The Winsen MQ-2 Smoke Sensor is an original and brand-new smoke and propane gas sensor. With a long lifespan and low price, for domestic gas leakage and flammable gas alarm use.
The sensitive material of the MQ-2 gas sensor is SnO₂, which has lower conductivity in clean air. When the target flammable gas exists, the sensor’s conductivity gets higher along with the rising gas concentration. Users can convert the change of conductivity to correspond to the output signal of gas concentration through a simple circuit.
The MQ-2 gas sensor has a high sensitivity to propane and smoke and can also detect natural gas and other flammable steam well. It is at low cost and suitable for different applications of detecting kinds of flammable gases.
Applications:
It is widely used in domestic gas leakage alarms, industrial flammable gas alarms, and portable gas detectors.
Features:
1. Responsive to a wide range of gases
2. Compatible with 5V
3. Cost-efficient
Package Includes:
1 x Winsen MQ-2 Smoke Sensor
