4.hot sale sensor
5.fast delivery
Description:
Dual-way Signal Output: Analog output and TTL level output
High sensitivity to LPG, gas, alcohol, hydrogen and more
Fast response and recovery
Good steadiness and long service life
Great for home or factory gas leakage detection
Use for Detecting: Combustible gas such as LPG, butane, methane,
alcohol, propane, hydrogen, smoke, etc
Working Voltage: 5V DC
Three characteristics:
1, having a signal output instruction.
2, dual signal output (analog output, and TTL level output)
3, TTL output valid signal is low. (Low-level signal when the
output light can be directly connected to the microcontroller)
4, 0 ~ 5V analog output voltage, the higher the concentration the
higher the voltage.
5 of liquefied petroleum gas, natural gas, city gas has better
sensitivity.
6, has a long life and reliable stability
7, rapid response and recovery characteristics
Application:
Suitable for home or factory gas leakage monitoring device suitable
for gas, butane, propane, methane, alcohol, hydrogen, smoke and
other monitoring devices.
Specification:
the main chip: LM393, ZYMQ-2 gas sensor
the working voltage: DC 5 V
Detecting Range: 300 to 10000ppm
