Simple Smoke Detector Alarm Circuit MQ2/MQ6

· Whenever the sensor detects smoke, it reduces its strength, because of this reduction in resistance, the voltage across the base of the transistor rises. Now when the voltage at the terminal of a transistor becomes greater than or equal to , then the transistor turns on, and the LED lights up, and the buzzer also starts beeping. And when we do not find smoke, both the indicator components ...

MQ 2 Gas Sensor IoCT

Figure 2: Schematic of MQ2 Gas Sensor from Datasheet. 2The MQ 2 sensor is a metal oxide semiconductor (MOS), also known as a chemiresistor. MOS sensors measure the change in resistance when gases are present. This type of sensor requires the gas to encounter the sensor for a chemical reaction to occur. This chemical reaction causes a change in resistance, which is then measured to …

Smoke Sensor Module Energia Zero

A smoke sensor is a device that senses smoke, typically as an indicator of fire. Commercial and residential security devices issue a signal to a fire alarm control panel as part of a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible or visual alarm from the detector itself. The Analog Smoke/LPG/CO Gas Sensor (MQ2) module utilizes an MQ2 as ...
