MQ-2: The MQ-2 is a multi-gas sensor capable of detecting various gases, including combustible gases, smoke, and hydrocarbons. It is commonly used in safety systems and smoke detectors.

MQ-6: The MQ-6 is a gas sensor specialized in detecting gases such as propane and butane. It is suitable for monitoring gas stoves and gas-fueled appliances.

MQ-135: The MQ-135 is a multi-gas sensor capable of detecting a wide range of harmful gases, including ammonia, benzene, and carbon dioxide. It is useful for monitoring air quality.

MQ-4: The MQ-4 is a gas sensor designed to detect methane and natural gas. It is commonly used in gas leak detectors.

MQ-8: The MQ-8 is a gas sensor specialized in detecting carbon monoxide (CO). It is suitable for use in CO alarm systems.

MQ-7: The MQ-7 is a gas sensor that detects both carbon monoxide and methane. It is used in home security systems and carbon monoxide detectors.

MQ-5: The MQ-5 is a gas sensor that detects various gases, including natural gas and propane. It enhances the safety of gas stoves and gas appliances.

MQ-9: The MQ-9 is a gas sensor that detects carbon monoxide (CO) and methane (CH4). It is useful in fire and gas alarm systems.

MQ-3: The MQ-3 is an alcohol gas sensor capable of detecting various alcohols, such as ethanol. It is often used in alcohol testers and breathalyzer devices.

Please note that each of these sensors is designed for detecting specific types of gases, and their applications vary based on the gases you want to detect or monitor.

  • Using high-quality dual-panel design,with power indicator and TTL signal output instructions.
  • The switching signal having a DO (TTL) output and analog output AO.
  • TTL output valid signal is low. ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
  • Analog output voltage with the higher concentration of higher voltage
  • There are four screw holes for easy positioning.
  • Has a long life and reliable stability
  • Rapid response and recovery characteristic

Input voltage : DC5V Power consumption ( current ): 150mA
DO output : TTL digital 0 and 1 ( 0.1 and 5V)
AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V
Special note: After the sensor is powered,needs to warm up around 20S,measured data was stable,heat sensor is a normal phenomenon,because the internal heating wire,if hot is not normal .

Wiring:

  • VCC: positive power supply (5V)
  • GND: power supply is negative
  • DO: TTL switching signal output
  • AO: analog signal output

    NOTE:

    After the sensor is powered, need to warm about 20S, measured data becomes stable, heat sensor is normal

Test program:Function: This version of the test program supporting

Use chip: AT89S52

Crystal: 11.0592MHZ

Baud rate: 9600
