MQ2 Gas Sensor
In this simulation, students explore how an MQ2 Gas Sensor detects the presence of combustible gases and smoke. They can connect the sensor to a power supply and an LED module, then observe how the LED responds when gas or smoke is detected. This activity introduces the basics of gas sensing and demonstrates how MQ2 sensors are used in gas leak alarms, fire safety systems, and environmental monitoring.
