Product details

MQ-2 Sensor Introduction:
The Gas Sensing Material Used by MQ-2 Gas Sensor Is Tin Dioxide (Sn02) with Low Conductivity in Clean Air. When Combustible Gas Exists in the Environment Where the Sensor Is Located, the Conductivity of the Sensor Increases with the Increase of Combustible Gas Concentration in the Air.

A Simple Circuit Can Be Used to Convert the Change of Conductivity into an Output Signal Corresponding to the Gas Concentration. MQ-2 Gas Sensor Has High Sensitivity to Liquefied Gas, Propane and Hydrogen, and Is Also Ideal for Detecting Natural Gas and Other Combustible Steam. This Sensor Can Detect a Variety of Combustible Gases and Is a Low-Cost Sensor Suitable for a Variety of Applications.

Module Application:

It Can Be Used for Gas Leakage Monitoring Devices in Families and Factories, and Is Suitable for Detection of Liquefied Gas, Butane, Propane, Methane, Smoke, Etc;

Module Features:

1. Designed with High Quality Double-Sided Board, with Power Supply Indication and TTL Signal Output Indication;
2. with Do Switch Signal (TTL) Output and AO Analog Signal Output;
3. TTL Output Effective Signal Is Low Level. (When the Output Is Low, the Signal Light Is on, Which Can Be Directly Connected to the Single Chip Microcomputer Or Relay Module)
4. the Higher the Analog Output Voltage with the Higher the Concentration, the Higher the Voltage.
5. It Has Good Sensitivity to Liquefied Gas, Natural Gas, City Gas and Smoke.
6. There Are Four Screw Holes for Easy Positioning;
7. Product Dimensions: 32(L)* 20(W)* 22(H)
8. Long-Term Service Life and Reliable Stability
9. Fast Response Recovery Features

Electrical Performance:

Input Voltage: Dc5v Power Consumption (Current): 150ma
Do Output: TTL Digits 0 and 1(0.1 and 5V)
AO Output: 0.1-0.3V (Relatively Pollution-Free), the Highest Concentration Voltage Is about 4V
Special Reminder: After the Sensor Is Powered on, It Needs to Be Preheated for about 20 Seconds, and the Measured Data Is Stable. the Heating of the Sensor Is a Normal Phenomenon, Because There Are Heating Wire inside, If It Is Hot, It Is Not Normal.

Wiring Method:
1. VCC: Connect to the Positive Electrode of the Power Supply (5V)
2. GND: Connect to the Negative Electrode of the Power Supply
3. Do: TTL Switch Signal Output
4. Ao: Analog Signal Output
