Long size: 32 mm X 22 mm X 27 mm
The main chip: LM393, ZYMQ-2 gas sensor
Working voltage: DC 5V
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
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...
