dimension: 32mm X 22mm X height 27mm width

the main chip: LM393, ZYMQ-2 gas sensor

the working voltage: DC 5 V


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

V. Application:

Suitable for home or factory gas leakage monitoring device suitable for gas, butane, propane, methane, alcohol, hydrogen, smoke and other monitoring devices.

Applications: SCM learning, electronic competition, product development, graduation.
