Smoke sensor MQ2 (Digital/Analog)
This smoke sensor module with MQ2 Smoke sensor have both digital and analog outputs , you also can adjust the sensitivity with the potentioneter.
PIN Connection
4 pins as follows:
- VCC (5 V)
- GND (ground)
- Aout (Analog output)
- Dout (Digital output)
When connect to arduino, use digital pins in digital mode (high or low) and use analog pins for analog mode (diffrenet value for different smoke intensity).
