used for detection of different gases. As we all know that Proteus is a simulating software so it won’t be able to detect the gas in real in Proteus. So, that’s why I have placed a Test Pin in each of these sensors so when you make this pin HIGH, then it means the gas is present and if this Test Pin ...

Interfacing MQ2 Gas Sensor with evive STEMpedia

The MQ2 Gas sensor has a builtin variable resistor that changes its value according to the concentration of gas. If the concentration is High, the resistance decreases, if the concentration is low, the resistance increases. Besides the builtin resistor, it is necessary to include load resistor, Load resistor serve to adjust sensor sensitivity and accuracy, it’s value can range from 2k ohm ...
