MQ-2 Smoke Gas Sensor Module / Liquefied Natural Gas Module

Product details

• Long size: 32 mm X 22 mm X 27 mm

• The main chip: LM393, ZYMQ-2 gas sensor

• Working voltage: DC 5V

Features:

•  A signal output instructions.

• Two-way signal output (TTL level output and analog output)

• TTL output signal for low level effectively.(when the low output electric signal lights at ordinary times, can be directly by single chip microcomputer)

• Analog 0~5V voltage, the higher the concentration, the higher the voltage.

• To the liquefied petroleum gas, natural gas, city gas has better sensitivity.

• In June and has long service life and reliable stability

• Rapid response recovery features

Application:

• Suitable for family or factory of gas leakage monitoring device, suitable for liquefied petroleum gas, butane, propane, hydrogen, methane, alcohol, smoke and other monitoring devices.

• Applicable occasions: MCU learning, electronic competition, product development, the graduation design...
