Title 1, Gas Detection Module MQ-2 MQ-3 MQ-4 MQ-5 MQ-6 M...
MQ Sensor Modules MQ-2 MQ-3 MQ-4 MQ-5 MQ-6 MQ-7 MQ-8 MQ-9 MQ-135 Detection Smoke Methane Liquefied Gas Sensor Starter DIY Kit DC5V for Arduino
Feature:
1. High-Quality Dual Panel Design: This detection smoke methane liquefied gas sensor  is designed with high-quality dual panels, ensuring durability and reliability. It features a power indicator light and TTL signal output indicator, making it convenient to use.
2. Switch Signal Outputs: The switch signal of MQ sensor modules has both DO (TTL) and analog output AO. The TTL output provides an effective low-level signal, allowing direct connection to microcontrollers or relay modules.
3. Precise Analog Output: The analog output voltage corresponds to the concentration of the detected substance. The higher the concentration, the higher the voltage, providing accurate measurements.
4. Convenient Mounting: Equipped with four screw holes, this gas detection module  offers easy positioning and installation in various applications.
5. Longevity and Reliable Stability: With a long lifespan and reliable stability, this gas sensor module  ensures consistent performance over time. It exhibits fast response and recovery characteristics, providing accurate and timely results.



Specification:
Origin: Mainland China
Material: Metal
Electrical properties:
Input voltage: DC5V Power consumption (current): 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO output: 0.1-0.3V (relatively pollution-free),the maximum concentration voltage is about 4V
Special reminder: After the sensor is powered on, it needs to be preheated for about 20 seconds before the measured data is stable. Heating of the sensor is normal because there is an electric heating wire inside. If it is hot, it will be abnormal.
wiring:
VCC: power supply positive (5V)
GND: negative pole of power supply
DO: TTL switch signal output
AO: Analog signal output

Sensor introduction:
The gas-sensitive material used in gas sensors is tin dioxide (SnO2),which has low conductivity in clean air. When there is combustible gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of combustible gas in the air increases. A simple circuit can be used to convert changes in conductivity into an output signal corresponding to that gas concentration. The MQ-6 gas sensor has high sensitivity to propane and liquefied petroleum gas, and also has good sensitivity to natural gas. This sensor can detect a variety of flammable gases and is a low-cost sensor suitable for a variety of applications.

Module application:
Suitable for household or industrial detection devices for LPG (liquefied petroleum gas),propane, and LNG (liquefied natural gas). Excellent resistance to ethanol vapor and smoke interference.
Module features:
1. Adopt high-quality double-panel design, with power indicator and TTL signal output indicator;
2. With DO switch signal (TTL) output and AO analog signal output;
3. The TTL output valid signal is low level. (The signal light lights up when the output is low, and can be directly connected to a microcontroller or relay module)
4. The analog output voltage is 0~5V. The higher the concentration, the higher the voltage.
5. It has good sensitivity for detecting propane, butane, LPG and LNG.
6. There are four screw holes for easy positioning;
7. Product dimensions: 32(L)*20(W)*22(H)
8. Has long service life and reliable stability
9. Fast response recovery characteristics

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
